Uniform Temperature Reference reducing Temperature gradients in Thermocouple Installations
Description
The Kaye (UTR) is a passive device, requiring no external power. Its design addresses all thermal errors induced by static and dynamic conditions providing a superior temperature stable environment. Thermocouple terminations are made by screw terminals on one side of the plate while output connections to the measuring device are made via copper terminations on the other side of the plate.
A highly accurate NIST traceable RTD is mounted to the plate to provide measurement of the plate temperature. The UTR’s rugged design and ability to handle extreme temperature and vibration make it ideal for mounting near engine test stands.. This minimizes thermocouple runs and expensive gold plated feedthrough for getting sensors outside the harsh environment.
The UTR also reduces the possibility of temperature gradients to a + 0.5°C error due to a 40°C step change in ambient; twice the accuracy of conventional UTRs.
