SL80 Magnetostrictive Level Transmitter

The SL80 magnetostrictive level transmitter is a high-precision product widely used for process-level measurement. Its transducer sends a pulse along a waveguide wire, generating a circular magnetic field on the surface. This field interacts with the magnetic field of the float ball's permanent magnet, which changes the lattice spacing in the waveguide, generating a torsional pulse. By measuring the time difference between the sent and received pulses, the exact liquid level can be determined and converted into an electrical signal for remote control. This product’s accuracy is unaffected by dielectric constant, temperature, or pressure variations, ensuring high precision and low maintenance.
