dpstar RTDs are temperature sensors that contain a resistor that changes resistance value as its temperature changes. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.

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.

dpstar manufactures RTDs for many industry applications. From single- or dual-element RTDs to MT100’s 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.
