Clamping to the outside of a pipe, this strap on temperature sensor reads fluid temperature through the pipe wall with a 10,000 ohm Type II thermistor, and needs no thermowell, no shutdown and no penetration. A worm-drive clamp draws the sensing surface tight against the pipe wall. A galvanized enclosure houses the terminations, which suits retrofit work on a system that cannot be drained.

Surface mounting trades a little accuracy for a great deal of access. Because the element reads through the pipe wall rather than the fluid, the response is slower than an immersion sensor and the reading is affected by ambient air, so pipe insulation over the sensor matters as much as the sensor itself. In return there is nothing to drain, nothing to shut down and no fitting to weld, which is why this series is the usual answer on an existing hydronic loop.
