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!
