A magnetostrictive sensor generates a magnetic field in the circumferential direction of a magnetostrictive line when a current pulse is applied to a magnetostrictive line stretched in a stem.
Due to the difference of the vector with the magnetic field emitted from the magnet in the float, distortion occurs in the magnetostriction line at that part and
can be observed as a magnetostriction signal. By measuring the reflection time of the magnetostrictive signal, the position of the float can be measured reliably and the liquid level can be observed linearly.
It is possible to monitor the change of very small liquid level,less than 0.1 mm, so it is suitable for monitoring the leak of a tank. In addition, even if there is steam, bubbles,
condensation in the tank, the level can be reliably detected. The HL-G5 type, which miniaturizes the HL-G to the limit, is also available.
