Wika Differential Pressure Gauge with Membrane Sensing Element

For corrosive environments with either liquid or gaseous media

These pressure gauges are designed for critical process applications requiring medium to high differential and process pressure. Gauge accuracy is ±1% of span and is excellent as an overpressure sensing element for applications with high spikes and vibration. Gauges can be used in a variety of applications and are designed for panel mounting.
Gauges have a sensor cell that houses opposed high- and low-side Monel membranes in a Halocarbon fill. As the high-pressure side moves against the membrane, the movement is transferred to a torque-tube assembly, which moves the dial on the gauge face to display pressure reading. Models 68056-44 to -56 are NACE MR-01-75 compliant and have a 316L SS sensor cell with Monel membranes, and measure differential pressures to 600 psi overpressure
