Pressure Gauge Sourcing 80 mm, 1/2" BSP, 6 bar (model 91255AD06)

The Sourcing pressure gauge with an 80 mm dial and a 1/2" BSP threaded connection is calibrated to 6 bar for measuring and displaying fluid or gas pressure in panels and machinery. Its clear analogue dial and compact mechanical construction are suited to panel mounting and routine service tasks where visual, immediate pressure feedback is required. The gauge is designed for use in industrial installations, HVAC systems and plumbing circuits that operate within the specified pressure range.

Advantages

This model provides a large, easy-to-read 80 mm dial that improves visibility in control panels and equipment enclosures. The standard 1/2" BSP connection enables straightforward installation into existing plumbing and instrumentation lines. A mechanical movement offers reliable, maintenance-free operation without the need for power. The calibrated 6 bar range matches common low-pressure applications and replacement scenarios, and the compact bezel design supports flush or panel mounting where space is limited.

Suitable for

• Panel and machinery pressure indication in industrial environments
• HVAC system pressure monitoring and service checks
• Plumbing and water system pressure measurement
• Maintenance, inspection and field replacement tasks

Key specifications

• Dial diameter: 80 mm
• Connection type: 1/2" BSP threaded
• Pressure range: 0–6 bar (analogue)
• Display type: analogue pointer with calibrated scale
• Mounting: panel / machinery mounting (bezel design)
• Operating medium: liquids and gases compatible with gauge materials

How to use

Mount the gauge into the prepared panel cutout or threaded port using the 1/2" BSP connection and appropriate sealing material or tape to ensure leak-free installation. Orient the dial for optimal readability from the operator position and tighten fittings to the manufacturer's recommended torque values to avoid damaging the thread. After installation, pressurise the system gradually and check the gauge for correct indication and any signs of leakage. Use the gauge to monitor system pressure during normal operation and routine maintenance.

Usage recommendations

Install the gauge where it is protected from direct mechanical impact and severe vibration. Use appropriate isolation valves or syphons when measuring steam or aggressive fluids to protect the movement. Perform periodic visual checks and compare readings with a reference instrument during calibration intervals to ensure continued accuracy.
