Resistance Temperature Detector (RTD)
A resistance temperature detector (RTD) is a precision temperature sensor that measures temperature through the predictable change in electrical resistance of a sensing element. It is suitable for reliable temperature measurement of gases, liquids and solid surfaces across a wide industrial temperature range.
Product Overview
Product Overview
Resistance Temperature Detectors (RTDs) are widely used temperature sensors. They measure temperature by detecting the change in electrical resistance of a material as temperature changes. The resistance signal can be connected directly to secondary instruments through copper conductors, providing reliable electrical output for indicators, recorders, controllers, scanners and data-acquisition systems.
RTDs can automatically measure the temperature of gases, liquids and solid surfaces over a typical range from -200°C to 500°C, and are widely used in industrial process temperature monitoring.
