Budenberg M24 Bellows Type Differential Pressure Gauge

Product Description

The Budenberg M24 Bellows Type Differential Pressure Gauge has been designed for applications which require the measurement of low differential pressures whilst accommodating very high static pressures. 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. Instruments 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. We have an interesting article relating to Pressure Gauge Selection in the Technical section on this website.

Designed and manufactured in the UK.
