Installation examples
A-B In pipes with a small cross section the thermowell tip should reach or extend slightly past the center line of
the pipe (=L).
C-D Angled installation.
The immersion length of the thermometer influences the accuracy. If the immersion length is too
small then errors in the measurement are caused by heat conduction via the process connection and
the container wall. If installing into a pipe then the immersion length should be at least half of the
pipe diameter. A further solution could be an angled (tilted) installation (see C and D). When
determining the immersion length all thermometer parameters and the process to be measured
must be taken into account (e.g. flow velocity, process pressure).
• Installation possibilities: Pipes, tanks or other plant components
• Recommended minimum immersion length: 80 to 100 mm (3.15 to 3.94 in)
The immersion length should correspond to at least 8 times of the thermowell diameter. Example:
Thermowell diameter 12 mm (0.47 in) x 8 = 96 mm (3.8 in). A standard immersion length of
120 mm (4.72 in) is recommended.
• ATEX certification: Always take note of the installation regulations!
