Figure 20 HMP302SC Optional Sampling Cell
The numbers refer to Figure 20 above:
1 = Gas in
2 = Probe
3 = Gas out
4 = Probe
5 = Sampling cell
6 = Clamp (not needed if sampling cell is supported on the piping)
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 the DMT340 is installed in a process with a pressure differing from
the selected operating pressure at the time of ordering, please enter the
pressure value of the process into the transmitter memory, see section
Pressure Compensation Setting on page 106. Use the serial line
commands XPRES and PRES or the display/keypad. The pressure set
buttons on the motherboard inside the transmitter can also be used to set
pressure compensation.
