Product Description

 Product Description of Holykell SP series Magnetosrictive Probe:

Holykell SP series magnetostrictive probe take advantages of Wiedeman effect, Viuary effect and ultrasonic effect of intelligence material, convert displacement information to time value which most easily to be measured with high-precision, so achieve high accuracy measuring for liquid level. Because of few mechanical parts,magnetostrictive probe have distinct features as high reliability, easy-to-install and wide application, etc.


Magnetostrictive probe is mainly composed of electric house ,temperature sensors,protection steel pipe,magnetostrictive waveguide wire and floaters with magnet inside. Install electric house inside the riser pipe of oil tank, insert protection steel pipe into liquid in underground tank, floaters floats on the liquid surface, and slides up and down on pipe according to the changes of liquid level. Processing measured data of product level ,water level and average temperature of five-points by filtering algorithm, then transmit these data to smart console by digital communication port.


Control board of probe is composed of CPU ,instrument amplifier circuit and communication circuit. CPU adopts high-frequency processor, to ensure the instantaneity and reliability of data sampling. High-accuracy instrument amplifier circuit makes sure the authenticity of sampled data waveform. And digital communication make sure the reliability and anti-jamming when data transmit far away.
