Bimetallic thermometer A43 For heating technology, 0 °C - 120 °C, sensor: 40 mm, Ø 63mm 14199242

Professional Temperature Measurement for Heating Systems

The WIKA A43 bimetallic thermometer is a proven solution for precise temperature monitoring in district heating installations. With a diameter of 63 mm and a measuring range of 0°C - 120°C, this model is specifically designed for heating technology applications, offering an optimal combination of accuracy and reliability.

High-Quality Construction and Materials

The thermometer housing is made of galvanized steel, ensuring excellent corrosion resistance and long-term durability in demanding industrial environments. The sensor, with a length of 40 mm and a diameter of 9 mm, is constructed from aluminum, guaranteeing fast response to temperature changes and precise measurement.

The sensor sheath, made of brass, is detachable and screw-mounted, facilitating easy installation and maintenance. The process connection G1/2B enables standard integration into heating systems. The black plastic pointer and polystyrene (PS) glass ensure excellent readability under various lighting conditions.

Applications in Heating Systems

This thermometer is widely used in heating installations, hot water boilers, solar thermal systems, and heat exchange systems. Its robust construction makes it particularly suitable for environments requiring continuous temperature monitoring.

The operating principle is based on the thermal expansion of metals. Two metal strips with different coefficients of thermal expansion respond to temperature changes, transferring motion to a dial scale that allows for numerical reading.

Operating Parameters and Standard Compliance

The device operates across its full indication range without temperature limitations. The sensor is rear-centered, facilitating installation and ensuring measurement stability. The accuracy class is 2.0 according to DIN EN 13190, guaranteeing professional-grade measurement quality suitable for industrial applications.

The bimetallic thermometer features a simple and robust construction, providing high durability and the ability to operate under challenging thermal conditions. Despite its compact dimensions, it delivers reliable measurements essential for the proper execution of temperature-dependent technological processes.
