1.

Minimum recommended insertion length (“u” dimension) in liquids is 4 inches and in gases is 6 inches for standard 3⁄8 × 3˝ bulb.

2.

Thermowells must be used on any application where the bulb of the thermometer may be exposed to pressure, corrosive fluids, or velocity.
Additionally, the use of a thermowell permits instrument interchangeability or recalibration without shutting down the process.

3.

When using a threaded thermowell in temperatures 750°F and above, a 3˝ lag is recommended.
