Discontinued- Pie 521B is manufacturer recommended replacement.
8 Type T/C Plus mV Simulator
The Practical Instrument Electronics (PIE) Model 521 Thermocouple Simulator simulates a standard thermocouple curve over the entire industrial temperature range. The Model 520/521 provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The Model 521 provides a miniature thermocouple connector. 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 521 is an “easy as PIE” to use thermocouple source for checkout and calibration of all thermocouple instruments in the field, shop or control room.
