HMP368 for Pressurized Pipelines or
Moisture in Liquids
Due to the sliding fit the HMP368 is easy to install into and remove from
a pressurized process. The probe is especially suitable for measurements
inside pipelines. See section

CAUTION In pressurized processes it is essential to tighten the supporting nuts and
screws very carefully to prevent loosening of the probe by the action of
pressure.
NOTE When HMP368 is installed in a process with a pressure differing from
normal atmospheric pressure, please enter the pressure value of the
process (in bar
a
) into the transmitter memory. See sections PRES Setting
Ambient Pressure for Calculations on page 56 and Setting the Pressure for
