Dwyer MP Mini-Photohelic® Differential Pressure Gauge

The Series MP Mini-Photohelic® differential pressure switch and gauge is based on the time proven design of the Minihelic® II differential pressure gauge, but it also features two SPDT switching set points. The Mini-Photohelic switch and gauge is designed to measure and control positive, negative, or differential pressures of non-combustible and non-corrosive gases. Gauge reading is independent of switch operation. Switching status is visible by LED indicators located on the front and rear of the gage. You can adjust the set points with push buttons on the back of the unit.

• Gauge reading unaffected by switch operation and will continue to read pressure even during power loss
• Visible switch status LED provides indication of set point switching state
• Compact design but with the power of larger devices can meet the same application specifications
• 24 VDC power
• For use on fume hoods, dust collection, pneumatic conveying, and clean rooms
