Operating Principle
The magnetostrictive level transmitter utilizes the principle of magnetostrictive wire (waveguide wire) to measure the liquid level. The probe contains a magnetostrictive wire made of non-magnetic stainless steel tube, effectively protecting the waveguide wire. During operation, the pulse generator in the electronics compartment emits an initial pulse, which generates a rotating magnetic field as it travels through the waveguide wire. When this magnetic field encounters the permanent magnetic field in the float, it induces a magnetostrictive effect, causing the waveguide wire to twist and generate a constant-speed mechanical wave. This mechanical wave propagates in two directions, with part of it absorbed by the damper and the other part sensed by the pickup mechanism and converted into electrical pulses. The pickup mechanism then calculates the time difference between pulses, accurately measuring the height of the liquid level being measured.
Product Advantages
1. Wide Applicability: The magnetostrictive level transmitter offers various probe forms, process connection types, and material options for customization, catering to diverse requirements and ensuring broader applicability.
2. High Reliability: Utilizing waveguide principles, the transmitter has no moving mechanical parts, friction, or wear. Enclosed within a stainless steel tube, it operates without direct contact with the measured medium, ensuring strong reliability and long lifespan.
3. High Precision: With high measurement accuracy and resolution better than 0.01%FS, it enables precise liquid level measurement, surpassing other sensors in accuracy.
4. Excellent Safety Performance: Designed with intrinsic safety and explosion-proof features, it is particularly suitable for measuring chemical raw materials and flammable liquids, eliminating the need to open tank covers and enhancing safety during measurements.
5. Easy Installation and Maintenance: Typically installed through existing pipe openings, it is suitable for underground and operational tanks, ensuring minimal disruption to normal operations during installation and maintenance, thus improving convenience and efficiency.
