Platinum resistance temperature sensors (PRTs) are high-precision devices used for measuring temperature in industrial and laboratory settings. Known for their accuracy, stability, and wide temperature range (-200°C to +850°C), they are commonly used in automation, process control, and HVAC systems. PRTs operate on the principle that platinum's electrical resistance changes predictably with temperature. Common types include PT100 and PT1000 sensors, available in various forms such as thin-film, wire-wound, or probe-style configurations. Key products in this category may include industrial PRT probes, surface-mounted sensors, armored sensors for harsh environments, and calibration equipment. These sensors are essential for applications requiring reliable and repeatable temperature measurements.
