Industrial RTD (PT100) Probes

Thermal Detection manufacture a comprehensive range of high quality temperature probes for industrial process and plant monitoring. We have over 30 years experience in the design and manufacture of Resistance Temperature Detectors (also known as RTD probes, PRT probes or PT100 and PT1000 probes), and we can help you to navigate through the range of options.  

RTD's are based on the properties of certain metals where a change in temperature causes a measurable change in the electrical resistance of the material. The most common material used to make RTD sensors is Platinum. A PT100 sensor, generally the most common type, is a Platinum sensor which reads 100 Ohms at 0⁰C, and exhibits a positive resistance change to increasing temperature. Different tolerance classes are available which dictate the accuracy of the reading (Class B, A, AA as IEC 60751:2008, also 1/10 DIN).

Highly accurate and stable temperature measurement can be achieved using RTD temperature probes, with consideration to a number of key design criteria such as sensor type, tolerance class and wiring options. The FAQ page provides additional information.
