magnetostrictive thermometer is using magnetostrictive principle the development and production of high precision displacement measurement sensor, with high measurement precision, stable and reliable, long life, structure compact, the advantages of strong adaptability to environment, in addition, the top of the tank is installed without the tank, has the characteristics of safe, convenient and fast.

magnetostrictive technology principle is to use two different magnetic fields intersect to create a strain pulse signal, and then calculate the signal by detecting the amount of time required to cycle, so as to figure out the exact location. Was designed based on magnetostrictive principle. Electronic thermometer warehouse within the electronic components to create a low pressure pulse current, at the same time produce a magnetic field propagation along the transmission line is down, move up and down float along the rod with liquid level change, because the float contains a set of magnets, also produce a magnetic field, when two magnetic field when they met, namely to produce a called & other; Waveguide twisted & throughout; Pulse, also called & other; Return & throughout; Pulse. One from the two magnetic field activities of the magnet to the outside of the sensor, the other is from the sensor waveguide ( 波导) Current pulses, and the current pulse is produced by the inherent electronic parts of the sensor head.

when two intersecting magnetic field, produced by a strain pulse will run to the fixed speed of sound (back to the electronic components of the sensor coil. From moment to generate an electric current pulse response variable pulse measuring the time required to cycle times the fixed speed, we can accurately calculate the changes in the position of the magnet. This process is continuous, so whenever activity magnet is driven, the new location will soon be measured. Because the output signal is a true absolute position output, rather than the proportion of processing or need to amplify the signal, so there is no signal drift or value, so don't have to be like other displacement sensor need heavy label and maintenance on a regular basis.
