MultiBoss Differential Pressure Sensor
(click on the image to enlarge)
MultiBoss®/DP Differential Pressure Transducer -- Whether you are monitoring inches of water or psi, the MultiBoss/DP does the job. Select a sensing head from one of six available ranges to suit your needs. Absolute, gage or differential pressure-- just specify the type. Powered from 12-30VDC, 4-20ma linear signal, 3-wire hookup, 35ma max current drain. Optional digital meter continuously displays the reading in 1/2" high, easy to read characters.

Housed in a 5x5x4" steel, wall mount enclosure, it has external hose barbs for easy tubing hookup. MSHA classified G, H and L for use in hazardous methane areas of underground coal mines. Compatible intrinsic safety barriers are available, along with all necessary protective regulators and accessories. The MultiBoss/DP is a high quality, US-manufactured product, combining top performance, safety and economy for your benefit.
