Pyromation RTDs – Resistance Temperature Detectors

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.

Since most RTDs have a low initial resistance, often 100 ohms, and have a small change in resistance per unit of temperature range, the resistance of the lead wire is often compensated for with a three or four wire bridge configuration built into the measuring devices. By selecting the proper elements and protective sheathing, RTDs can operate in a temperature range of (-200 to 650) °C [-328 to 1202] °F.

Pyromation manufactures RTDs for many industry applications. From single- or dual-element RTDs to PT100’s to Sanitary CIP types, we have the right sensor for your job. 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.

Pyromation Thermowells

header-thermowell

A thermowell is a pressure-tight receptacle that protects and extends the life of a temperature sensor in processing applications where the sensor is not mechanically or chemically compatible with the process environment. Installed directly into the piping systems, thermowells facilitate sensor replacement in high pressure pipelines and eliminate the need to interrupt the process flow or drain the process system for sensor maintenance functions. The use of standardized thermowells permits simple relocation of sensors throughout a plant.

Pyromation produces thermowells that have a proven track record in a wide range of industries and applications. Our product line includes threaded, Van Stone, socket-weld, weld-in and flanged thermowells. Thermowells are available as separate components or as a part of complete temperature sensor assemblies.

Temperature Sensors for the Medical Industry

  Pyromation makes precise, highly-accurate sensors used in the medical industry. Many of these assemblies are sanitary Clean-In-Place (CIP) sensors that are available with transmitters and thermowell protection and are 3-A approved. Besides being precise in temperature measurement, some of the sensors are designed for fast response times – critical in laboratories and environmental chambers. More rugged sensors are available for use in the high-temperature […]
