Pressure gauge - radial, D 50, 0 - 16 bar

Product detailed description

Radial pressure gauges are commonly used in residential and commercial heating, plumbing, and sanitation systems to monitor pressure levels. Installers and service technicians rely on these devices to ensure system integrity and performance. In hydronic heating systems, for example, pressure gauges help detect leaks, monitor pump performance, and verify correct system charging. The compact 50 mm diameter design allows for installation in tight spaces, such as boiler rooms, under floor panels, or in mechanical rooms. The gauge is suitable for use with water-based systems and is often mounted near expansion vessels, circulators, or safety valves to provide real-time pressure feedback.

Proper installation and selection of pressure gauges are essential to avoid misreadings and system damage. The 0–16 bar range is suitable for low-pressure systems, including domestic hot water circuits, underfloor heating, and small-scale heating systems. The gauge must be installed in a location free from vibration and direct exposure to heat sources to ensure accurate readings and long-term reliability.

The 50 mm diameter is a standard size for compact installations. The 0–16 bar range is appropriate for low-pressure applications such as domestic heating and water circulation systems. The 1/4 inch male thread is a common connection for small-diameter piping and fittings. The gauge is not available in larger sizes such as 80 mm unless ordered specifically.Installation and connection To install the pressure gauge, first ensure the system is depressurised. Use a 1/4 inch pipe thread to connect the gauge to the system. Apply thread sealant or PTFE tape to the male thread to prevent leaks. The gauge should be mounted vertically with the dial facing outward for easy reading. Avoid installing the gauge in locations with high vibration or temperature fluctuations, as these can affect accuracy. A common mistake is failing to align the gauge correctly, which can lead to incorrect readings or damage to the internal mechanism.Compatibility and accessories This pressure gauge is compatible with standard 1/4 inch threaded fittings and piping. It is often used in conjunction with expansion vessels, safety valves, and circulator pumps. For larger installations or higher pressure ranges, alternative models may be required. No additional accessories are included with the gauge, so thread sealant and mounting brackets may need to be purchased separately.Technical background for designers Radial pressure gauges operate using a Bourdon tube mechanism, where pressure causes the tube to deform and move a pointer across a dial. The gauge is constructed from durable materials suitable for water-based systems. The 1/4 inch connection allows for secure integration into piping systems. The service life and accuracy depend on the quality of the internal mechanism and the environmental conditions during operation. Exposure to excessive vibration or temperature extremes can reduce the gauge's lifespan and affect its performance.Service and operation Regular visual inspections should be carried out to check for leaks, corrosion, or damage to the gauge housing. The pointer should return to zero when the system is depressurised. If the gauge shows erratic readings or fails to reset, it may need recalibration or replacement. No specific service intervals are provided in the technical data, but it is recommended to replace the gauge if it shows signs of wear or inaccuracy.Frequently asked questions

Can this gauge be used in a closed-loop heating system?
Yes, the 0–16 bar range is suitable for closed-loop systems such as underfloor heating and domestic hot water circuits.

Is the gauge suitable for use with glycol-based fluids?
There is no specific information on compatibility with glycol, so it is recommended to consult the manufacturer's technical data sheet for confirmation.

Can the gauge be mounted horizontally?
No, the gauge should be mounted vertically with the dial facing outward to ensure accurate readings and proper operation.

Can the gauge be used in high-vibration environments?
No, the gauge should be installed in a location free from excessive vibration to prevent damage to the internal mechanism and inaccurate readings.
