Resistance temperature detectors (RTD) accurately sense temperature with an excellent degree of repeatability and interchangeability of elements. The RTD is composed of certain metallic elements whose change in resistance is a function of temperature. In operation, a small excitation current is passed across the element, and the voltage, which is proportional to resistance, is then measured and converted to units of temperature calibration. The RTD element is manufactured by winding a wire (wire wound elements) or plating a film (thin film elements) on a ceramic or glass core and sealing the element within a ceramic or glass capsule.
| Spec 1 | From single- or dual-element RTDs to PT100's to Sanitary CIP types, we have the right sensor for your job. |
|---|---|
| Spec 2 | RTDs can operate in a temperature range of (-200 to 650) °C [-328 to 1202] °F. |
| Spec 3 | If what you need is not available from our catalog, our product engineers will design an RTD for your specific application, including temperature sensor assemblies that require connection heads, thermowells and/or transmitters. |
