The magnetostrictive level transmitter is a new type of liquid level measuring instrument used for continuous measurement of liquid level and interface. Measuring range: 0.2m～23m; accuracy optional: ±1mm, ±5mm, ±1cm, ±2cm, ±5mm.
Our Sino-Inst magnetostrictive level transmitter can provide two independent outputs: one, interface; two, overall level. It can be applied when the specific gravity difference is reduced to 0.02. Commonly used for measuring oil-water interfaces, and others including acid tanks, propane containers, desalters and sewage tanks.
Structure of Magnetostrictive Level Transmitter
Magnetostrictive Level Transmitters are divided into three series: flexible probe rod type, hard probe rod type, and external float isolation detection series. The meter body contains two main parts: the electronic part and the sensing part.
Sensing part (probe):
The probe rod is 5/8” in diameter and has a sealed end. The interior of the probe rod is hollow and contains precision magnetostrictive wire.
In addition to the magnetostrictive wire, the probe rod can also be equipped with up to 8 RTD temperature sensors for temperature detection.
The maximum length of the probe rod can be 23 meters, and all probes above 6 meters adopt a flexible cable structure.
Electronic part (i.e. transmitter):
The shell is made of aluminum alloy or 304 stainless steel, and is double-chamber type (that is, the transmission part and the wiring part are separated). One cavity contains the microprocessing module and circuit board. The microprocessing module has operating buttons, and the other cavity contains the binding posts.
There is a wire connecting the circuit board to the probe processing board.

Magnetostrictive Level Transmitter working principle
The magnetostrictive liquid level/interface level transmitter is designed using the principle of magnetostriction, a physical phenomenon.
The specific working principle is as follows:
A fine magnetostrictive wire is installed in a non-magnetic sensing tube. One end of the magnetostrictive wire is connected to a piezomagnetic sensor. The piezomagnetic sensor sends 10 current pulse signals to the magnetostrictive wire every second. And timing. The current pulse is transmitted downward along the magnetostrictive line, generating a downward-moving ring magnetic field.
The annular magnetic field interacts with the magnetic field of the magnetic float, generating a torsional stress wave on the magnetostrictive line. This torsional stress wave travels from the position of the float to the upper and lower ends along the magnetostrictive line at a known speed. It is known that Until the piezomagnetic sensor receives this torsional stress wave signal.
The time interval between the initial current pulse wave and the return torsional stress wave can be known through the timing circuit. The position of the float can be determined based on the time interval. Since the float always floats on the liquid surface, the liquid level can be accurately determined s position.
