Kaye IRTD (Intelligent Resistant Temperature Device)

Highly Accurate Traceable Temperature Standard

The Intelligent Resistant Temperature Device (IRTD) is a secondary standard with a completely self-contained measurement system, including electronics for calibration and temperature conversion. Kaye's IRTD provides ultra-high accuracy temperature data to your computer with no additional measurement or readout equipment required.

The IRTD removes common sources of error because its integrated electronics and sensor are calibrated as a single instrument. Analog to digital conversion is automatic - no manual interpolations or calculations are necessary.

The self-contained IRTD allows you to cut system error in half. For thermal validation applications, the IRTD communicates directly with the Kaye system. During sensor calibration / verifications, sensors are compared against the IRTD and offsets are automatically calculated and stored.

The broad temperature range from -196 to 420°C, enables it to be used in virtually all temperature validation applications. The IRTD is an integral part of Kaye's automated sensor calibration system and communicates directly with all Kaye Validation systems. With an accuracy of +/- 0,025, the IRTD delivers a 4 to 1 ratio for calibrating sensors to 0.100°C.

The temperature standard can be utilised for confirming the accuracy of other temperature devices. Therefore, Kaye has developed IRTDWin™ software. This software provides one convenient interface screen that lets you track probe stability, numerically and graphically, as well as confirm system accuracy.
