Mechanical Diaphragm Gauge - 100mm & 160mm Diameters

Mechanical diaphragm gauges with 100mm or 160mm diameters are designed for applications where the process media is highly viscous or contains solids in suspension which would block a conventional bourdon tube pressure gauge.

The design features a fixed rod from the centre of the diaphragm that rises and falls with the movement of the diaphragm. This movement directly drives the gauge pointer via a geared linkage.

There is no internal liquid fill fluid that can leak into the process medial and the design also benefits from greater stability over a fluctuating temperature range. Process connections can be either threaded or flanged and PTFE lined diaphragm wetted parts is also available.
