The LMT200 is based upon the magnetostrictive principle.

  1. The device electronics generates a low energy current pulse at fixed intervals.
  2. The electrical pulses create a magnetic field which travels down a specialized wire inside the sensor tube.
  3. The interaction of the magnetic field around the wire and the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire.
  4. A patented sensing element placed in the transmitter assembly converts the received mechanical torsion into an electrical return pulse.
  5. The microprocessor-based electronics measures the elapsed time between the start and return pulses (Time of Flight) and converts it into a position measurement which is proportional to the level of the float.
