This unit is ideal for use in applications where continuous control in relation to ambient temperature is required. It can also be used as a temperature switch for the operation of another device.
Possible applications include the continuous control of temperature in systems like air conditioning, central heating, refrigeration, etc. The continuous monitoring of temperature within audio amplifiers, radio transmitters, or internal combustion engines, is also possible.
The relay activation point can be adjusted within a temperature range of minus 45°C to +145°C. The relay activation hysteresis can be adjusted within a range from 1°C to 7°C. Average accuracy is ±0.5°C. Temperature sensor is in a TO92 package and can be mounted remotely from the PCB.
