AT11610 is a level and environmental sensor that has been specially designed to offer high-precision volume and leakage monitoring.
The AT11610 sensor operates in accordance with the magnetostrictive measuring principle.
The sensor tube contains a wire made of magnetostrictive material. Magnets integrated in the floats magnetise the wire at the float position.
The sensor electronics transmit current pulses through the wire, which generate a circular magnetic field. A torsional wave develops at the point where the two magnetic fields overlap and it propagates towards the sensor head. In the sensor head, these waves are converted into an electrical signal.
The float positions and the temperature are calculated from the different propagation times.
