The Shridhan MLX Series comprises Magnetostrictive Level Transmitters for high-precision continuous liquid level measurement.
The magnetostrictive sensing principle determines float position along the probe and provides continuous level measurement with 4-20mA or 4-20mA with HART output.
Available in rigid, flexible, plastic-coated rigid and mini probe versions, with probe lengths from 0.5 m up to 15 m depending on configuration.

The Shridhan MLX Series Magnetostrictive Level Transmitter is a continuous level measurement instrument designed for accurate gauging of liquid levels in tanks and vessels.
The MLX uses the physical principle of magnetostriction. A rigid magnetostrictive wire is installed inside the probe tube while a magnetic float moves along the probe with the liquid level.
The transmitter electronics send a current pulse through the magnetostrictive wire. Interaction between the resulting magnetic field and the magnetic field of the float produces a torsion wave. The time taken for this wave to reach the probe head is measured and used to determine the position of the float.
The MLX is available in different probe constructions and output configurations, including high-resolution 4-20mA and HART versions, as well as explosion-proof and intrinsically safe configurations.
These features are listed in the MLX special-features section of the manufacturer brochure. :contentReference[oaicite:1]{index=1}
Inside the probe tube is a rigid wire made from magnetostrictive material. The sensor electronics send a current pulse through the wire, creating a circular magnetic field.
A magnet is integrated into the float. As the float moves with the liquid level, its magnetic field interacts with the magnetic field generated around the wire.
This interaction generates a torsion wave in the wire. The electronics measure the transit time of the wave and use it to calculate the exact position of the float.
| Component | Function |
|---|---|
| Magnetostrictive Wire | Carries the current pulse and generates the magnetic field used for position sensing. |
| Magnetic Float | Moves with the liquid level and provides the magnetic field required for measurement. |
| Torsion Wave | Travels along the magnetostrictive wire following the interaction of the magnetic fields. |
| Transmitter Electronics | Measures wave transit time and converts float position into the selected output. |
The operating principle is illustrated and explained on page 8 of the brochure. :contentReference[oaicite:2]{index=2}
