Our PXI Millivolt Thermocouple Simulator modules provide 32, 24, 16 or 8 channels of accurate low sources. They are ideal for the simulation of thermocouples and can be used for sensor emulation in ECU testing. The channels can be operated with one of three voltage ranges covering most thermocouple types. We can also supply connection solutions allowing the easy integration of the Thermocouple Simulator into your test system
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.
