The following numbers refer to Figure 12 on page 30:
1 = Probe
2 = Clasp
nut
3 = Pen
4 = Fitting
screw
NOTE Take care not to overtighten the clasp nut to avoid difficulties when
opening it.
CAUTION Take care not to damage the probe body. A damaged body makes the
probe less tight and may prevent it from going through the clasp nut.
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 HMT318 is installed in a process with pressure differing from
normal atmospheric pressure, please enter the pressure value of the
process (in hPa or mbar) into the transmitter memory via the serial line
(see section PRES Set Ambient Pressure for Calculations on page 48).
