Magnetostrictive Level Meter Supports Continuous Sensing

Magnetostrictive Level Meter Supports Continuous Sensing
Kobold Instruments Inc.

The NMT debuts as a highly accurate, float-controlled sensor for continuous sensing of liquid levels. The instrument consists of two parts: a magnetostrictive sensor in the measuring tube and a four-wire transmitter with the connection box. The meter uses the principle of echo time measurement. A magnetostrictive wire is tensioned in the measuring tube and current pulses are transmitted through the wire that generates an annular magnetic field around the wire. The wire is then magnetized axially by magnets fitted internally to the float. When the magnetic fields align, a torsional impulse is generated, which propagates with ultrasonic speed in both directions. The distance from the float magnet to the predefined zero-point is measured by an echo time measurement. The NMT's electronics convert the time signal to a standard 4 mA to 20 mA analog signal.
