LPM/LPX5000 Series

LPM/LPX5000 Series – Low Pressure Transmitters


This rugged design ensures high performance with long term reliability and stability.

 

Excellent thermal and long term stability characteristics make the LPX/LPM 5000 Series ideally suited to a wide range of precision applications from clean room monitoring to low level measurement, air flow in chimneys and many other low pressure measurements.

 

Features

  • Ranges from ±0.2 inH2O to ±150 psid
  • Output 2-wire, 4-20mA
  • Accuracy ±0.25% FS BSL
  • Line pressure from vacuum to 300 psi
  • Aluminum and Beryllium copper wetted material
  • Unidirectional or bidirectional
  • Variable damping from 10ms to 2 sec
  • High overpressure

Applications

The LP 1000 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 diaphragm.
The LP 1000 Series offers a dramatic improvement in reliability with improved stability and the ability to tolerate condensing media. The design has been field 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.
