Thermometer - axial, D 63/L 100 mm

Product detailed description

Axial thermometers are essential components in heating and plumbing systems where accurate temperature measurement is required. They are commonly used in residential and commercial buildings for monitoring system performance in boilers, heat exchangers, and circulation loops. Installers and service technicians often integrate these devices into systems to ensure safe and efficient operation. The IVAR TP 120 A is suitable for applications involving water or glycol-based media within the specified temperature range.

The TP 120 A is typically installed in locations with limited space due to its compact axial design. It is frequently found in closed-loop systems where temperature stability is critical. The rear-threaded connection allows for secure mounting in pipe walls, ensuring long-term reliability and minimal maintenance. This model is particularly suited for systems requiring frequent access or adjustments.

The temperature range of 0 to 120°C makes this thermometer suitable for most heating and hot water systems. The 63 mm diameter ensures sufficient surface area for accurate readings, while the 100 mm probe length allows for insertion into standard pipe sizes. These dimensions are important for proper immersion depth and response time in the measured medium.

Installation and connection

The TP 120 A is installed using a rear-mounted 1/2 inch male thread. Ensure the pipe wall is clean and free of debris before threading the device. Use an appropriate sealing compound or gasket to prevent leaks. Verify that the insertion depth is sufficient to avoid false readings caused by insufficient immersion. Common mistakes include using the wrong thread type or failing to align the thermometer correctly with the pipe axis. Always confirm the media compatibility and ensure the system is depressurised before installation.

Compatibility and accessories

This thermometer is compatible with standard temperature control systems and monitoring devices. For complete functionality, it should be paired with a compatible display or controller unit. No additional accessories are required for basic operation. Ensure the selected controller supports the temperature range and signal type of the thermometer.

Technical background for designers

The TP 120 A operates on a bimetallic or resistance principle, depending on the internal sensor type. The housing is typically made of corrosion-resistant materials suitable for wet environments. The rear-threaded design allows for integration into existing pipe walls without the need for extensive modifications. The accuracy and response time depend on the immersion depth and the thermal conductivity of the medium. To maximise efficiency, avoid placing the thermometer near valves or elbows where turbulence can affect readings.

Service and operation

Routine checks should include visual inspection for signs of corrosion or mechanical damage. Verify the tightness of the thread connection and the integrity of the sealing. No regular calibration is specified for this model. If the thermometer fails to provide consistent readings, disassemble and inspect for blockages or wear. Replace if necessary to maintain system performance.

Frequently asked questions

Can the TP 120 A be used in a closed-loop heating system?
Yes, the TP 120 A is suitable for use in closed-loop systems operating within the specified temperature range. Ensure the media is compatible with the thermometer’s materials.

What is the minimum pipe size for installation?
There is no specific minimum pipe size provided, but the 1/2 inch rear thread requires sufficient space for secure installation. Avoid using in pipes with internal obstructions.

Is the TP 120 A suitable for outdoor installation?
No specific information is available regarding outdoor use. Install in protected areas to prevent exposure to extreme weather conditions or direct moisture.

Can the TP 120 A be replaced without draining the system?
Replacement is possible if the system is depressurised and drained to prevent spillage. Always follow safety procedures when working with pressurised or hot systems.
