China The Application Pressure Gauge Shows How Much Air Pressure You Factories & Factory

An application pressure gauge measures the elastic deflection of an internal sensing element (Bourdon tube or diaphragm) exposed to factory air line pressure. As compressed air enters the gauge connection, it exerts force against the internal wetted area. The resulting movement rotates a mechanical pointer across a calibrated dial face (indicating values in Bar, PSI, or kPa). By installing gauges at critical line junctions—such as compressor outlets, air receivers, filter regulators, and end-user pneumatic machinery—facility managers receive instant visual verification of line pressure, helping detect line resistance, leaks, or compressor degradation.

Dry pressure gauges contain air inside their housing and are designed for static, low-vibration environments like standard pneumatic control panels. Oil-filled pressure gauges (filled with food-grade glycerin or industrial silicone fluid) submerge the internal pointer mechanism. The liquid dampens intense mechanical vibrations and pressure surges from equipment like piston compressors or hydraulic pumps, prevents pointer flutter, lubricates moving gears, and stops internal moisture condensation.

Brass offers exceptional machinability, cost efficiency, and excellent corrosion resistance when exposed to non-corrosive media such as clean dry air, nitrogen, or inert gases. However, aggressive chemicals, high-moisture steam, or ammonia rapidly corrode copper alloys. 316 Stainless Steel contains molybdenum, granting superior resistance to pitting, acids, and harsh industrial environments, making it mandatory for petrochemical, marine, and pharmaceutical applications.

Under standard industrial operating protocols (ISO 9001 / ISO 17025), pressure gauges should undergo recalibration once every 12 months. However, for high-cycle critical processes, severe vibration environments, or safety-critical applications (such as medical gas or boiler pressure monitoring), bi-annual (6-month) calibration intervals are recommended to verify accuracy within standard Class 1.0 or Class 1.6 limits.

Yes. Huzhou Accuracy Instrument Co., Ltd. provides full OEM/ODM engineering customization. We can print your company logo directly onto the dial face, produce dual or triple customized scales (e.g., Bar/PSI/Kg/cm²), and supply any standard or specialized process connection, including NPT, BSP, BSPT, Metric (M20x1.5), or sanitary tri-clamp fittings.

High-pressure instruments feature solid-front safety baffles and blow-out back disks compliant with EN 837-1 / ASME B40.100 standards. In the event of an accidental Bourdon tube rupture under extreme overpressure, the internal pressure discharges safely out the back of the case away from the operator, rather than shattering the front glass window.
