Pressure gauge - axial, D 50, 0 - 10 bar

Product detailed description

Axial pressure gauges are essential components in central heating, plumbing, and irrigation systems where continuous monitoring of fluid pressure is required. Installers commonly use these devices in residential, commercial, and industrial buildings to ensure proper system operation and identify potential issues such as blockages or leaks. This gauge is particularly suited for applications involving water or compatible fluids, where accurate pressure readings are critical for system performance and safety.

In typical installations, the device is mounted near the control panel or directly on the pipe system to allow easy access for reading and inspection. It is frequently found in boiler circuits, circulation pumps, and expansion vessel systems. The compact design and rear-mounted connection make it ideal for tight spaces and concealed mounting behind panels or within cabinets.

Installation and connection

To install the pressure gauge correctly, align the rear 1/4 inch male thread with the corresponding female fitting on the system piping. Use a sealing compound or Teflon tape to prevent leakage. Ensure the gauge is mounted vertically and in a location free from vibration and direct sunlight. Before tightening the connection, verify that the system is depressurised and the thread is fully engaged. Common installation errors include misalignment, over-tightening, which can damage the internal mechanism, and using incompatible sealing materials that may degrade under operating conditions.

Compatibility and accessories

This pressure gauge is designed to work with standard hydraulic systems that operate within the specified pressure range. For a secure fit, a sealing compound or Teflon tape is recommended. When integrating into a larger system, ensure that the mounting space allows for the 50 mm dial size and that the orientation does not obstruct access to the scale. No additional accessories are required unless specified for the particular application.

Technical background for designers

The axial pressure gauge operates based on the deformation of a Bourdon tube or diaphragm under pressure. As pressure increases, the sensing element deflects, moving a pointer across a calibrated scale. Constructed from durable materials suitable for wet environments, the device is designed to resist corrosion and wear. Its integration into a system depends on correct positioning relative to flow direction and system dynamics. Factors affecting long-term performance include exposure to extreme temperatures, mechanical shock, and regular overpressure events beyond the rated range.

Service and operation

Routine checks should include verifying the pointer returns to zero when the system is depressurised and ensuring the glass face remains intact. Any visible cracks or distortion suggest the need for replacement. No scheduled service intervals are provided in the technical data. If the gauge fails to provide consistent readings, it should be removed and tested against a certified reference device.

Frequently asked questions

Can this pressure gauge be used in steam systems?
It is not designed for use with steam. The technical specifications indicate suitability only for liquid media such as water.

Is the rear connection threaded or soldered?
The rear connection is threaded with a 1/4 inch male thread for secure and leak-free installation.

What is the maximum operating pressure before damage occurs?
While the gauge is rated for 0–10 bar, exceeding this range may cause permanent deformation of the internal sensing element.

Does the dial size affect readability in low light?
The 50 mm dial provides sufficient contrast and scale markings for visibility under normal lighting conditions.
