Precision RTD Simulator
RTD Series
-
The RTD Series Precision RTD (Resistance Temperature Detector) Simulator provides a very broad-range of absolute resistance values that replace RTD's and thermocouples. Thermocouples present a resistance that depends on the temperature. The RTD simulator effectively replaces an RTD to test, analyze, and calibrate RTD measuring systems. The RTD Series simulator is a precision resistance source with excellent characteristics of accuracy, stability, temperature coefcient, and power coefcient. All these features serve to make it a laboratory resistance standard, exceeded in performance only by stand-alone standard resistors. The special design of the RTD Series provides absolute accuracy, and requires no zero resistance subtraction from any setting Special design of the RTD virtually eliminate zero resistance and switch contact variations, providing the specified absolute accuracy over the entire range.
