Devices called magnetostrictive level transmitters use magnetic force to measure the level of a liquid or solid in a container. A magnetostriction sensor, which is a wire coil wrapped around a magnetostrictive substance, makes up the transmitter.
The sensor is coupled with an electronics module, which measures the magnetic field it produces and transforms it into a signal that can be interpreted by a controller or display device.
A magnetic field causes the magnetostrictive material’s length to vary, and this change in length is what the magnetostrictive sensor measures. Depending on how strong the magnetic field is, a material will either expand or contract when subjected to it.
Three major parts make up magnetostrictive float level measurement sensors. In the fluid being monitored, a hollow stem with a waveguide constructed of ferromagnetic material is hung. Along with the liquid’s surface, a hollow float glides up and down the stem.
A permanent magnet is housed inside this float. The magnetic molecules of the waveguide in the stem’s magnetic field are repositioned as the float moves due to its magnetic field.
The electronics of the device make up the third element. At regular intervals, the electronics generate an electromagnetic pulse.This pulse generates its own magnetic field as it moves through the waveguide.
Conflicting magnetic fields cause vibrations in the waveguide when this pulse hits the float, which then causes a torsional stress wave, or strain pulse, to propagate back up the waveguide at a given speed.
The Global Magnetostrictive Level Transmitter market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The magnetostrictive level transmitter, which has a two-float design, precisely measures the level of a wide range of liquids, including interface and insoluble multiple liquids, using buoyancy, magnetostriction, and electronics technologies.
A float that is designed correctly for the fluid density is installed on the level transmitter stem in a standard magnetostrictive level transmitter so that it can move up and down due to buoyancy from the fluid being measured. A magnetic component can be found in the float.
The magnetostrictive level transmitter electronics creates a magnetic field along the whole length of a sensor wire that is situated inside the level transmitter stem in order to find the float position. The magnet-generated field inside the float and this field start interacting right away.
Continuous float level sensors known as magnetostrictive level transmitters produce competing magnetic fields to produce a signal related to the level of a liquid in order to measure the level in close to real time.
Radar transmitters, ultrasonic sensors, and submersible pressure transducers are some other varieties of continuous level sensors. These all have distinctive qualities that either make them good or unfit for certain uses.
Only ferromagnetic materials, or those that are drawn to or capable of creating permanent magnets, exhibit the magnetostriction feature.
It describes how these elements or compounds respond to the application of a magnetic field by expanding or contracting as a result of the ferromagnetic molecules present in those elements or compounds. In essence, they are able to transform electromagnetic energy into mechanical or vibrational energy.
