Thermocouples are inexpensive, reliable, and widespread temperature sensors. The voltage differential on their leads can be used to calculate the temperature.
The MonoDAQ U-X comes with preinstalled voltage-temperature correlation functions for most available thermocouples. In order to use them simply select the “Thermocouple ” function and select the type from the type drop-down menu.
Single thermocouple input
The images show the thermocouples with their yellow connectors for illustrative purposes only.
The thermocouples should be connected directly to the U-X (removing the yellow connectors if the thermocouple comes with them).
Extending the thermocouple wires prevents the cold junction compensation and causes a measurement error.
Up to four thermocouples can be connected to a single MonoDAQ U-X device at the same time.
