The RTD Simulator Series is ideal where applications of Resistance Temperature Detector (RTD) simulation require exact low value resistance without "zero" and contact resistance effects.

If this simulator is substituted for any RTD, the rest of the system may be calibrated or examined. Special designs virtually eliminate zero resistance and switch contact variations, providing the specified absolute accuracy over the entire range.

The RTD Simulator series is available in 4 models that vary by resistance range and precision. The RTD-Z is the choice for the most demanding RTD Simulation applications. These units have a 50 ppm (0.005%) absolute accuracy. The RTD-X series is more cost effective but still quite precise with a 100 ppm (0.01%) absolute accuracy

All RTD Simulator models have 6 decades. The units either have a 1 mΩ resolution with a max resistance of 1,000 Ω, which is best for PT-100 or a 10 mΩ resolution with a max resistance of 10,000 Ω, which is best for PT-1000's. The minimum resistance, or the lowest you can dial the unit, for all models is 10 Ω.
