Thermometer - axial, D 100/L 75 mm

Product detailed description

Axial thermometers are commonly used in residential and commercial buildings for monitoring the temperature of fluids in closed-loop systems such as heating circuits, hot water storage tanks, and industrial process lines. Installers often integrate these devices into systems where accurate and stable temperature measurements are critical for system performance and safety. The IVAR TP 120 A is suitable for applications involving liquid media and where the thermometer is mounted directly into the flow path. The compact design allows for installation in tight spaces, while the robust construction ensures reliable readings over time.

The thermometer is typically used in conjunction with control systems, alarms, or monitoring equipment to ensure that the temperature remains within safe and efficient limits. It is commonly found in boiler rooms, underfloor heating systems, and in heat exchangers. The probe is inserted into the fluid stream to measure the actual temperature, making it ideal for dynamic environments where rapid response is required.

The diameter of 100 mm and well length of 75 mm determine the immersion depth and surface area in contact with the medium. These dimensions are essential for ensuring sufficient thermal contact and avoiding measurement errors due to insufficient immersion. The temperature range of 0 to 120°C covers typical conditions in heating and hot water systems, making this thermometer suitable for a wide range of applications.

Installation and connection

The thermometer is installed by screwing it into a threaded opening in the pipe or vessel using the rear connection. The external thread is 1/2 inch M, which must be matched with the corresponding female thread in the installation point. Before installation, the installer should verify the correct orientation of the probe to ensure it is fully immersed in the fluid. The probe should be positioned so that it is not obstructed by pipe fittings or insulation. Common installation errors include incorrect thread matching, insufficient immersion depth, and improper sealing, which can lead to leaks or inaccurate readings.

Compatibility and accessories

This thermometer is compatible with standard control and monitoring systems that accept standard temperature sensors. For complete system integration, it may need to be connected to a transmitter or controller. No specific accessories are required for basic operation, but sealing compounds or gaskets may be needed for a watertight seal during installation. There are no alternative or related products listed for this model.

Technical background for designers

The operating principle is based on thermal expansion or resistance change in a sensing element, depending on the internal design. The probe is constructed from materials that resist corrosion and thermal stress, ensuring long-term stability in liquid environments. The rear connection allows for secure mounting in pipes or vessels. The service life and accuracy depend on the quality of the installation, the purity of the medium, and the absence of mechanical stress on the probe. Proper integration into the system ensures that the thermometer responds quickly and accurately to temperature changes.

Service and operation

Regular inspection is recommended to ensure the probe is free from deposits or damage. The installer should check for signs of leakage around the connection and verify that the probe is fully immersed. No specific service intervals are provided in the brief. If the thermometer is suspected of providing incorrect readings, it should be removed and tested against a reference device. Avoid exposing the probe to temperatures outside the specified range, as this may cause permanent damage.

Frequently asked questions

Can the thermometer be used in hot water storage tanks?
Yes, the thermometer is suitable for hot water storage tanks as long as the temperature does not exceed 120°C and the medium is compatible with the probe material.

Is the probe suitable for vertical installation?
Yes, the probe can be installed vertically, but it must be fully immersed in the fluid to ensure accurate readings.

What type of thread is used for the connection?
The external thread is 1/2 inch M, which should be matched with a corresponding female thread in the installation point.

Can the thermometer be used with digital control systems?
Yes, the thermometer can be integrated with digital control systems that accept standard temperature input signals.
