(Resistance Temperature Device): A sensor that measures temperatures with a bridge measurement (a three- or four-wire half-bridge or a four-wire full-bridge) The sensor uses materials that have a variable resistance depending on the temperature of the surrounding area and on the length of the material
An abbreviation for resistance temperature detector It is a circuit element whose resistance increases with increasing temperature in a predictable manner Platinum is the most popular material though copper, nickel, balco, and tungsten are also used in RTD's Connected via 2, 3, or 4 wire hookups
A temperature transducer that provides temperature information as the change in resistance of a metal wire element, often platinum, as a function of temperature
RESISTANCE TEMPERATURE DETECTOR: TEMPERATURE SENSOR MADE OF PLATINUM, COPPER, NICKEL OR BALCO/HITEMPCO
