RTDs Versus Thermocouples TE Connectivity

WebAug 3, 2024 · A resistance temperature detector ( RTD) is typically made up of a platinum element with connected leads that is housed in a stainless-steel sheath for mechanical and electrical protection. A thermocouple is typically more mechanically resistant, but it still needs to be protected. WebThe generally accepted rule is: for temperatures below 850°C, use an RTD for accuracy; for temperatures above 850°C, use a TC. Industrial measurements typically are 200°C to 400°C, so an RTD may be the best choice in that range. Response time: While both sensors respond quickly to temperature changes, TCs are faster. WebRTD has better accuracy as compared to thermocouple but they are not suitable for high temperature applications. Thermocouple has lower accuracy but are best for high temperature measurement.

WebThe two most common ways of measuring temperatures for industrial applications are with resistance temperature detectors (RTDs) and thermocouples. The choice between them is typically determined by four factors. Temperature If process temperatures are between −200 and 500 °C (−328.0 and 932.0 °F), an industrial RTD is the preferred option. WebSize: A standard RTD sheath is 3.175 to 6.35 mm in diameter; sheath diameters for thermocouples can be less than 1.6 mm.
