Technical details and manufacturing context for Pressure Gauge

Definition
This pressure gauge is a monitoring component for the Continuous Starch Hydrocyclone Separator. It provides real-time visual feedback on the internal pressure of the hydrocyclone unit, which is essential for ensuring optimal separation efficiency of starch from other components, maintaining process stability, and preventing equipment damage due to overpressure conditions. The gauge is designed for food manufacturing environments, with wetted parts made of 316L stainless steel and a case of 304 stainless steel for corrosion resistance and hygiene. The window is made of polycarbonate for impact resistance. The measuring range is 0–1.6 MPa with an accuracy class of 1.6 per EN 837-1. The dial diameter is 100 mm, and the process connection is a G1/2 male thread, bottom mount. The operating temperature range is -20 to 60 °C, and the ingress protection rating is IP65 per IEC 60529. The approximate weight is 0.5 kg. This gauge is intended for use in starch hydrocyclone systems, but model-specific values and standards must be verified with the legal manufacturer or supplier before procurement or installation.
Working Principle
The pressure gauge typically uses a Bourdon tube, diaphragm, or capsule mechanism. Pressure from the hydrocyclone's fluid stream acts upon this sensing element, causing it to deform elastically. This mechanical deformation is translated, via a linkage and gear system, into the rotational movement of a pointer on a calibrated dial, providing a direct pressure reading. The gauge is designed to withstand typical operating pressures and provide accurate readings within the specified range.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Bourdon tube fatigue/fracture
Cause: Cyclic pressure fluctuations exceeding design limits, leading to metal fatigue and eventual rupture.
Pointer sticking or erratic movement
Cause: Contamination ingress (moisture, particulates) or mechanical wear in the gear mechanism, causing binding or slippage.
Maintenance Indicators
  • Pointer stuck at zero or maximum despite system pressure changes
  • Visible fluid leakage or condensation inside the gauge glass
Engineering Tips
  • Install a pulsation dampener or snubber to reduce pressure spikes and cyclic stress on the Bourdon tube
  • Use diaphragm seals or chemical seals when measuring corrosive or slurry media to prevent direct contact with internal components
