Axial Pressure Gauge 0 - 10 bar, 63 mm, MAN.AKS.10 B

Product detailed description

This axial pressure gauge is commonly used in residential and commercial heating systems, circulation pumps, and hot water distribution units. Installers often need to monitor pressure levels in closed-loop systems such as underfloor heating circuits, boiler circuits, and expansion vessel systems. The axial configuration allows for installation in tight spaces where side-mounted gauges would interfere with adjacent piping. The 63 mm dial size ensures clear visibility from a distance, making it suitable for installations in mechanical rooms or behind control panels.

The gauge is particularly useful for monitoring pressure fluctuations in systems with variable flow rates or where pressure regulation is critical. It is commonly found in systems using circulators, heat exchangers, and expansion vessels. The rear connection design simplifies mounting on pipes or fittings where space is limited, and the ABS housing resists corrosion and mechanical damage in typical operating environments.

The 0-10 bar range is appropriate for most domestic and light commercial heating and water systems, where pressure deviations are typically within this span. The accuracy class 2.5 indicates that the maximum allowable deviation is ±2.5% of the full scale, which is acceptable for routine monitoring but not for precision calibration tasks. The 63 mm dial size is selected for readability in environments with ambient lighting and moderate distances between the gauge and the operator. The rear 1/4 inch thread allows secure connection to standard pipe fittings without requiring additional adapters or unions.

Installation and connection

To install the gauge, first confirm the system is depressurised and the area is accessible. Use a suitable wrench to connect the gauge to the fitting using the 1/4 inch rear thread. Ensure the sealing washer or tape is applied to prevent leaks. The axial orientation should be aligned so that the face of the gauge is visible and not obstructed by adjacent components. Key checkpoints include verifying the correct thread direction (right-hand), ensuring the sealing surface is clean and free of debris, and confirming the gauge is mounted perpendicular to the line of sight for accurate reading. Common installation mistakes include using incompatible sealing materials, over-tightening the connection, and failing to align the gauge for optimal visibility. These errors can lead to measurement inaccuracies or damage to the gauge housing.

Compatibility and accessories

This gauge is compatible with standard pipe fittings and valves using 1/4 inch threads. It is typically used alongside pressure-reducing valves, expansion vessels, and circulation pumps in closed-loop systems. When installing in high-vibration environments, consider using a mounting bracket or vibration-dampening pad to prevent mechanical stress on the Bourdon tube. No additional accessories are required unless specified for the specific application.

Technical background for designers

The gauge operates on the principle of a Bourdon tube, which bends in response to internal pressure. As pressure increases, the tube straightens, moving the pointer across the dial. The ABS body provides a lightweight yet durable housing, while the acrylic cover protects against dust and minor impacts. The aluminium dial and pointer offer a clear, contrast-rich display that remains legible under various lighting conditions. The rear connection minimises protrusion from the mounting surface, making it ideal for compact installations. The gauge is designed for non-aggressive media such as water and glycol mixtures. Long-term exposure to high temperatures or aggressive chemicals may affect the integrity of the materials, particularly the sealing components. For optimal performance, ensure the gauge is installed in a location where it is not subject to direct sunlight or extreme temperature variations.

Service and operation

Regular visual inspections are recommended to check for signs of physical damage, such as cracks in the acrylic cover or deformation of the housing. If the pointer does not return to zero when the system is depressurised, the gauge may require recalibration or replacement. No scheduled maintenance is specified in the technical documentation, but any suspected malfunction should be addressed promptly to avoid inaccurate readings.

Frequently asked questions

Can this gauge be used in a solar thermal system?
Yes, provided the system uses water or glycol and the operating pressure remains within the 0-10 bar range. The ABS housing and Bourdon tube are suitable for typical solar system conditions.

Is the rear connection compatible with copper pipe fittings?
Yes, the 1/4 inch thread is a standard size for copper pipe fittings. Ensure the connection is sealed with appropriate materials to prevent leaks.

Can the gauge be mounted horizontally?
Yes, the axial orientation allows for horizontal mounting. However, the face of the gauge should remain perpendicular to the viewer’s line of sight for accurate reading.

Does the gauge require recalibration after installation?
No, the gauge does not require recalibration after installation unless it shows signs of inaccuracy or damage during operation. The accuracy class 2.5 is maintained under normal conditions.
