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