8 Data Logger Layout Charging port A micro USB connector to charge the devices battery, any 5v USB charging device can be used to recharge this logger. Charge time is dependent on charger but maximum charge rate is 500 milliamps, at this rate the unit will take just under 4 hours to fully charge. Spare Ethernet Port This port is currently unused. Debug port Micro USB Used to program and debug the data logger ON/Off Switch turns the device power from battery on and off Charging Complete This LED indicates that the battery is fully charged when on. Power On This blue LED indicates the power is on when on. Battery Low This LED indicates that the unit needs charging when on. GPS Status (not shown) A solid red light means that the GPS receive is on but does NOT have a lock, a blinking red light indicates a GPS lock. Unit Mode Select The user presses and holds this button to select functionality o 1 Second Press (acknowledged with 1 audio beep) = Start new log, if one is already running a new one will be started in a new file o 2 Second Press (acknowledged with 2 audio beeps) = Stop Logging o 3 second press (acknowledged with 3 audio beeps) = This requests that the unit sync itself to GPS time when it is receiving the correct GPS data, even if the GPS light is flashing it may take a while for this to happen. A long beep will occur when the unit is sync d. Unit Status When a green LED is flashing the unit is logging, when a yellow LED is on it means there is no Micro SD card detected. Micro SD Port This is where the Micro SD card is inserted, the Micro SD card is where the logger data is recorded to, it needs to be FAT32 and smaller than 32GB and have a unit.cfg file created by the configuration GUI on it. GPS Antenna Connector This is where the GPS antenna connect to the device. Page 7 of 19

9 Quick Start Guide Insert a Micro SD car into the slot on the bottom of the data logger. Turn On the Device. Check you do not have a low battery warning. If you want to have GPS data from the start (optional) of the test then you have to wait until the red GPS light is flashing, the unit will log data without GPS information without any issues. When you want to start recording data press and hold the user input button for one second or until you hear a single beep. When a new log is created the strain gauges are zero d so it is important that the seat post is unloaded at that point in time, i.e. no one is sitting on it. When you want the unit to stop logging press and hold the user input button for 2 seconds or until you hear two beeps. Try and do this before you pull the micro SD card out or your data maybe corrupted. A new file can be created without having to stop the old one first, this happens automatically. To sync the unit precisely to GPS time press and hold the user input button for three seconds, or until you hear three beeps. The unit will then wait until it has received the appropriate GPS message to sync the time, the sync completion will be indicated by a beep lasting a second in duration, the time for this to happen can vary greatly on GPS signal quality. The accuracy of the sync should in theory be within 1ms of GPS time. To read the data pull out the micro SD card and insert it into an SD card reader attached to a computer, you should see something like this image: The data is contained in the.csv file, the other file, unit.cfg is the configuration file for the unit and needs to be kept there with that exact file name. Remember to turn off the unit and charge it, unit operation time from full charge is approx. 3 hrs. Page 8 of 19

10 Configuration Software To configure the unit please visit to download software. Go to the page where you purchased the unit from and the latest software will be there. Once the software is downloaded and installed please save the unit.cfg config file produced to the micro USB stick that is going to be inserted into the unit. Do not rename this file. Page 9 of 19

11 Application Notes Accelerometers When connecting an accelerometer please tie the negative side of the A to D channel to GND for the A to D. For example if AD1_1+ is connected to an accelerometer output, please make sure that AD1_1- is connected to AD1_GND. K-Type Thermocouples If you select a channel as a K-Type thermocouple and don t connected one this value will be the internal box temperature. Strain Gauges Metis Engineering offer consultation and bridge completion modules for strain gauge installation. National Instruments have a good page on the different strain gauge setups Appendix A has the full article. Page 10 of 19

12 Appendix A Strain Gauges What is strain? In mechanical testing and measurement, you need to understand how an object reacts to various forces. The amount of deformation a material experiences due to an applied force is called strain. Strain is defined as the ratio of the change in length of a material to the original, unaffected length, as shown in Figure 1. Strain can be positive (tensile), due to elongation, or negative (compressive), due to contraction. When a material is compressed in one direction, the tendency to expand in the other two directions perpendicular to this force is known as the Poisson effect. Poisson s ratio (v), is the measure of this effect and is defined as the negative ratio of strain in the transverse direction to the strain in the axial direction. Although dimensionless, strain is sometimes expressed in units such as in./in. or mm/mm. In practice, the magnitude of measured strain is very small, so it is often expressed as microstrain (µε), which is ε x Figure 1. Strain is the ratio of the change in length of a material to the original, unaffected length. The four different types of strain are axial, bending, shear, and torsional. Axial and bending strain are the most common (see Figure 2). Axial strain measures how a material stretches or compresses as a result of a linear force in the horizontal direction. Bending strain measures a stretch on one side of a material and the contraction on the opposite side due to the linear force applied in the vertical direction. Shear strain measures the amount of deformation that occurs from a linear force with components in both the horizontal and vertical directions. Torsional strain measures a circular force with components in both the vertical and horizontal directions. Page 11 of 19

