What is a Compound Gauge?
A compound gauge is a specialized pressure measuring instrument capable of measuring both vacuum and positive pressure on the same dial. Unlike conventional pressure gauges that only measure positive pressure, a compound gauge allows operators to monitor systems that may operate below atmospheric pressure as well as above atmospheric pressure.
This capability makes compound gauges extremely useful in industries where processes involve suction, vacuum generation, pumping, filtration, refrigeration, and pressure control systems.
The Ji Japsin Industrial Compound Gauge provides seamless monitoring across both pressure zones, ensuring better operational control and process visibility.
Pressure Range -1 to 7 Kg/Cm²
This industrial compound gauge is calibrated with a measuring range of:
- Vacuum: -1 Kg/Cm²
- Positive Pressure: 0 to 7 Kg/Cm²
This range allows the gauge to monitor both negative and positive pressure conditions effectively.
The pressure range is ideal for applications involving:
- Vacuum pumps
- Air compressors
- Filtration systems
- Water treatment plants
- Hydraulic equipment
- Chemical processing systems
- Pneumatic systems
- Industrial machinery
The broad measuring range makes it a versatile instrument suitable for numerous industrial processes.
Dual Scale Reading for Global Applications
The gauge features a convenient dual-scale dial:
Primary Scale
- -1 to 7 Kg/Cm²
Secondary Scale
- -30 InHg to 100 PSI
This dual-scale configuration enables operators to view readings in both metric and imperial units without requiring conversions.
Benefits of Dual Scale Display
- Easy pressure interpretation
- Faster process monitoring
- Reduced reading errors
- Suitable for international equipment
- Improved operator convenience
The clear and highly visible scale markings enhance operational efficiency and improve monitoring accuracy.
High Accuracy – ±1% Full Scale Deflection
Accuracy is a critical requirement in industrial pressure measurement. This compound gauge provides ±1% Full Scale Deflection (FSD) accuracy, ensuring reliable and repeatable readings.
Advantages of High Accuracy
- Better process control
- Enhanced system safety
- Improved equipment protection
- Reliable performance monitoring
- Reduced operational risks
- Increased process efficiency
Accurate measurement allows maintenance teams and operators to identify system abnormalities before they lead to costly failures.
Glycerin Filled for Enhanced Performance
One of the major advantages of this gauge is its glycerin-filled construction.
The glycerin filling acts as a damping medium that minimizes pointer fluctuation caused by vibration and pulsating pressure.
Benefits of Glycerin Filling
- Reduced needle vibration
- Improved reading stability
- Better visibility of measurements
- Protection against internal wear
- Extended instrument lifespan
- Enhanced performance in harsh environments
Glycerin-filled gauges are widely preferred in industrial facilities where equipment vibration and pressure pulsations are common.
Large 4-Inch Dial for Easy Readability
The gauge features a 100 mm (4-inch) dial, providing excellent visibility and readability.
Benefits of Large Dial Size
- Easy monitoring from a distance
- Reduced reading errors
- Faster operator response
- Improved process visibility
- Suitable for industrial environments
The large dial allows personnel to quickly verify system conditions without approaching the instrument closely.
Surface Mounting Design
This model is designed for surface mounting, making it ideal for control panels, machine assemblies, instrumentation panels, and process systems.
Advantages of Surface Mounting
- Easy installation
- Secure positioning
- Improved accessibility
- Better operator visibility
- Professional equipment appearance
Surface-mounted gauges are commonly used in industrial installations where centralized monitoring is required.
Bottom Entry Configuration
The bottom entry design allows the process connection to be installed directly from the rear lower side of the gauge.
Benefits
- Simplified installation
- Compact arrangement
- Better dial positioning
- Reduced piping complexity
- Common industrial standard
This mounting style is particularly useful for panel-mounted and equipment-mounted installations.
Standard 3/8″ NPT Connection
The gauge is equipped with a 3/8″ NPT threaded connection, ensuring compatibility with standard industrial piping systems.
Connection Benefits
- Easy integration
- Secure sealing
- Leak-free operation
- Standard industrial compatibility
- Simplified maintenance
The NPT connection is widely used across industrial sectors and provides dependable installation performance.
