Axial thermomanometer 0°C - 120°C 0 - 6 bar, 63 mm

Product detailed description

In residential and commercial heating systems, accurate monitoring of both temperature and pressure is essential for efficient operation and early detection of anomalies. Installers frequently encounter situations where two separate instruments would otherwise be required. This axial thermomanometer integrates both functions into one compact device, reducing installation time and space requirements. It is commonly used in boilers, heat pumps, and central heating systems where simultaneous monitoring of these parameters is necessary.

The 63 mm dial size ensures easy readability in tight spaces, such as behind panels or within boiler enclosures. The axial design allows for installation in areas with limited access, making it ideal for retrofitting or new installations in modern heating systems. The ABS housing and acrylic cover provide durability and resistance to corrosion, ensuring long-term reliability in humid environments typical of heating system compartments.

The temperature range of 0 to 120°C covers typical operating conditions for heating circuits, including both domestic hot water and central heating. The pressure range of 0 to 6 bar is suitable for low-pressure systems such as closed-loop heating circuits. The accuracy class of 2.5 indicates acceptable precision for monitoring purposes but not for calibration or high-precision control applications. The 63 mm dial is sized for visibility while fitting standard mounting spaces.

Installation and connection

To install the thermomanometer, first locate a suitable position near the heat source or circulation point in the system. The axial port requires rear access for connecting the 1/2 inch inlet and 1/4 inch axial port. Ensure the mounting surface is clean and free from debris. Secure the unit using appropriate fasteners provided by the manufacturer. When connecting the 1/2 inch inlet, use a compatible pipe or fitting that allows unobstructed flow for the bimetal spiral sensor. For the 1/4 inch axial port, align the Bourdon tube connection carefully to avoid misalignment that could affect pressure readings. Tighten all fittings to the recommended torque to prevent leaks. A common mistake during installation is reversing the inlet and outlet ports, which can cause incorrect readings or damage to the sensor elements. Always verify the direction of flow and ensure the device is installed in a stable position to prevent vibration-induced wear.

Compatibility and accessories

This thermomanometer is compatible with standard heating systems that require dual monitoring of temperature and pressure. It is typically used in conjunction with circulation pumps, expansion vessels, and boiler control systems. Additional components such as pipe unions, sealing rings, and mounting brackets may be required depending on the specific installation. For systems requiring remote monitoring or digital integration, consider pairing this device with a compatible data logger or control panel. While no alternative products are listed, similar models from other manufacturers may offer additional features such as digital readouts or wireless connectivity.

Technical background for designers

The thermomanometer combines a bimetal spiral for temperature sensing and a Bourdon tube for pressure measurement. The bimetal spiral expands or contracts in response to changes in water temperature, moving the temperature pointer across the dial. The Bourdon tube, a curved metal tube that straightens under pressure, drives the pressure pointer. Both mechanisms operate independently but share the same aluminum dial, protected by an acrylic window. The ABS housing provides good chemical resistance and mechanical strength, making it suitable for installation in environments with moderate moisture levels. The axial design allows the device to be mounted flush with the wall or panel, minimizing protrusion into the working area. Integration into the system requires careful consideration of the sensor placement to ensure representative readings without interference from turbulence or air pockets. The service life of the device depends on the stability of the installation environment and the absence of excessive vibration or thermal cycling. Regular inspection of the seals and connections will help maintain accurate readings over time.

Service and operation

Routine maintenance includes checking the integrity of the seals and the condition of the dial cover for cracks or clouding that could impair readability. If the device shows signs of inaccurate readings, it should be compared against a reference instrument or recalibrated according to the manufacturer’s guidelines. The two-year warranty covers defects in materials and workmanship but does not include damage caused by improper installation or misuse. Installers should ensure that the device is not exposed to temperatures beyond its specified range or to non-compatible fluids. If the device is removed for replacement or repair, the system should be depressurized and drained to prevent injury or damage.

Frequently asked questions

Can the thermomanometer be mounted vertically or horizontally?
The device can be mounted in any orientation as long as the dial remains visible and the connections are accessible for installation and maintenance.

Is the device suitable for use with glycol-based heating fluids?
According to the manufacturer's technical data sheet, the device is intended for use with water. For glycol-based systems, consult the manufacturer for compatibility confirmation.

How is the accuracy of the device verified during installation?
The accuracy class of 2.5 means that the readings are expected to be within ±2.5% of the full scale. Verification should be carried out using a calibrated reference instrument.

Can the thermomanometer be used in a closed-loop solar heating system?
Yes, provided the system operates within the specified temperature and pressure ranges. The axial design is particularly useful in compact solar system enclosures.
