Bimetallic High Temperature Limit Switch HVAC System , Thermal Sensor

 

 

 

Quick Detail:

  1. Thermal Sensor
  2. -10250 Celsius degree
  3. Life cycle:100,000 times
  4. Certifications:CQC, TUV, UL, CB, ROHS
  5. Function: temperature control

 

Description:

 


KI-31 serial products are the temperature controllers taking bimetallic strip as the temperature-sensing unit. In case of normal operation the electrical appliance, the bimetallic strip is in a free state; the contact point is in a state of close/open. When the temperature reaches the action temperature, the bimetallic strip performs quick action generates caused by internal stress due to heating; open/close the contact point; disconnect/connect the circuit; thus, the temperature is in control. When the electrical appliance is cooled to the recovery temperature, the contact point automatically opens/closes to recover normal operation state.

 

Application:

 


Widely used in electrical heating appliances like water dispenser, water heater, sandwich bread baker, dishwasher, dryer, sterilizing cupboard, micro-wave oven, electric heating coffee pot, electric cooker, refrigerator, air-conditioner, laminator, heater of auto seat.
