This clip-on temperature sensor is perfect for refrigerants and hydronics fluids. The sensor probe clips onto existing pipe work without drilling. The sensor element is housed in a copper tube with a slightly curved surface to make intimate thermal contact with the pipe. The sensor reacts to changes in the fluid temperature quickly, on the order of 5 seconds for copper pipe.

The stainless spring clip makes for quick installation on either 1/2 inch or 3/4 inch pipes. The sensor cable is 3 meters long and consists of 24 AWG stranded copper wire. The high temperature rated rubber coating  is durable but also flexible for easy handling and routing. The cable is rated to  UL2651 (105 DegC) and the listing can be found in the online UL registry under file number UL42323.

Typically, our stock consists of 10k type 3 sensors, 10k type 2 sensors, and 1k Pt sensors. If you require different sensor curves, please contact us though we will ask for an MOQ of 100 pcs or so.
