◆SP Magnetostrictive probe

   

SP300 Magnetostrictive probe
Windbell SP series magnetostrictive probe is the core part of Automatic tank gauges products. This probe take advantages of Wiedeman effect, Viuary 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, so achieven high accuracy measuring for liquid product level.

 Applied liquid products

Gsaoline, Diesel, Kerosene, Ethanol Gasoline, Bio Diesel,  Water

Data measured

Product level, Water level, Temperature, Product inventory, Empty capacity (Order capacity)

Features

• Transfer probe data to console in real time, including product level, water level, tempature

• 5 points temperature sensors offer precision measurement as the basis of temperature compensation and leak detection

• Digital signal transmit have remarkable highlights than traditional analog signals, especially on high anti-interruption ability, enhance long distance communication as 500m, and higher security.

• Leak detection ability support 0.38Liter/Hour, and 0.76Liter/Hour, static and dynamic leak detection connects with SS160 console. This programmable Leak Detection can be set detect by daily, weekly, monthly or annually.
