Pressure measurement
Pressure measurement in gases
Mount the device with shutoff device above the tapping point so that any condensate can
flow into the process.

Pressure measurement in vapors
For pressure measurement in vapors, use a siphon. The siphon reduces the temperature to
almost ambient temperature. Mount the device with a shutoff device at the same height as
the tapping point.
Advantage:
only minor/negligible heat effects on the device.
Note the max. permitted ambient temperature of the transmitter!
