Magnetostrictive Probe

Windbell SP series magnetostrictive probe take advantage of Wiedemann effect, Villari effect and Ultrasonic effect of intelligent material, by measuring time value difference which can be easily measured with high-precision, to convert to displacement difference, can accurately measure the product level, water level, and temperature for individual tanks.


  • Real time data transmission.
