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.
