Pressure Gauges and Adapters

Pressure gauges in hydraulic systems

Hydraulic pressure gauges indicate the actual system pressure and are essential for commissioning, monitoring and maintenance. Depending on the application, different dial ranges, accuracy classes and mounting styles (radial or back entry) are used.

Test points, adapters and test couplings

To connect gauges permanently or temporarily, suitable adapters and test points are required:

• gauge adapters to match thread types and mounting positions
• test couplings (test points) for connecting test gauges under pressure
• tees and manifolds for adding measuring points to existing circuits
• hose and quick-coupling adapters for mobile test equipment

Typical applications

• pressure monitoring on pumps, cylinders and valve blocks
• fault finding and diagnostics in hydraulic circuits
• test benches and service tools
• long-term monitoring of critical functions in industrial plants

Selecting the right gauges and adapters

When choosing pressure gauges and adapters, consider:

• required pressure range and scale graduation
• accuracy class and damping (for example glycerine filled)
• connection thread, mounting position and necessary adapters
• hydraulic fluid, temperature range and environmental conditions
