Liquid expansion thermostat (pressure-type temperature control switch)
Liquid expansion thermostat is mainly used in large-scale electrical appliances, Electric oven temperature controller, Its main features are:
Temperature adjustable, accurate temperature control, long life, Stable and reliable, open stop temperature is small, Temperature control range, Overload current and easy installation and so on.
And ordinary bimetal comparison:Bimetallic thermostat maximum temperature can only reach 250 ℃, The liquid expansion thermostat up to 450 ℃.
Liquid-type thermostat mounted liquid common are:Mercury, xylene, methanol ether, glycerol, water, ethanol.
