The PIECAL 520B and 521B Thermocouple Simulators simulate a dedicated standard thermocouple curve over the entire industrial temperature range. The PIECAL 520B and 521B provide 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, while The PIECAL 521B has a miniature thermocouple connector on the top end for fast connections. The PIECAL 520B and 521B offer the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators.

The low cost PIECAL Model 520B and 521B are an “easy as PIE” to use thermocouple sources for checkout and calibration of all thermocouple instruments in the field, shop or control room.
