Capillary ThermostatCapillary Thermostat The volume of the material in the temperature sensing part of temperature controller will inflate or deflate when the temperature of the controlled object varies, which causes the film box that is connected to the temperature sensing part inflating or deflating, then drives the switch on or off through a leverage function to keep a constant temperature. WK Series Liquid Inflated Temperature Controller is characterized by accurate temperature control, reliable, small on/off temperatures difference, a wide range of temperature control and large over loaded current etc. Snap-Action ThermostatSnap-Action ThermostatKSD series is a Small-sized bimetal thermostat with a metal cap,which belongs to thermal relays family .The main principle is that one function of bimetal discs is snap action under the change of sensing temperature, The snap action of disc push the action of the contacts through the inside structure, then caused on or off the circuit finally,It's can be used different insulating materials to satisfy the customers' request ,the main insulator is bakelite, PPS and ceramics etc. It is a small type temperature controller. And it has fixed temperature property, don't need to adjust,reliable action, long life and little wireless interference.
Bimetal ThermostatBimetal Thermostat Applicable to be used as the function of temperature adjustment and control for the warm-air machine, water heater, milk-heater, electric cooker, electric iron, electric heater.
Designed temperature: 0~90℃
Temp. control range: 6~30℃ 6-35℃ 5-55℃ 0-70℃ 5-75℃
Voltage and current: AC250V 16A
Thermal ProtectorThermal Protector This thermostat is rectangle,small size,regular act-temperature,the action rapid,reliable,unelectric-arc,and longevity. It can install at narrow position or set in some products.
The Series use the bimetal as the component of feel-temperature, when the temperature change, the bimetal change the shape so the contact-point act quickly, thereby the electric circuit break off.
Kettle ThermostatKettle ThermostatSuitable for temperature control of electric kettle
The bimetal piece has high quality and acumen
The insulated plastic material could be ensured high temperature Steam automatic skip protection and dry burn prevent protection for safer use Reasonable configuration and easy assemble, wide range temperature, long life.
Twinkling ThermostatTwinkling ThermostatTwinkling thermostat can be installes and fixed on the heating body or shelf through rivets or aluminum board.Through conduction and radiation ,it can sense the temperature.The installing position is free,and it has fine temperature controlling result and little magnetic interference.The compensation temperature controller can control the temperature and minish the fluctuation of temperature through absorbing self heat. It is widely used for biscuit machine, stove,rice cooker,fried pan,roasted pan,electric iron,heating machin etc.
