(general physics) an accurate type of thermometer in which temperature is calculated from the resistance of a coil of wire (usually of platinum) or of a semiconductor placed at the point at which the temperature is to be measured . Algorithms - temperature written by administrator monday, 06 december 2010 13:45 platinum resistance thermometers within a limited range several metals and alloys have an approximately linear resistivity alteration depending on temperature. Platinum rtds possess unparalleled long term stability and consequently a platinum resistance thermometer is the primary interpolation instrument used by nist, the national institute of standards and technology. Platinum resistance thermometer resistance thermometers, also called resistance temperature detectors or resistive thermal devices (rtds), are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature. Instrumentcompany,andthetwolow-resistancethermometers (i = onohm) 9837 and 9838, from leeds and northrup,were verykindly constructed forthis investigation by mr h c dick-.
Resistance thermometer detectors the electrical resistance of metals rises as heat increases and the metals become hotter, while their electrical resistance falls as heat decreases and the metals become colder. The development of a primary laboratory for the calibration of standard platinum resistance thermometers steven armstrong henry troemner llc thorofare, new jersey usa. Transcat offers iso 17025-accredited platinum resistance thermometer calibration services for prt/sprt equipment free calibration quotes.

The thomas traceable resistance temperature detectors platinum thermometer is used for monitoring temperature in liquids, gases, refrigerators, freezers, and water baths.
A precision platinum resistance thermometer up to 660°c an article presented at ncsl in 2003  analysed the performance of a thermometer kept at 665°c for. Platinum resistance thermometers (prts) rely on the fact that platinum, like many other metals, exhibits increased electrical resistance as temperature rises for example, a conventional prt designed to provide 100 ω at 0 °c has a resistance in the neighborhood of 80 ω at -50 °c and 120 ω at 50 . Am1860/1850 standard platinum resistance thermometer user’s guide rev 201609v3 7/10 4 care and handling guidelines 1 do not subject the sprt to any physical . Sensor types: platinum resistance temperature sensor for pt-100 4 wires, alpha = 000385 environmental precision rtd handheld data logger thermometer with probe.
Common rtd sensing elements constructed of platinum, copper or nickel have a repeatable resistance versus temperature relationship (r vs t) and operating temperature range the r vs t relationship is defined as the amount of resistance change of the sensor per degree of temperature change  the . Resistance thermometers (pt100, pt1000, rtd) come in a number of forms & offer great stability, accuracy and repeatability learn about rtds or get a quote. Thermometer tube, and the cable from the thermometer head to the resistance-measuring instrument, do not enter into the resistance determination in the traditional constructions, the former or mandrel upon which the platinum wire is wound.
