Radial Pressure Gauge, 0 - 6 Bar, 100 mm

Product detailed description

This radial pressure gauge is commonly used in heating systems, industrial installations, and mechanical environments requiring accurate pressure monitoring. Installers typically fit these devices in boiler rooms, pump stations, and mechanical workshops where continuous pressure readings are essential for safety and performance. The device is suited for permanent mounting on pipework or equipment and is frequently used alongside safety valves and control systems to ensure stable pressure levels.

The 100 mm dial size allows for easy reading at a distance, while the steel construction ensures durability in high-traffic or high-vibration settings. Its accuracy class 1.6 provides reliable measurements suitable for both diagnostic checks and ongoing monitoring. The rear 1/2 inch threaded connection facilitates secure and leak-free installation when connected to copper, steel, or plastic piping.

The pressure range of 0–6 bar defines the operational window for this gauge, making it suitable for low- to medium-pressure applications such as domestic central heating or light industrial systems. The dial size of 100 mm allows for precise visual interpretation even in low-light conditions. The accuracy class 1.6 ensures that deviations remain within acceptable limits for routine diagnostics and system monitoring. The 1/2 inch rear connection is a standard size used in most European heating and plumbing systems, ensuring compatibility with existing fittings and pipe diameters.

Installation and Connection

To install the gauge, first verify that the system is depressurised and that all relevant valves are closed. Use a suitable wrench to fit the gauge onto the 1/2 inch threaded port, applying a sealing tape or gasket if required. Ensure the gauge is mounted vertically and that the dial is visible for regular inspection. Check that the connection is tight but avoid over-tightening to prevent damage to the threads or internal mechanisms. Common installation errors include incorrect orientation, which can affect readability, and using incompatible sealing materials that may degrade under heat or moisture.

Compatibility and Accessories

This radial pressure gauge is designed to work with standard 1/2 inch threaded ports found in central heating boilers, expansion vessels, and circulation pumps. For complete system monitoring, consider pairing it with pressure-reducing valves or safety relief valves. Additional accessories such as mounting brackets or protective covers may be necessary in high-moisture or outdoor environments. Related products include pressure switches and digital readout modules for advanced systems.

Technical Background for Designers

The operating principle of this gauge relies on a Bourdon tube mechanism, which deflects in response to fluid pressure. The steel body provides structural integrity and resistance to corrosion, while the glass cover protects the dial from physical damage. The rear-threaded design allows for compact installation behind panels or in confined spaces. The integration into the system depends on the location of the port and the orientation of the gauge. Environmental factors such as vibration, temperature fluctuations, and exposure to aggressive fluids can affect the service life and accuracy of the gauge over time.

Service and Operation

During operation, regularly inspect the gauge for signs of leakage around the connection and for any visible cracks in the glass cover. Verify the accuracy periodically using a calibrated reference gauge, especially after system maintenance or in high-use environments. There are no specified service intervals in the provided data, but annual checks are recommended in critical installations. Replace the gauge if the pointer sticks, the glass is cracked, or the readings consistently fall outside expected ranges.

Frequently Asked Questions

Can this gauge be used in steam systems?
It is not specified whether this model is suitable for steam applications. Refer to the manufacturer’s technical documentation for confirmation.

Is the glass cover replaceable?
No further details are available on the replaceability of the glass cover. Contact the manufacturer for replacement parts or guidance.

Can this model be mounted horizontally?
While vertical mounting is ideal for optimal readability, horizontal mounting may be possible depending on space constraints. Ensure the dial remains clearly visible.

What media can this gauge measure?
The gauge is designed for general liquid and gas pressure measurement, but specific compatibility with certain media is not stated in the provided data.
