品 与 服 务LPM/LPX1000 Series
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, byventing the sensor directly to the atmosphere.The LP 1000 Series wet/wet differential pressure transmitter is ideally suited for use in clean-room HVAC monitoring and control.
