Model 109 Differential Pressure Bourdon Tube Type Gauge & Switch
Brand: Mid-West InstrumentThe Model 109 is a precision differential pressure gauge capable of working in systems requiring medium to high differential pressure readout. 
A test quality bourdon tube assembly is used to sense the differential pressure. 
The assembly is encapsulated in a high pressure chamber that is fitted with a pressure connection to the inside of the bourdon tube and a second connection to the pressure chamber.
