LPM/LPX 1000
The LP 10 0 0 Series wet/wet differential pressure
transmitter is ideally suited for use in clean-room
HVAC monitoring and control. The device offers
several improvements over traditional sensors such
as user accessible damping, excellent long term
stability, and wet/wet differential operation where
conductive fluids may be exposed to the
measurement diaphragms. For applications where
the pressure transmitter will be installed within one
of the pressure zones, the LPM/LPX 1000 is
available in a wet/wet gauge pressure configuration
where the second pressure port is eliminated,
venting the sensor directly to the atmosphere.
The LP 10 0 0 Series offers a dramatic improvement
in reliability with improved stability and the ability
to tolerate condensing atmospheres. The design
has been field proven for more than 10 years in
applications where high humidity and condensing
atmospheres are daily occurrences. The damping
adjustment feature allows the user to slow the
response time to eliminate nuisance trips of alarms
when doors are opened and closed.
