3. Operating Principle
HITROL’s HTM is an innovative, multipurpose switch and has the simplest structure.
HTM sensor head is composed of one module which has an oscillating coil generating frequency
and a sensing coil detecting oscillation.
When the material inside the vessel does not exist around the sensing rod, the sensing rod
continuously vibrates due to the oscillating coil.
