Overview:

UCZ type magnetostrictive liquid level transmitter is mainly designed and developed based on the principle of magnetostriction. It is a modern high-precision liquid level measuring instrument that combines the advantages of high measurement accuracy, fast response time, good reliability, long life, and exquisite structure.

UCZ type magnetostrictive liquid level transmitter changes the liquid level of the medium in the container into 4 ～ 20mA two-wire standard signal output, and has HART communication protocol, which can meet the requirements of various industrial sites. Products are widely used in petroleum, chemical, metallurgy, food, and other fields.

working principle:

The magnetostrictive sensor is the core of the magnetostrictive liquid level transmitter, and the core component of the sensor (magnetostrictive wire) is a rare earth super magnetostrictive material that enjoys the reputation of "black earth gold" in the modern industry. It has a high strain value. , Strong electrical (magnetic) mechanical wave conversion ability, and other advantages, can change small magnetic field vector changes into mechanical waves. The working principle is: there is a tensioned magnetostrictive wire (1) inside the sensing tube, and a current pulse (2) is emitted by the sensor circuit along the magnetostrictive wire, thereby forming a ring-shaped magnetic field around the magnetostrictive wire (3). Inside the liquid level float is a set of permanent magnetic steel (4), whose magnetic field makes the magnetostrictive line magnetize in the axial direction. When the two magnetic fields are superimposed, a torsional pulse (5) will be generated at the position of the float. This pulse is transmitted to the two ends along the magnetostrictive line, and one end is transmitted to the top of the sensing tube, which is accepted by the sensor circuit and the other end is transmitted to The bottom of the sensing tube. The time difference between the start pulse and the return pulse is measured to determine the float position.
