• Suitable for confined installation spaces

Technical Specifications

Working Principle

The pressure gauge uses a Bourdon tube sensing element to convert process pressure into mechanical movement. As pressure changes, the Bourdon tube deforms slightly, transferring motion through gears to rotate the pointer.

The internal filling liquid absorbs vibration energy generated by machinery and pressure fluctuations, helping maintain smoother pointer movement and more reliable readings.

Selection Guide

• Select a pressure range 25–50% above normal operating pressure.
• Confirm compatibility between the process media and wetted materials.
• Verify panel dimensions before choosing U-clamp mounting.
• Consider liquid-filled designs when vibration or pulsation is present.
• Choose the appropriate thread specification for installation.
• Evaluate environmental conditions and required protection levels.

FAQ

What is the benefit of a 40mm compact pressure gauge?

Smaller dial gauges are suitable for equipment with limited installation space while still providing effective pressure indication.

When should I choose a U-clamp mounting style?

U-clamp mounting is recommended when the gauge needs to be secured through a panel opening while allowing easy servicing from the rear side.

Can this gauge be used on portable machinery?

Yes. The liquid-filled construction helps withstand movement and vibration often encountered in portable or mobile equipment applications.

How often should a pressure gauge be calibrated?

Calibration intervals depend on operating conditions and industry requirements, but annual verification is generally recommended for critical applications.
