Axial Pressure Gauge 0 - 6 bar, 63 mm, Hydroland MAN.AKS.6 B

Product detailed description

Pressure monitoring is a critical task in the installation and maintenance of heating, plumbing, and pump systems. Whether working on boiler circuits, circulation pumps, or water supply lines, technicians need reliable instruments to measure and verify pressure levels. This axial pressure gauge provides a compact solution suitable for a wide range of applications, including closed-loop systems and pump groups where pressure fluctuations are common. Its robust design ensures accurate readings even in environments with moderate vibration and temperature variations.

Installers typically use such gauges in commercial and residential buildings, industrial facilities, and agricultural irrigation systems. The axial orientation allows for space-saving mounting on panels or pipe walls, making it ideal for tight spaces. The 63 mm dial size offers good visibility without excessive bulk, while the rear connection simplifies installation behind panels or within enclosures.

The 0-6 bar measurement range makes this gauge suitable for systems where pressure exceeds the 4 bar variant. The 63 mm dial size ensures sufficient readability in standard working distances. The accuracy class of 2.5 means the maximum permissible deviation is ±2.5% of the full scale, which is acceptable for general monitoring tasks but not for precision control. The ABS housing and acrylic window provide protection against dust and light impact, while the aluminium dial ensures long-term readability under normal conditions.

Installation and connection

To install the gauge, first ensure the system is depressurised and disconnected from power. Use a suitable wrench to fit the 1/4 inch rear threaded connection securely to the pipe or valve port. The axial orientation requires alignment of the dial with the viewing angle, ensuring the gauge is mounted in a position where it can be easily read during routine checks. A common mistake is over-tightening the connection, which can damage the threads or cause leaks. Always verify the seal with a suitable gasket or thread tape if required by the system specifications. After installation, check for any air bubbles or blockages in the line that could affect the reading.

Compatibility and accessories

This pressure gauge is compatible with most heating and pump systems that use standard 1/4 inch threaded connections. It is commonly used alongside pressure switches, expansion vessels, and circulation pumps in closed-loop systems. For systems requiring remote monitoring or digital integration, additional transducers or signal converters may be necessary. No specific accessories are required for basic installation, though a mounting bracket might be useful in some panel configurations.

Technical background for designers

The gauge operates using a Bourdon tube mechanism, where internal pressure causes the tube to deflect, moving the pointer along the aluminium dial. The ABS housing provides a lightweight yet durable enclosure, while the acrylic window protects the dial from physical damage. The rear connection allows for a compact footprint, making it suitable for panel mounting. Longevity and accuracy depend on proper installation, avoiding exposure to extreme temperatures or mechanical shocks. The gauge should be installed in a location free from direct sunlight and excessive vibration to prevent premature wear.

Service and operation

Routine maintenance involves visually inspecting the gauge for cracks, leaks, or signs of corrosion. The acrylic window should be kept clean for consistent readability. The manufacturer provides a 2-year warranty, covering defects in materials and workmanship. If the gauge shows irregular readings or fails to respond to pressure changes, it should be removed and tested using a calibrated reference device. There are no scheduled service intervals specified in the technical documentation, and disassembly for cleaning is not recommended due to the risk of damaging internal components.

Frequently asked questions

Can the gauge be mounted horizontally?
Yes, the axial design allows for horizontal or vertical mounting depending on the available space and viewing requirements.

Is the gauge suitable for steam systems?
No, the gauge is designed for liquid media only. Exposure to steam could cause damage to the internal components.

Can the gauge be used in outdoor installations?
It is not recommended for direct outdoor use without protective housing, as the acrylic window and ABS housing are not weatherproof.

Does the gauge require regular calibration?
Calibration is not specified in the technical documentation. However, if accuracy becomes questionable, a certified calibration service should be used.
