detailed description



Chuanshuo magnetostrictive liquid level sensor is a modular assembled magnetostrictive liquid level sensor developed by our company, which provides high-speed, reliable, and accurate data processing and communication. Magnetostrictive liquid level sensors can provide multiple output modes, including analog voltage and current, digital RS485, etc. The output signal can provide one position, multiple positions, or one position plus one temperature output. The detailed multifunctional output mode provides customers with more choices. The HL magnetostrictive liquid level sensor produced by HL is non-contact and never wears out. Therefore, magnetostrictive displacement sensors have the advantages of high precision, high response, low hysteresis, high reliability, long lifespan, high stability, and easy installation. They do not require recalibration or regular maintenance, and are widely used in the field of precision measurement.


working principle:
The magnetostrictive liquid level sensor generates a starting pulse from the electronic circuit inside the electronic chamber. When this starting pulse is transmitted in the waveguide wire, a rotating magnetic field is generated along the direction of the waveguide wire. When this magnetic field meets the permanent magnetic field in the magnetic ring or floating ball, the magnetostrictive effect is generated, causing the waveguide wire to twist. This twist is sensed and converted into corresponding current pulses by the energy pickup mechanism installed in the electronic chamber. The time difference between the two pulses can be calculated by the electronic circuit to accurately measure the displacement and liquid level being measured. Calculate the accurate position of the magnetic field intersection point by detecting the time of strain pulse signals generated when two different magnetic fields intersect. A magnetic field is generated by a pulse excitation from the electronic components of the sensor electronic chamber. The excitation pulse generates a magnetic field that travels along a waveguide wire made of high magnetostrictive material inside the sensor measuring rod at the speed of light from the end of the electronic chamber to the tail end. When it intersects with an active permanent magnetic field (usually installed on a moving plate at the required detection position), due to the magnetostrictive phenomenon, the waveguide wire generates a mechanical strain pulse at the intersection point, and returns to the end of the electronic chamber through the waveguide wire at the speed of sound. The strain pulse is detected by the detection circuit in the electronic chamber. Therefore, the time between the emission of an aortic shock wave and the reception of a strain pulse wave is the time for the sound velocity to propagate in the waveguide (the time for the active wave to run has been ignored here, and the actual impact is only 0.0001%). Given the sound velocity (fixed at 3000m/s) and propagation time, this distance is naturally determined. When the permanent magnet moves to a new position, reconfirm the above measurement.
