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.

PeakTech Prüf- und Messtechnik GmbH
A type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component.[1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value. Readings should be reasonably accurate if the capacitor or inductor device under test does not have a significant resistive component of impedance. More advanced designs measure true inductance or capacitance, as well as the equivalent series resistance of capacitors and the Q factor of inductive components.
