Electronical Temperature Sensors

This temperature sensor is for measuring the temperature of liquid and gaseous media in engines, sets of machines and utility vehicles.

A Pt 1000 thin-film precision resistor is used as the measuring element. The temperature-dependent resistance of the Pt 1000 is evaluated by an electronic circuit and outputted as a temperature-dependent voltage at the sensor‘s output. The interrelationship between temperature and voltage corresponds to the characteristic curve for the Pt 1000 and is thus nearly linear.

The assignment between temperature and output voltage is nearly freely selectable, the lesser temperature corresponding to the lesser output voltage. The sensor‘s lowest possible output voltage is 0.1 V and its greatest is 10 V. The output is overload-proof and short-circuit-proof.

The sensor has no mechanical moving parts and so is not susceptible to vibration and soiling.
