PIECAL 520B
Single T/C Simulator 


The PIECAL 520B Thermocouple Simulator simulates a dedicated standard thermocouple curve over the entire industrial temperature range.

The PIECAL 520B provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition and computer systems.

The PIECAL 520B is cold-junction compensated for changes in ambient temperature. It offers high performance and functions by exceeding the accuracy and functions of many of the higher priced thermocouple calibrators.

The low cost PIECAL Model 520B is an “EZ-as-PIE" to use thermocouple source for checkout and calibration of all thermocouple instruments in the field, shop or control room.
