Manogauge manufactures direct-acting diaphragm pressure gauges designed for corrosive, viscous or hygiene-sensitive media where a conventional Bourdon tube would become blocked or damaged by process contact.
ZX-05-1 · 0–60 kPa · ±1.6%
ZX-05-2 · 0–60 kPa · ±1.6%
ZX-04-R1 · 0–60 MPa · ±1.6%
ZX-04-R2 · 0–60 MPa · ±1.6%
ZX-01-R · 0–100 MPa · ±1.0 / 1.6%
A flexible diaphragm separates the process medium from the gauge movement. Pressure deflects the diaphragm, which transfers motion to the pointer via a linkage — keeping the medium fully isolated from the Bourdon tube and preventing blockage or corrosion of the measuring element.
Direct-acting diaphragm gauges in sizes 40–100 mm. Wetted parts in brass or stainless steel. Connection threads G, PT and NPT in 1/8 to 1/2 inch. Bottom or back connection. OEM dial artwork, custom ranges and special materials available on request.
Chemical and petrochemical dosing systems, food and beverage slurry lines, wastewater treatment, pulp and paper processes, pharmaceutical API handling and any medium that is viscous, crystallising, highly corrosive or hygiene-sensitive.
A diaphragm gauge uses a diaphragm sensing element for low pressure. A diaphragm seal isolates a standard gauge from the process medium through a sealed diaphragm assembly.
They can be configured for many corrosive media, but material and seal design must be checked against the exact medium, concentration and temperature.
