Diaphragm pressure gauges are vital measuring instruments for corn‑starch desanding process, used to monitor hydrocyclone feed pressure, pipeline pressure and equipment operating pressure.

Assembly consists of gauge dial, isolating diaphragm, diaphragm body, connecting flange / thread adaptor, sealing gaskets, Bourdon tube and filling fluid. The dial shows real‑time pressure readings. Diaphragm separates starch‑slurry process fluid from gauge internals and keeps particulate / corrosive ingredients out of measuring mechanism. Diaphragm body serves as mounting base and pressure‑transmission interface. Flange or threaded adapter fastens gauge onto desander, hydrocyclone or process piping; gaskets prevent medium leakage. Bourdon tube senses pressure variation and drives pointer deflection; silicone‑oil filling fluid transfers pressure and protects internal measuring elements.

In corn starch production lines, diaphragm structures are more suitable for:

Prevent Starch‑Slurry Intrusion into the pressure gauge

1. Starch slurry carries solids, fine sand and fibrous debris

2. Direct exposure would cause blockage, pointer seizure and instrument failure.

Protect the pressure gauge movement

1. Diaphragm isolates process fluid; pressure is transmitted through filling liquid

2. Mitigates corrosion, abrasion and scaling impact.

Fit for Particle‑Containing Media

1. Starch slurry contains fine sand, fibers and suspended solids

2. Diaphragm‑isolated design greatly improves instrument service life.

Convenient Cleaning & Maintenance

1. Diaphragm and sealing assemblies can be disassembled for inspection

2. Complies with cleaning requirements for food‑processing equipment.
