Thermostat

WK-R series pressure type thermostat consists of a temperature sensing packet,conductive capillaries and elastic elements and works under the principle of liquid expansion heating.When the temperature sensing packet is heated,the temperature sensing liquid gets expanded to push the elastic element to form a displacement and thus to push the micro-switch to break the circuit down while the switch can also automatically close when the temperature of the object under control reduces below the set value,thus getting a constant temperature control.
The technical parameter as follows:
1.Electric performance:16A250V-10A440
2.Disconnection temperature is designed according to user's request from (-40-300Centigrade).
3.the life:10 by 10000times
4.Electric intensity:AC2500V/Min
5.Insulating resistance:>=50Megaohm
6.Contact resistance:<30Megaohm
The performance parameter:
