ClimaCheck Test plugs and sensors for “in flow” temperature measurements
The ideal location of a temperature sensor intended to measure an air or liquid temperature in a duct or a pipe is in the actual flow. Traditional sensors has been placed in so called “thermal wells” “temperature pockets” or “dip-tubes”. There are disadvantages with this solution. It is challenging to get good contact between sensor and flowing liquid/vapor and response time increase. For temperatures below freezing there is also a risk to freeze dip-tube if water condense inside. In temperature wells heat transfer fluids/paste should be used improve contact and avoid risk to freeze.
A preferred solution is to use a “test-plug” that has a membrane allowing the sensors to be inserted directly in the flow. ClimaCheck offer these together with 150 mm (6”) sensors for submersion. ClimaCheck offer these in brass as well as stainless with G 15 thread (1/2” pipe thread). Sensors are available with extended length for insulated tubes. Sensors can be removed for calibration and
re-inserted.
