Differential Pressure Switch/Gage |
| Compact, Low Cost Switch/Gage |
| |
 The Series MP Mini-Photohelic differential
pressure switch/gage combines the time proven Minihelic II
differential pressure gage with two SPDT switching setpoints. The
Mini-Photohelic is designed to measure and control positive, negative,
or differential pressures consisting of non-combustible and non-corrosive
gases. Gage reading is independent of switch operation. Switching
status is visible by LED indicators located on the front and rear
of the gage. Set points are adjusted with push buttons on back
of unit. This extremely compact switch/gage is ideal for fume hoods,
dust collection, pneumatic conveying and clean room applications. Dimensional Information |
