RS Serial Magnetostrictive Level Sensor
Magnetostrictive Level Sensor(liquid level) sensor is a high-precision, large-range absolute position sensor developed by magnetostrictive effect. It has non-contact measurement, high reliability and long service life feature. And can withstand the harsh industrial environment such as oil stains, solutions, dust, high pressure, so it has been widely used in petrochemical, machinery, water, electricity, metallurgy, steel and other industries.
The sensor generates a pulsed magnetic field by a pulse current emitted along a waveguide, and when the magnetic field intersects with a magnetic field generated by a moving magnet near the waveguide wire, a strain pulse is generated due to the magnetostrictive effect, or the waveguide is twisted. The strain pulse is returned along the waveguide wire and received by the circuit. The time difference between the transmitted pulse and the echo signal is calculated by the circuit to accurately feedback the position of the movable magnet. This process is continuous, so every time the moving magnet is moved, the new position is quickly sensed.

Applications
Magnetostrictive level sensors are utilized across multiple industries due to their high accuracy, reliability, and ability to operate in harsh environments. Here are some key applications:
Liquid Level Measurement in Storage Tanks
Petroleum and Chemical Industries: These sensors are extensively used for measuring liquid levels in storage tanks for chemicals, fuels, and oils. Their high precision (better than 0.01% FS) makes them ideal for critical applications where accurate monitoring is essential.
Underground Storage Tanks: In gas stations and other facilities with underground tanks, magnetostrictive sensors provide real-time monitoring of fuel levels without the need for manual checks, enhancing safety and efficiency.
Environmental Monitoring
Water and Wastewater Treatment: Magnetostrictive sensors are employed to monitor water levels in treatment facilities. They help control pump operations, detect leaks, and manage chemical dosing accurately due to their ability to measure multiple parameters simultaneously.
Reservoir and Dam Monitoring: These sensors can also be used to monitor water levels in reservoirs and dams, providing crucial data for flood management and resource allocation.
Industrial Process Control
Biochemical and Pharmaceutical Industries: In these sectors, magnetostrictive sensors facilitate the monitoring of liquid levels in reactors and storage tanks, ensuring optimal process control and compliance with safety regulations.
Food and Beverage Industry: They are used for monitoring liquid levels in production processes, ensuring that operations run smoothly without interruptions due to low or high liquid levels.
