How To Calibrate Temperature switch

How To Calibrate Temperature switch/Procedure for Temperature switch calibration.

Equipment required

1. Temperature Bath.
2. Switch Contact Monitoring Device.

The procedure of Temperature Switch Calibration:

1. Remove the temperature sensor from the process.
2. Connect test equipment
3. For high-Temperature Switch (TSH), place the sensor in a calibrated bath/block test standard at a temperature below the specified trip point and allow stabilizing.
4. For low-Temperature Switch (TSL), place the sensor in a calibrated both/block test standard at a temperature above the specified trip point and allow it to stabilize.
5. Slowly increase or decrease the temperature to obtain a trip point.
6. Slowly decrease or increase the temperature to obtain reset point.
7.  Repeat ―X‖ times for repeatably.
