Precision in Low Pressure Measurement: Schaffer Diaphragm Gauges by Japsin Instrumentation
In critical industrial applications where low-pressure or vacuum measurement is essential, traditional Bourdon-type gauges often fall short. That’s where Schaffer Diaphragm Pressure & Vacuum Gauges come into play — delivering high sensitivity, accuracy, and corrosion resistance even under demanding conditions.
At Japsin Instrumentation, we manufacture and supply Schaffer Diaphragm Gauges designed for robust industrial use across pharmaceuticals, chemical processing, oil & gas, and water treatment industries.
Key Features:
- Measuring Range: From 10 mbar to 40 Bar, making it ideal for both micro-pressure and moderate-pressure applications.
- Material Options (MOC):
- SS 316 – Standard for general industrial use.
- Inconel – Exceptional resistance to high-temperature and corrosive environments.
- Hastelloy-C – Preferred for aggressive chemical handling.
- High Accuracy: Suitable for applications requiring fine measurement resolution where bourdon tubes are not reliable.
- Vacuum and Compound Ranges: Customizable options available as per user specifications.
- Dial Size: Available in 100mm and 150mm, bottom or back entry
Why Choose Schaffer Diaphragm Gauges?
Unlike conventional gauges, diaphragm gauges use a flexible membrane to sense pressure. This design is particularly effective for:
- Low pressure measurements with minimal error.
- Corrosive or viscous media where standard tubes would clog.
- Clean room or hygienic environments where oil-filled or vented gauges are unsuitable.
Industries Served:
- Pharmaceuticals & Biotech
- Chemical & Petrochemical
- HVAC & Cleanroom Monitoring
- Gas Handling Systems
- Water & Wastewater Treatment
