PSE550 is a remote sensor for measuring small differences in pressure between two sources. The sensor can function in small vacuum and positive pressure applications, detecting differential pressure from 0-2 kPa, within a -50 to 50 kPa range. PSE sensors can measure pressure of any non-corrosive, non-flammable gas. Pipe connections are made with ø4mm I.D. pneumatic tubing. An orange LED
