The accurate RTD sensor operates on the principle that metal’s electrical resistance will change in response to temperature. We offer the resistance temperature detectors that sense temperature with a high degree of accuracy, repeatability and interchangeability. An RTD element can be a wire-wound or thin film type. The wire or film is located on a ceramic or glass core. The elements of these temperature sensors are then sealed within protective capsules of ceramic or glass. A resistance temperature detector receives an excitation current across the element, and then the voltage is measured. This measurement is calculated as a temperature calibration. The broad range RTD temperature is normally -200° to 650°C (-328° to 1202°F). Platinum resistance elements are designed to supply precise and repeatable temperature.
RTD Temperature Sensors and Accessories:
We distribute the best RTD temperature sensors for excellence in laboratory and industry processes. Most RTDs have a low initial resistance, commonly 100 ohms. They also have a minimal resistance change per unit of temperature range. Because of this, a multiple wire bridge is built into the RTD to compensate for the lead wire resistance. Our standard and heavy duty resistance temperature sensing products include the following:
- Tube and wire
- Metal transition with spring strain relief
- Standard and mini plug
- Connection head
We also supply reliable RTD sensor accessories including standard and mini connectors, extension wire and connection heads.
