Analogue Level Measurement Reed Chain

Analogue Level Measurement Using Reed Chain: A Reliable Solution for Precise Liquid Monitoring

In today’s industrial landscape, accurate liquid level measurement plays a vital role in ensuring efficiency, safety, and process optimization. From chemical plants to cooling systems, maintaining precise liquid levels is essential for smooth operations. Analogue level measurement using a reed chain has established itself as a highly reliable and effective solution for continuous level monitoring.

The reed chain level sensor operates using a combination of a float and a reed switch chain. The float, which contains a magnet, moves up and down as the liquid level changes. The reed chain consists of multiple magnetic reed switches positioned at fixed intervals along a metal strip inside the tank or container.

When the float moves with the liquid, the magnet inside the float interacts with the reed switches, causing them to close and generate electrical signals. These signals are then processed by a control unit, converting them into a precise, real-time measurement of the liquid level. The sensor can provide analogue outputs such as 4-20mA or 0-10V, making it compatible with industrial monitoring and automation systems.

Advantages of Reed Chain Level Sensors

• High Reliability: Reed chain sensors provide consistent and precise level detection due to their simple yet effective magnetic switching mechanism.
• Robust Construction: These sensors are resistant to vibrations, shocks, temperature fluctuations, and humidity, making them ideal for harsh industrial environments.
• Easy Installation: They can be seamlessly integrated into tanks and containers of various sizes without complex setup requirements.
• Cost-Effective: Compared to other level measurement technologies, reed chain sensors offer a low-cost, maintenance-friendly solution with a great price-to-performance ratio.
