Please contact First Sensor. Specificion notes: 1. Total accuracy is the combined error from offset and span calibrion, linearity, pressure hysteresis, and temperure effects. Linearity is the measured deviion based on a straight line. Hysteresis is the maximum output difference any point within the opering pressure range for increasing and decreasing pressure. Calibrion errors include the deviion of offset and full scale from nominal values.. Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure. 3. Proof pressure is the maximum pressure which may be applied without causing durable shifts of the electrical parameters of the sensing element. 4. Burst pressure is the maximum pressure which may be applied without causing damage to the sensing element or leaks to the housing. 5. The HCE common mode pressure is for all devices up to 500 and 7 for all other devices. Common mode pressure is the maximum pressure th can be applied to both s of a differential pressure sensor simultaneously without damaging the sensor housing. 6. Extended temperure ranges on request. Please contact First Sensor. 7. delay time between pressure change the pressure die and signal change the output. 8. The response time depends on the adjusted internal A/D resolution of the sensor. For 14 bit it is typ. 1 ms. Other A/D resolutions and reponse times are available on request. Please contact First Sensor for further informion. 9.

SPI - SERIAL PERIPHERAL INTERFACE Introduction The HCE is capable to genere a digital output signal. The device runs a cyclic program, which will store a corrected sensor value with 14 bit resolution about every 500 µs within the output registers of the internal ASIC. This cyclic program runs independent from the bus communicion. In order to use the pressure sensor for digital signal readout, it should be connected to a SPI Master device. SPI specifies four signals: The clock (CLK) is genered by the master and input to all slaves. MOSI carries da from master to slave. MISO carries da from slave back to master. A slave select line (SS) allows individual selection of a slave device. SPI Modes A pair of parameters called clock polarity (CPOL) and clock phase (CPHA) determine the edges of the clock signal on which the da are driven and sampled. Each of the two parameters has two possible stes, which allows for four possible combinions, all of which are incompible with one another. In general the HCE series sups all combinions of clock phase (CPHA) and polarity (CPOL). By default it is programmed to CPHA = 0 and CPOL = 0, which means th da transmission starts with the rising first clock edge (see Fig 1). Slave select The falling edge of the SS line indices the beginning of the transfer. Additionally the SS line must not be neged and reasserted between the three bytes to be transmitted. Da operion The MOSI line should always be set to high level. So there is no da transmission from master to slave. Because of internal configurion the slave will answer the first byte with an FFxh. The second and third byte contain the 15 bit pressure informion (see Fig. ).
