Series MP Mini-Photohelic® Differential Pressure Switch/Gage

Known for quality, reliability and accuracy, Dwyer designs and manufactures a full-line of Controllers, Data Loggers, Gages, Manometers, Monitors, Remote Displays, Switches, Transmitters, and Accessories to measure, monitor and control pressure, air velocity, flow, fan pressure, duct, and more.

Dwyer’s wide selection extends to Gages, Transmitters, Switches, Data Loggers, and Monitors for Differential Pressure. Dwyer manufactures a range of dial and digital gages to reliably measure and display pressure difference, between two pressure sources using gas or liquid in a process flow.

Dial Gages and Switches are compatible with air and other non-combustible and non-corrosive gases. Dial Gages and Dial Switches are indicators for the difference between two pressures that also have switch outputs. They can also be used for single pressure.

The Series MP Mini-Photohelic® Differential Pressure Switch/Gage combines the time proven Minihelic® II differential pressure gage with two SPDT switching set points. The Mini-Photohelic® switch/gage 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 the back of the unit.

Features

• Gage 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

Application

• Fume hoods
• Dust collection
• Pneumatic conveying
• Clean room
