Performance Description of DAITO KEIKI S11-4-2 SUS316 Pressure Gauge

1. Model Code Definition

• AU: All-stainless standard corrosion-resistant series by DAITO, back axial mounting design

• G3/8: Standard parallel pipe connection thread

• ?100: 100mm large dial for superior readability

• 0.5MPa / 5kgf/cm2: Dual-scale measuring range

• SUS316: SUS316 stainless steel wetted material for corrosive service environments

2. Core Technical Parameters

• Dual graduation in MPa and kgf/cm2 conforms to Japanese & domestic industrial reading standards, delivering accurate measurement for low-pressure applications.

• Accuracy complies with JIS B7505 Japanese Industrial Standard; standard precision ±1.6%FS to satisfy routine equipment pressure monitoring, on-site inspection and commissioning requirements.

• ?100mm oversized dial with clear, evenly spaced graduations enables quick reading even from long distance or elevated installation positions and minimizes visual reading error.

• G3/8 parallel thread boasts universal compatibility with most hydraulic, water, pneumatic and chemical piping, featuring reliable sealing against leakage and loose connection.

3. Anti-corrosion & Durability Advantages

• Excellent chemical resistance: Resists erosion from weak acid, weak alkali, brine and humid corrosive process fluid to prevent rusting, bore clogging and premature component failure, suitable for chemical plants, water treatment, seawater service and damp production workshops.

• Superior fatigue resistance: Stable elastic property of SUS316 material prevents elastic fatigue, zero drift and reading deviation under repeated cyclic low-pressure load for long-term continuous operation.

• Fully enclosed stainless steel housing provides dustproof and anti-oxidation protection for indoor and open-air equipment installation.

4. Environmental Compatibility & Operational Stability

• 0~0.5MPa is a widely adopted low-pressure span for general water, air, low-pressure hydraulic and HVAC systems with sufficient overpressure margin to avoid accidental gauge damage.

• Standard dry non-filled version works at ambient temperature ranging from -20℃ to 80℃ with minimal reading fluctuation under varying temperature; glycerine-filled dampened option is available for vibrating piping and pulsating pressure conditions.

• Precision original DAITO movement delivers smooth pointer operation without jitter or sticking; highly sensitive to subtle low-pressure changes with reliable real-time pressure indication and low maintenance downtime.

5. Protection & Safety Features

• Fully sealed dust and drip-proof enclosure blocks dust and moisture ingress to avoid internal movement rust and seizure for consistent long-term performance.

• Entirely mechanical construction free of electric wiring and components, achieving intrinsic safety for general hazardous industrial areas with no fire or electric leakage risk.

• Robust SUS316 Bourdon tube withstands transient mild overpressure without deformation or rupture, far safer than ordinary brass-bodied pressure gauges.
