Magnetostrictive static level

1.Introduction to Magnetictive static level Product

Magnetostrictive static level is a high precision instrument designed to accurately measure displacement and settlement in a variety of projects.Static level system is a high-precision liquid level measurement system that is suitable for measuring relative settlement at multiple points.In use, the static level system is to install multiple static levelings on multiple monitoring points, and one monitoring point is selected as the reference point.Each static level is connected together to make the liquid level of the liquid inside each static level be on the same level.In this way, when a certain monitoring point settles, the liquid level height of the liquid inside each static level will change.Each static level measures the liquid level height of the respective internal liquid through its own internal measurement device.The liquid level height information of each static level is transmitted to the backend system.After calculation, the backend system can obtain the relative settlement of each monitoring point relative to the reference point.It is mainly used in vertical displacement monitoring of bridges, tunnels, bridges, subways, dams, foundation pits, large storage tanks, etc.

The magnetostrictive displacement (liquid level) sensor uses the magnetostrictive principle and generates a strain pulse signal by intersecting two different magnetic fields to accurately measure the position.The measuring element is a waveguide, and the sensitive elements inside the waveguide are made of a special magnetostrictive material.The measurement process is a current pulse generated in the electronic chamber of the sensor.The current pulse is transmitted in the waveguide, thereby generating a circumferential magnetic field outside the waveguide.When the magnetic field intersects with the magnetic field generated by the movable magnetic ring that is positionally changed on the waveguide, due to the magnetostriction, a strained mechanical wave pulse signal will be generated in the waveguide.This strained mechanical wave pulse signal is transmitted at a fixed sound speed and is quickly detected by the electronic chamber.Since the transmission time of this strained mechanical wave pulse signal in the waveguide is proportional to the distance between the active magnetic ring and the electronic chamber, this distance can be determined with high accuracy by measuring the time.Since the output signal is a true absolute value, not a proportional or amplified signal, there is no signal drift or change in value, and there is no need to re-regulate regularly.
