Tube & Wire RTD's

Resistance Temperature Detectors Ensure Percise Repetable Temperature Measurement

Resistance temperature detectors (RTDs), also known as resistance thermometers, accurately sense process temperatures 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 measurement 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.  By selecting the proper elements and protective sheathing, RTDs can operate in a temperature range of -200 to 650°C (-328 to 1202) °F.

Adjustable Bayonet Spring

Adjustable spring style RTD's bend to any angle to fit a wide range of hole depths, eliminating the need to stock numerous styles. Optional stainless steel over-braid can offer additional lead protection in demanding applications.
