Bellows Type Differential Pressure Gauge
The Budenberg model M24 range of Differential Pressure Gauges have been designed for applications that require the measurement of low differential pressures whilst accommodating very high static pressures.
It has been designed around a balanced bellows system, which converts the differential pressure into a rotary movement by way of a torsion tube assembly and mechanical linkages. The entire assembly is liquid filled, producing a hydraulic self lubricating measurement system which allows for full line pressure to be applied to either side of the unit without damage to the device.
The M24 instrumnets are available in a range of differential ranges and static pressures and can be manufactured in a wide variety of materials, connection sizes and installation options.
