Diaphragm sealed pressure gauges are suitable for measuring the pressure of the medium with strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, and solid floating matter. PG-05 Diaphragm sealed pressure gauge is necessary to avoid the measurement medium directly entering the general pressure instrument and prevent the accumulation of sediment and easy to clean.
Diaphragm Seal Pressure gauge working principle
The diaphragm sealed pressure gauges operates by causing a flexible membrane to deform under the exerted pressure. This deformation is transmitted to a metering medium, which will indicate pressure development. The diaphragm isolates the internal components from the pressure medium.
Applications
Diaphragm seal pressure gauge is used extensively in chemical, petroleum, pharmaceutical and food processing industries; In addition to gauges standardusage areas.

Diaphragm Sealed Pressure Gauges Features & Advantages
1. Unmatched Media Compatibility
Dual-Layer Protection: The flexible diaphragm (SS316L/PTFE/Teflon) acts as a barrier, isolating the internal mechanism from corrosive、high-temperature、high-viscosity media or substances prone to crystallization/sedimentation (e.g., acids, alkalis, pastes).
No Contamination Risk: Eliminates direct contact between the medium and the gauge, ensuring hygiene in food/pharmaceutical processes and preventing clogging in industrial pipelines.
2. Precision Engineering for Accuracy
1.0% Full Scale Accuracy: The diaphragm sealed pressure gauges equipped with a 316 stainless steel movement and glycerine-filled options (reducing vibration impact), delivering stable readings even in harsh conditions.
Wide Operating Range: Measures pressures from 0-10 MPa (customizable ranges available) with 130% overpressure protection, ensuring safety during peak loads.
3. Robust Construction for Longevity
IP65 Protection: Dust-tight and water-resistant casing (304 stainless steel) withstands harsh environments.
Temperature Resilience: Operates in -20°C to 55°C (ambient/medium), diaphragm sealed pressure gauges are suitable for both cold storage and high-temperature industrial settings.
4. User-Centric Design
Easy Maintenance: Quick-release bayonet bezel (304 stainless steel) allows hassle-free inspection and cleaning.
Clear Visibility: 4" (100mm) dial with safety glass window ensures readability from a distance.
Customizable Options: Adjustable pointers, thread types (e.g., 1/2"BSP), and OEM branding services available.
