Pipe Surface thermocouples are used to measure pipe temperatures upto 350 degrees C. They come in several sizes to match your pipe diameter. To obtain maximum performance, the sensors make direct contact with the pipe and they have grounded tips for a quick response. The sensors have a stainless steel pipe clamp sensor with adjustable diameter and come in thermocouple type K or J. They fit pipes with diameters ranging from 13-20 mm, 22-30 mm, 30-45 mm and 40-55 mm and have grounded tips for fast response. Fitted with 2 meters of glassfibre stainless steel braided extension cable 7/0.2 mm, the sensors are rated upto 350 degrees C.
