The 031G clamp-on design presses a sensing heat-transfer plate against the pipe using a dedicated clamping device. It serves pipe temperature measurement in petrochemical, gas and power applications. Choose K, E, J or T thermocouples, or a Pt100 RTD. The clamp is stainless steel and the terminal enclosure is a small aluminum alloy waterproof head.
