Equipment Required


a)      Temperature Bath.

b)      Switch Contact Monitoring Device

 




Procedure of the Temprature Switch Calibration

Ø  Remove the temperature sensor from the process.

Ø  Connect test equipment

Ø  For high high-temperature switch (TSH), place the sensor in a calibrated bath/block test standard at a temperature below the specified trip point and allow it to stabilize.

Ø  For low low-temperature switch (TSL), place the sensor in a calibrated bath/block test standard at a temperature above the specified trip point and allow it to stabilize.

Ø  Slowly increase or decrease the temperature to obtain the trip point.

Ø  Slowly decrease or increase the temperature to obtain a reset point.

Ø  Repeat ―X‖ times for repeatably.
