Single T/C Simulator

The Practical Instrument Electronics (PIE) Model 520 Thermocouple Simulator simulates a dedicated standard thermocouple curve over the entire industrial temperature range. The Model 520 provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. Model 520 provides 18” extension wire output and is cold-junction compensated for changes in ambient temperature. The PIE Model 520 offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators.

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