Elements of Liquid Inflated Temperature Controller
When the temperature of the controlled object varies, the volume of the material in the temperature sensing part of temperature controller will inflate or deflate, thus causing the film box which is connected to the temperature sensing part inflating or deflating too, then drives the switch on or off through a leverage function to keep a constant temperature.
Features
1. Accurate temperature control, reliable performance
2. Small on/off temperatures difference
3. A wide range of temperature control
4. Large over loaded current
Application
1. It's mainly used for the temperature control of household electrical appliances , such as showers, rolling-type washers, fan heaters etc.
2. It is well suited for electrothermal equipment, such as stainless steel full automatic water boilers, electrothermal fryers, baking stoves, electronic ovens, foodstuff machinery, medical equipment etc.
3. It is also widely used in refrigeration industry (kitchen cooling cabinets, preservation cabinets, refrigerators, ice-makers, rearing ponds, cold-drinks makers, heating machines) etc.

Notes:
(1) Client can make an order according to the characters of his product, and the range of temperature that needs to be controlled.
(2) In temperature controller fixing, keep temperature-sensing duct closely contact the surface where temperature needs to be controlled, to well fulfill its function.
(3) Do not press the temperature-sensing duct to be deformed in fixing to avoid influencing its performance.
(4) Do not make conductive gases or conductive matters enter into the temperature controller or stain its surface, to prevent its electric insulation from being influenced.
(5) Do not use over-length M4 wire for bracket fixing, otherwise temperature controller performance will be destroyed.
(6) Switch box is a ceramic item, and therefore shall be handled carefully.
(7) The bending radius of capillary shall not be less than 5mm.
