What is a Pipe Clamp Thermocouple?

Pipe clamp thermocouples are designed to provide continuous, accurate monitoring of outside pipe temperatures. They are especially useful where direct immersion of a probe is difficult to due to corrosive liquids, liquids under pressure or some other difficulty exists with measuring the liquid flowing through the pipes by direct means.

Suitable for pipe temperature measurement up to 1110°F. Available in thermocouple types K, T, J, N and E. Type 7 Pipe clamp thermocouples are made with a mineral insulated thermocouple and can be supplied with either an insulated or grounded thermocouple junction. Normally supplied with stainless steel conduit over PFA extension wires, although other cable options are available.

Two styles of sensor are available, the Type 7A where the clamp is fixed perpendicular to the pipe or the Type 7B which is fitted in-line to the pipe.

How are Pipe Clamp Sensors used?

Once you have decided on whether the thermocouple clamp is to be fitted at 90º to the pipe or in-line, then the clamp is simply opened around the pipe and the end is pushed into the worm-gear and then tightened with a screwdriver. The clamps are much the same as those used in general plumbing applications.

The flexible conduit can then be stowed safely and the end connected to instrumentation or a thermocouple transmitter. As standard, the sensor is supplied with stripped wires ('tails') but can be fitted with an optional thermocouple plug.

Other thermocouples for sensing pipe surface temperatures

Velcro Thermocouple for Measuring Pipe Surface Temperatures

self fastening velcro thermocoupleThese velcro thermocouples can simply be wrapped around a pipe, providing a quick and easy method of measuring the surface temperature of pipes from -150°F to +300°F.

Spring Loaded High Temperature Magnet Thermocouple

Spring loaded magnet thermocouple for surface temperature measurementsSpring loaded high temperature magnet thermocouples provide excellent surface temperature measurement between the range of 14°F to +890°F for types K, J and N (750°F max. for type T).Perfect for applications where very close contact to the surface is critical whilst maintaining the durability to withstand high temperatures.
