Magnetostrictive Level Transmitter ZM-L Series

Introduction – Magnetostrictive Level Transmitter ZM-L Series

The Magnetostrictive Level Transmitter ZM-L Series is a high-precision and long-lasting solution for continuous liquid level measurement. Operating on the magnetostrictive principle, this transmitter detects the position of a magnetic float to determine the liquid level with exceptional accuracy. It is commonly installed on the exterior of bypass level indicators, ensuring stable, reliable performance in a wide range of industrial applications.

The measuring process starts with a current impulse that generates a circular magnetic field along a tensioned magnetostrictive wire inside the sensor tube. When the float’s magnetic field interacts with this impulse, a torsional mechanical wave is created and converted into an electrical signal by a piezoceramic pickup. By measuring the time delay of this signal, the system determines the exact position of the float — and hence, the liquid level — with millimeter-level precision.

Engineered for high resolution, durability, and resistance to magnetic interference, the ZM-L Series ensures consistent accuracy even in harsh environments. With multiple signal outputs such as 4–20 mA, 0–10 V, and digital interfaces like CANopen, CANbus, and EtherCAT, it is fully compatible with modern control systems.

Widely adopted across industrial automation, oil and gas, water treatment, and process industries, this transmitter is trusted for its maintenance-free operation and long service life. Distributed by Dubai Sensor, it serves as a dependable choice for accurate level control in the UAE and MENA industrial sectors.
