Online fork density (concentration) sensor is a continuous on-line instrument for measuring liquid density, mainly used in industrial process automation control. It generates a corresponding 4-20mA analog signal based on the density change of the medium, and can also output a digital signal for remote calibration and monitoring after conversion. Depending on the different industrial processes, density can be expressed as: Brix, GL, Baume, Plato, and percentage concentration.

The tuning fork density meter utilizes industrial-grade high-performance single-chip integrated circuits, with a microprocessor handling complete signal adjustment, calculation, and diagnostic functions, eliminating the need for remote electronic devices for processing. It boasts high accuracy, excellent stability, and strong anti-interference capability. Input and output signals are completely isolated, facilitating users in designing anti-interference systems. Power supply features isolated circuit design, wide-range precision power, shock resistance, and anti-interference. Sensor signals are designed with photoelectric isolation.

Typical application industries include petrochemicals, brewing, food industry, and mineral processing (such as clay, carbonates, silicates, etc.), specifically used for interface detection in multi-product pipelines in these industries, density detection, reactor endpoint monitoring, and clarifier interface detection.
