Differential Pressure Manometer DIR 100/160 Series

Differential pressure meters of the DIR type with two tube springs are used for simultaneously measuring two different pressures, with direct indication of the differential pressure ∆p. They consist of two tube spring systems that work independently of one another. Each system has its own pressure connection, labelled with + and -. Both types of pressure are transmitted to a double meter with concentric needle shafts. The pressure are indicated via a scale dial and an indicator.

Features:

• round housing ng 100 and 160 mm for chemical use
• differential pressure Δp can be directly read off
