Bimetallic thermometer A43 For heating technology, 0 °C - 120 °C, sensor: 60 mm, dia 100mm 14207763

WIKA A43 Bimetallic Thermometer for Professional Heating Systems

The WIKA A43 bimetallic thermometer is a proven solution specifically designed for heating technologies and district heating systems. This model represents the standard version intended for simple and reliable temperature indication in industrial applications and heating installations.

Durable Construction and Materials

The device features a robust construction with a galvanized steel housing, ensuring corrosion resistance and long-term operation under demanding industrial conditions. The case has a diameter of 100 mm, providing excellent scale readability even from a distance.

The 60 mm long sensor, made of aluminum, ensures fast and precise temperature measurement. The measuring element is a bimetallic spiral that converts temperature changes into pointer movement with high repeatability.

The thermowell, made of brass, is detachable and screw-mounted, facilitating easy installation and maintenance of the device. The acrylic (SAN) glass protects the mechanism against mechanical damage while ensuring good reading clarity.

Operating Parameters and Measurement Accuracy

The thermometer offers a measurement range from 0°C to 120°C, covering typical temperature monitoring needs in heating systems and domestic hot water (DHW) installations. Accuracy class 2.0 according to DIN EN 13190 guarantees precise measurements essential for proper control of heating processes.

The G1/2B process connection enables standard threaded mounting in most industrial installations. The thermowell can operate at a maximum working pressure of up to 6 bar, allowing safe use even under pressure.

The modular design of model A43 allows various combinations of housing materials, nominal sizes, and sensor lengths, while maintaining essential dimensions and operating parameters.

Application in Modern Heating Systems

The thermometer is widely used in professional heating installations, particularly as a component for monitoring the temperature of the heating medium. In district heating applications, precise control of operating parameters is crucial for energy efficiency.

In solar installations, it enables control of the working medium temperature in solar collectors. In heat exchange stations, the thermometer serves as a key control element, allowing operators to continuously monitor operating parameters and quickly respond to any deviations from standard temperature ranges.
