LP 1000 Series

Druck Ultra Low
Pressure Sensor

The LP 1000 Series wet/wet dierential pressure
transmitter is ideally suited for use in clean room
HVAC monitoring and control. The device oers
several improvements over traditional sensors
such as user-accessible damping, excellent long­term stability, and wet/wet dierential operation
where conductive uids may be exposed to the
measurement diaphragm.

The LP 1000 Series oers a dramatic improvement
in reliability with improved stability and the ability
to tolerate condensing media. The design has been
eld proven with more than 10 years in applications
where high humidity and condensing media are a
daily occurrence. The damping adjustment feature
allows the user to slow the response time to eliminate
nuisance trips of alarms when doors are opened and
closed.

The DC version adds the ability to switch the pressure
ports to the front of the device, thus permitting
calibration to be performed from the front of the
panel, eliminating the need for additional personnel
behind the panel. Optional adjustable set-point Red
and Green Status LEDs are available.
