KSD301-R bimetallic thermostat is a kind of miniature hermetically sealed bimetal temperature limiter (1/2" disc). It is of single-pole single-throw structure and works under resistive load. This safety limiter is in wide use in a great variety of compact type home appliances, such as coffee maker, water dispenser, toaster, microwave oven, electric pad and portable icebox etc., to provide temperature control or temperature protection.(KSD301)
Advantages of manual temperature sensor:
- Easy mounting.
- High precision.
- High durability.
- Rapid heat transmission.
- No breakdown, no flashover.
- Every product will be tested, extremely high temperature pass rate.
