Surface Mount Temperature Transmitters

Greetings,

I'm looking for surface mount temperature transmitters. I have some pipes that I cannot insert a thermowell into. I know of the types that strap around the pipe, hose clamp style....They need to have 4-20mA out....Integral RTD to 4-20mA converter would be best because we don't have boxes in these remote locations. Just looking to see if there is something new that someone has used which I haven't seen....Thanks in advance.

Red Lion may be a source. They have lots of controllers and may have a simple transmitter.

I have used Moore Industries before for surface mount on the side of a vessel. They have a wide variety of sensors and transmitter configuration.

We often strap RTDs to the outside of pipes in a 100 bar reactor. We specify the weld pad style probe but regular 1/4" works OK. If you can use some of the thermal cement used with trace heating cable. Our process is too hot to mount the transmitter in contact so we use a remote mount, any type will work.
