Differential Pressure Gauge – Midwest 140 Series



Differential pressure is sensed by a flexible elastomer diaphragm and a calibrated range spring. The diaphragm assures total separation between the high and low pressure signals. A magnetic coupling transmits the sensing element motion to the indicating pointer. This prohibits the possibility of process fluid leaking into the gauge case, while assuring total isolation of the process fluid within the pressure capsule.

• DP Ranges from 0-25 PSID to 0-100 PSID
• Simple Rugged Designs
• Glass Reinforced Thermoplastic Gauge Front Is Standard
• Weather Resistant & Corrosion Resistant Gauge Front
• Up to 3000 PSIG Working Pressure (200 bar)

It can be use for tank level monitoring, water treatment application, filter strainer monitoring, heat exchanger pressure drop monitoring and pump performance texting
