INDUSTRIAL MEASUREMENT
Ice Point & Uniform Temperature References
Temperature References improve accuracy of thermocouple measurements.
Obtaining high-accuracy measurements from thermocouples requires instrumentation designed to minimize errors. Thermocouple conformity, the cold junction and its reference, the A/D converter and other analog system electronics all contribute to the overall system error. While the cold junction (termination of thermocouple to copper) can contribute significantly to system error, this error can be minimized with a high-accuracy temperature reference.

The GE Kaye Uniform Temperature References (UTRs) provide cold junction temperature measurement for up to 64 thermocouples with twice the accuracy of conventional models. This high level of accuracy is achieved through remote monitoring via a NIST-traceable RTD, which automatically performs compensation calculations. GE Kaye UTRs are passive mechanical devices requiring no external power. This highly accurate and durable design has been a standard in the aerospace industry since 1974, and is ideally suited for applications involving extreme temperatures, set-up flexibility, or uncontrolled environments.

- Operates in temperature extremes
- Easily reconfigured for different thermocouple types
- Can be installed near test article in the test environment
The criteria for selecting a reference type include environmental considerations (temperature range, vibration, etc.), the need for flexibility, and required accuracy. For more permanent installations with less extreme temperature requirements consider GE Kaye's Ice Point Reference.
GE Kaye's Ice Point References provide the highest level of accuracy in automatic referencing - zero long-term drift maintaining reference temperature at 0C. Ice Point References are available in rack-mount or portable configurations with capacity for up to 75 thermocouples.