13 Figure 2. Axial strain measures how a material stretches or pulls apart. Bending strain measures a stretch on one side and a contraction on the other side. How do you measure strain? You can measure strain using several methods, but the most common is with a strain gage. A strain gage s electrical resistance varies in proportion to the amount of strain in the device. The most widely used strain gage is the bonded metallic strain gage. The metallic strain gage consists of a very fine wire or, more commonly, metallic foil arranged in a grid pattern. The grid pattern maximizes the amount of metallic wire or foil subject to strain in the parallel direction. The grid is bonded to a thin backing called the carrier, which is attached directly to the test specimen. Therefore, the strain experienced by the test specimen is transferred directly to the strain gage, which responds with a linear change in electrical resistance. Page 12 of 19

14 Figure 3. The electrical resistance of metallic grid changes in proportion to the amount of strain experienced by the test specimen. A fundamental parameter of the strain gage is its sensitivity to strain, expressed quantitatively as the gage factor (GF). GF is the ratio of the fractional change in electrical resistance to the fractional change in length, or strain: The GF for metallic strain gages is usually around 2. You can obtain the actual GF of a particular strain gage from the sensor vendor or sensor documentation. In practice, strain measurements rarely involve quantities larger than a few millistrain (e x 10-3). Therefore, to measure the strain, you have to accurately measure very small changes in resistance. For example, suppose a test specimen undergoes a strain of 500 me. A strain gage with a GF of 2 exhibits a change in electrical resistance of only 2 (500 x 10-6) = 0.1%. For a 120 Ω gage, this is a change of only 0.12 Ω. To measure such small changes in resistance, strain gage configurations are based on the concept of a Wheatstone bridge. The general Wheatstone bridge, illustrated in Figure 4, is a network of four resistive arms with an excitation voltage, VEX, that is applied across the bridge. Page 13 of 19

15 Figure 4. Strain gages are configured in Wheatstone bridge circuits to detect small changes in resistance. The Wheatstone bridge is the electrical equivalent of two parallel voltage divider circuits. R1 and R2 compose one voltage divider circuit, and R4 and R3 compose the second voltage divider circuit. The output of a Wheatstone bridge, Vo, is measured between the middle nodes of the two voltage dividers. From this equation, you can see that when R1 /R2 = R4 /R3, the voltage output VO is zero. Under these conditions, the bridge is said to be balanced. Any change in resistance in any arm of the bridge results in a nonzero output voltage. Therefore, if you replace R4 in Figure 4 with an active strain gage, any changes in the strain gage resistance unbalance the bridge and produce a nonzero output voltage that is a function of strain. Types of strain gages The three types of strain gage configurations, quarter-, half-, and full-bridge, are determined by the number of active elements in the Wheatstone bridge, the orientation of the strain gages, and the type of strain being measured. Quarter-Bridge Strain Gage Configuration Type I Measures axial or bending strain Requires a passive quarter-bridge completion resistor known as a dummy resistor Requires half-bridge completion resistors to complete the Wheatstone bridge R4 is an active strain gage measuring the tensile strain (+ε) Page 14 of 19

16 Figure 5. Quarter-Bridge Strain Gage Configurations Configuration Type II Ideally, the resistance of the strain gage should change only in response to applied strain. However, strain gage material, as well as the specimen material to which the gage is applied, also responds to changes in temperature. The quarter-bridge strain gage configuration type II helps further minimize the effect of temperature by using two strain gages in the bridge. As shown in Figure 6, typically one strain gage (R4) is active and a second strain gage(r3) is mounted in close thermal contact, but not bonded to the specimen and placed transverse to the principal axis of strain. Therefore the strain has little effect on this dummy gage, but any temperature changes affect both gages in the same way. Because the temperature changes are identical in the two strain gages, the ratio of their resistance does not change, the output voltage (Vo) does not change, and the effects of temperature are minimized. Figure 6. Dummy strain gages eliminate effects of temperature on the strain measurement. Half-Bridge Strain Gage You can double the bridge s sensitivity to strain by making both strain gages active in a half-bridge configuration. Page 15 of 19

