Since 1977, we at Temperature Specialists Inc. have been specializing in wire wound glass coated resistance temperature detectors (RTDs). Our expertise also extends to the manufacturing of thermocouple assemblies, custom hot wire anemometers, mold plastic parts, and miniature welding. Our temperature sensors are widely used by our customers in various industries.

At Temperature Specialists, we manufacture both standard and custom RTDs in a wide variety of sensing materials such as copper, platinum, nickel, and nickel-iron. We also produce thermocouple assemblies with different wire diameters, which allow the sensors to measure even in the smallest areas with fast time responses. Additionally, our electrical connection heads come in many materials and can be used in hazardous environments. For instance, our Bayonet style is a spring-loaded mounting for our sensors, which is excellent for use in the plastics industry.

Temperature Specialists has a wide variety of services to meet your needs, such as same-day shipping and onsite application engineers. We prioritize serving our customers and providing the best quality products. If you want more information, you can visit our website or contact one of our friendly representatives.

An RTD, resistance temperature detector, is a passive temperature sensing device that operates on the principle that the resistance of a metal changes as the temperature changes. The electrical current that passes through the element...



A thermistor, a shortened version of the term thermal resistor, is a passive component whose resistance changes as the temperature in a system changes. Thus they serve as an inexpensive, accurate, and dynamic method for measuring temperature...



A thermocouple is a transducer that converts thermal energy into electrical energy and is constructed by joining wires made from dissimilar metals to form a junction. Voltage is produced when the temperature at the junction changes...
