Case/Housing Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A precision-engineered enclosure designed to protect the delicate internal components of pressure gauges and sensors from external contaminants, mechanical damage, temperature fluctuations, and corrosive environments. It maintains structural integrity under varying pressure conditions while allowing for proper pressure transmission and visual/electronic interface access.

Working Principle

The housing creates a sealed or vented protective barrier around the pressure sensing element. It transmits external pressure through ports or diaphragms to the internal mechanism while isolating it from environmental factors. Materials and design are optimized to minimize stress concentration, prevent deformation under pressure, and maintain calibration accuracy.

Materials

Stainless steel (AISI 304/316), aluminum alloys (6061-T6), brass (C36000), engineered plastics (polycarbonate, ABS, PPS), with corrosion-resistant coatings and seals (EPDM, Viton, silicone).

Frequently Asked Questions

What is the difference between vented and sealed pressure gauge housings?

Vented housings allow atmospheric pressure reference and prevent condensation, while sealed housings provide complete environmental protection for applications with contaminants or submersion risks.

How does housing material affect pressure measurement accuracy?

Material thermal expansion coefficients and stiffness impact dimensional stability under temperature changes and pressure loads, affecting calibration drift. Stainless steel offers best stability for precision applications.
