Pressure Gauge

Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Pressure Gauge used in the Food Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Pressure Gauge is characterized by the integration of Bourdon Tube / Sensing Element and Movement (Linkage & Gear). In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel (Case & Internals) construction to support stable, high-cycle operation across diverse manufacturing scenarios.

A measuring instrument that monitors and displays the pressure within the Continuous Starch Hydrocyclone Separator system.

Technical details and manufacturing context for Pressure Gauge

Definition
A pressure gauge is a critical monitoring component of 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.
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.
Common Materials
Stainless Steel (Case & Internals), Tempered Glass (Lens), Brass/Bronze (Fittings)
Technical Parameters
  • The pressure range the gauge is designed to measure, typically selected to match the operating pressure of the hydrocyclone separator. (MPa or bar) Customizable
Components / BOM
  • Bourdon Tube / Sensing Element Part
    Converts applied fluid pressure into proportional mechanical displacement.
    Material: Phosphor Bronze, Beryllium Copper, or Stainless Steel
  • Movement (Linkage & Gear) Part
    Amplifies and transfers the small displacement from the sensing element to the pointer shaft.
    Material: Steel, Brass
  • Pointer & Dial Part
    Indicates the measured pressure value on a calibrated scale.
    Material: Aluminum (Dial), Steel/Plastic (Pointer)
  • Case & Lens Part
    Protects internal mechanisms from the environment and provides a viewing window.
    Material: Stainless Steel / Plastic (Case), Tempered Glass / Polycarbonate (Lens)
  • Connection Socket Part
    Provides the threaded interface for mounting the gauge to the hydrocyclone's pressure tap.
    Material: Brass, Stainless Steel
