PM/LPX 1000 LPM/LPX 1000 Series Ultra Low Differential Pressure Transmitter ! Ranges: 0.1 to 6 inH20 ! Accuracy: 0.5% FS BSL (0.25% FS optional) ! NIST calibration certificate option ! Gauge or wet/wet differential pressure ! User accessible damping ! Unidirectional or bidirectional operation ! Current or voltage output ! Optional local display 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 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 1000 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. !"