17 Configuration I Configuration II - Bending Strain Only Figure 7. Half-bridge strain gages are two times more sensitive than quarter-bridge strain gages. Configuration Type I Measures axial or bending strain Requires half-bridge completion resistors to complete the Wheatstone bridge R4 is an active strain gage measuring the tensile strain (+ε) R3 is an active strain gage compensating for Poisson s effect (-νε) This configuration is commonly confused with the quarter-bridge type II configuration, but type I has an active R3 element that is bonded to the strain specimen. Configuration Type II Measures bending strain only Requires half-bridge completion resistors to complete the Wheatstone bridge R4 is an active strain gage measuring the tensile strain (+ε) R3 is an active strain gage measuring the compressive strain (-ε) Full-Bridge Strain Gage A full-bridge strain gage configuration has four active strain gages and is available in three different types. Types 1 and 2 measure bending strain and type 3 measures axial strain. Only types 2 and 3 compensate for the Poisson effect, but all three types minimize the effects of temperature. Configuration I - Only Bending Strain Configuration II - Only Bending strain Configuration III - Only Axial Strain Page 16 of 19

18 Configuration Type I Figure 8. Full-Bridge Strain Gage Configurations Highly sensitive to bending strain only R1 and R3 are active strain gages measuring compressive strain ( e) R2 and R4 are active strain gages measuring tensile strain (+e) Configuration Type II Sensitive to bending strain only R1 is an active strain gage measuring the compressive Poisson effect ( νe) R2 is an active strain gage measuring the tensile Poisson effect (+νe) R3 is an active strain gage measuring the compressive strain ( e) R4 is an active strain gage measuring the tensile strain (+e) Configuration Type III Measures axial strain R1 and R3 are active strain gages measuring the compressive Poisson effect ( νe) R2 and R4 are active strain gages measuring the tensile strain (+e) How do I choose the right strain gage? Once you have decided the type of strain you intend to measure (axial or bending), other considerations include sensitivity, cost, and operating conditions. For the same strain gage, changing the bridge configuration can improve its sensitivity to strain. For example, the full-bridge type I configuration is four times more sensitive than the quarter-bridge type I configuration. However, full-bridge type I requires three more strain gages than quarter-bridge type I. It also requires access to both sides of the gaged structure. Additionally, full-bridge strain gages are significantly more expensive than half-bridge and quarter-bridge gages. For a summary of the various types of strain gages, refer to the following table.

Grid Width Using a wider grid, if not limited by the installation site, improves heat dissipation and enhances strain gage stability. However, if the test specimen has severe strain gradients perpendicular to the primary axis of strain, consider using a narrow grid to minimize error from the effect of shear strain and Poisson strain. Nominal Gage Resistance Nominal gage resistance is the resistance of a strain gage in an unstrained position. You can obtain the nominal gage resistance of a particular gage from the sensor vendor or sensor documentation. The most common nominal resistance values of commercial strain gages are 120 Ω, 350 Ω, and 1,000 Ω. Consider a higher nominal resistance to reduce the amount of heat generated by the excitation voltage. Higher nominal resistance also helps reduce signal variations caused by lead-wire changes in resistance due to temperature fluctuations. Temperature Compensation Ideally, strain gage resistance should change in response to strain only. However, a strain gage s resistivity and sensitivity also change with temperature, which leads to measurement errors. Strain gage manufacturers attempt to minimize sensitivity to temperature by processing the gage material to compensate for the thermal expansion of the specimen material for which the gage is intended. These Page 18 of 19

20 temperature-compensated bridge configurations are more immune to temperature effects. Also consider using a configuration type that helps compensate for the effects of temperature fluctuations. Installation Installing strain gages can take a significant amount of time and resources, and the amount varies greatly depending on the bridge configuration. The number of bonded gages, number of wires, and mounting location all can affect the level of effort required for installation. Certain bridge configurations even require gage installation on opposite sides of a structure, which can be difficult or even impossible. Quarterbridge type I is the simplest because it requires only one gage installation and two or three wires. Page 19 of 19
