Thermocouple Input

The most common measurement in data acquisition systems is temperature. The most commonly used sensor in temperature measurement is the thermocouple (TC). UEI provides a variety of thermocouple measurement boards compatible with our PowerDNA cube. In addition to the measurement boards, we also provide screw terminal connectivity panels that provide the high quality Cold-Junction temperature sensing required to make an accurate thermocouple measurement.

Software included with the PowerDNA performs linearization for all common TCs as well as cold-junction compensation. Users may choose to automatically receive data in either °C or °F. Users of non-standard TCs, or those who do not wish to utilize the built-in linearization routines, may also have data returned in Volts.

If you have any questions please call us at: (508)-921-4600 or email us at: info@ueidaq.com
