Series MP Mini-Photohelic Differential Pressure Switch/Gauge
Brand: Dwyer Instruments, LLCThe Series MP Mini-Photohelic® differential pressure switch/gauge combines the time proven Minihelic® II differential pressure gauge with two SPDT switching set points.
The Mini-Photohelic® switch/gauge is designed to measure and control positive, negative, or differential pressures consisting 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 gauge.
Set points are adjusted with push buttons on back of unit.
Features- 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
