1 The KTY 84 is a temperature-dependent semi-conductor with a positive temperature coefficient. Typical for these sensors is the monitoring of temperatures and limit values in the field of industrial metrology. The sensor s small dimensions render it as ideal for installation in windings as a thermal overload protection. For installation in electric motor, generator and transformer windings. Version for temperature monitoring of motor bearings Temperature monitoring of coolants PRODUCT INFORMATION KTY 84 is a temperature-dependent semi-conductor with a positive temperature coefficient. Typical for these sensors is the monitoring of temperatures and limit values in the field of industrial metrology. The sensor s small dimensions render it ideal for installation in windings as a thermal overload protection. Typical applications The sensor s very high precision and reliability make it suitable for a variety of applications within industry and vehicles. Industrial applications Overheating protection in electric motors, generators, transformers, power supply units, motor bearings, etc. Temperature monitoring in process flows Temperature compensation for microprocessors Vehicle applications Oil temperature, oil level Water temperature Diesel injection Transmission Coolants for engines Air conditioning Description/Function The KTY 84-1 series of temperature sensors is a semi-conductor (with anode/cathode connection) that has a resistance temperature characteristic curve that is nearly linear over the entire temperature range. The temperature coefficient is positive. KTY 84 is available in three versions. KTY , (our stan dard sensor), KTY and KTY The differences between the variants can be found in the technical data. NOTE! It is very important that the polarity is checked when connecting the sensor. If the sensor isincor rectly connected the resistance curve will not match with the data sheet or connected electronicapparatus. Properties Temperature monitoring at a low cost within a wide temperature spectrum C (temperature resistance for wiring, insulation, etc. selected according to the specific application) Greater output than the PT 100 sensor Very long life High long-term stability Low weight Short thermal time constant Colour/Connection KTY 84 is a semi-conductor where one end is an anode (plus) and the other a cathode (minus). A wide range of colour combinations is available on the market. The sensor s ring marking can be checked to ensure the wiring is correct. The ring is the cathode side. It is therefore of the utmost importance to know what the wire colour codes are for the anode and cathode in those cases where the sensor is embedded. To verify the polarity by way of measurement requires heating of the sensor to see when the resistance follows the temperature curve as shown in the data sheet.

The thermal time constant is the time taken for the sensor to reach 63.2% of the total temperature difference. For example, if a sensor with a temperature of 25 C is moved to an environment with an ambient temperature of 100 C, the time of the sensor to reach a temperature of 72.4 C is the thermal time constant. T 63.2% = 25 C * (100 C - 25 C)= 72.4 C 2. Inert liquid, e.g. FC 43 manufactured by the 3M company Carbex AB Box Vadstena Sweden Tel +46 (0) info@carbex.se 5/8
