MLT magnetostrictive level transmitter is designed and developed according to the magnetostrictive principle. It is a mordern highly accurate level measuring instrument with the advantages of highly accuracy, fast responding, good reliability, long life, and smart structure, etc.
MLT Magnetostrictive level transmitter can transform the medium level inside the container into two-wire system 4-20mA standard signal, simultaneusly with HART communicating. The product is widely used in petroleum, chemical, metallurgy, food fields and so on.
Magnetostrictive sensor is the core of magnetostrictive level transmitter. The core element of the sensor ( magnetostrictive line) is rare earth giant magnetostrictive material which enjoys the reputation of " black gold" in the modern industrial world. With the advantages of high strain, high electric (magnetic) mechanical wave conversion ability, etc., it can convert the small change of magnetic vector into a mechanical wave.
