Webb15 juni 2009 · Platinum, gold, silver, tungsten, nickel, and copper have been successfully used in different RTD devices, however, platinum is superior to the other metals. It has the highest resistivity, 59 ohms per circular mil foot (Ω/cmf), a wide temperature range, good linearity, and low long-term drift.

Webb10 apr. 2024 · Basically, an RTD is a little device that measures temperature by looking at how much electricity can flow through a wire. Here’s how it works: imagine a wire made of platinum, which is a special kind of metal. As the wire heats up, the metal atoms start to vibrate more and get in the way of the flow of electricity. Webb4. Overview resistance-temperature detector (RTD) is a temperature sensor that is based on the principle of metal resistance increasing with temperature. >MetaIs used in these devices 1. platinum, which is very repeatable, quite sensitive, and very expensive, 2. nickel, which is not quite as repeatable, more sensitive, and less expensive. 5.

WebbPlatinum is the most widely used material due to its excellent stability, accuracy, and linearity.
