The innovative OPP-GD, is a compact wet/dry differential pressure sensor measuring both negative and positive differential pressure (bidirectional sensor). With a length less than 100 mm and a diameter less than 40 mm, the sensor can be easily mounted in limited space.
The differential pressure sensor combines efficiently two major benefits: a very robust design to sustain high static pressure in harsh environment and high sensitivity to measure minute changes in differential pressure between two points of a pressurized system. Even with a static pressure of 30 bar, the sensor can measure millibar differential pressure variations with an accuracy of 0.1%.
The intrinsically safe nature of the technology enables pressure monitoring in hazardous environment with explosive atmosphere. The fiber optic technology provides complee immunity from electromagnetic interferences, vibrations, high voltage, electrostatic surge, and lightning.
The differential pressure sensor can be delivered with an embedded temperature probe. Requiring no maintenance or calibration, the sensor is a true Plug & Forget measuring device.
