Details: LMC-Ex

Function

The device is a sensor for continuous level measurement in liquids.

A ring magnet integrated in the float activates a reed contact resistance chain inside the probe tube via its magnetic field.

If the level changes, the resistance chain changes its total resistance by closing the contact at the float level. The resistance is converted into a standardised output signal by a control unit. This output signal is proportional to the level of the measured medium.
