Published:2011/4/17 23:01:00 Author:Nicole | Keyword: temperature regulator | From:SeekIC

This circuit adopts thermal resistor K18. It has large surface and it is propitious to fix, it also can drive large load, it is always made into clavate and fixed in sensor housing. It is connected into bridge structure, and the temperature given value is adjusted by potentiometer R1, the output circuit is controlled by relay. The main technical data: the work voltage: 30V(-15~+10%); the adjustable temperature: 160~185℃; the allowable environmental temperature: 0~70℃; the temperature error(environmental temperature is in the range of 20~70℃): 0.5℃; the temperature difference between relay turns on and off: 1℃.
