SF6 GAS DENSITY MONITOR, 0-1.0 MPa Absolute Pressure Range, Class 1.0 Accuracy, Temperature Compensated, 304/316L Stainless Steel, IP Rated

SF6 GAS DENSITY MONITOR, 0-1.0 MPa Absolute Pressure Range, Class 1.0 Accuracy, Temperature Compensated, 304/316L Stainless Steel, IP Rated

This three-color density relay is a precision measuring device designed for SF6 gas, operating at 20°C with a class 1.0 MPa absolute rating. It features clear pressure indication through a three-color panel, enabling intuitive status recognition.

Core Specifications

Visual Indication

The panel uses three color-coded zones to reflect pressure status:

• Red zone: 0 - 0.60 MPa absolute (abnormal pressure)
• Yellow zone: 0.60 - 0.62 MPa absolute (warning pressure)
• Green zone: 0.62 - 1.0 MPa absolute (normal pressure)

Key Performances

• Sealing Performance: Verified by helium leak detection
• Insulation Performance: Withstands 2kV power frequency voltage at 50Hz for 1 minute; excellent insulation resistance
• Environmental Adaptability: Oil-free and oil-filled options available; strong shock and anti-vibration resistance
• Temperature Compensation: Equipped with bimetal temperature-sensitive element and temperature compensation sheet for stable operation under varying ambient temperatures

Materials & Interfaces

• Casing & Connector: 304 stainless steel for corrosion resistance
• Pressure-Sensitive Element: 316L bourdon tube ensuring measurement accuracy
• Watch Glass: Safety glass for clear observation and protection
• Anti-Vibration Fluid: Silicone oil to enhance stability
• Driving Mechanism: Stainless steel for durability
• Pressure Connection Port: Standard interface for easy installation
