This series of PXI Thermocouple Simulator Modules is available in a choice of 32, 24, 16 or 8 channels—each channel providing a low-voltage output across two connector pins capable of providing ±20mV with 0.7µV resolution, ±50mV with 1.7µV resolution and ±100mV with 3.3µV resolution, covering most thermocouple types.
These thermocouple simulators use two wire outputs with a remote output reference sense to ensure the modules deliver accurate low-level voltages, even if the system has common mode voltages present. In addition, each simulation channel is also able to provide an open circuit setting to simulate faulty wiring connections to a sensor.
For improved accuracy each channel of the Low-Voltage Source carries accurate calibration data stored on the module. The module also includes a calibration multiplexer for module test and verification purposes.
