Capacitance Level Sensor

 
→ Capacitance Level Switch, type YSA

 

YSA, Capacitance level switch

The capacitance level switch measuring principle is based on the "capacitance
effects".

When this level switch is set on a silo, it will form a condenser between
the detector electrode and the silo wall.

The capacitance of this condenser varies proportional to the change of material
specific inductivity (DK value) of the material stored in the silo.
When the material substances increased in the silo, the capacitance value added
simultaneously, then it will let his interior circuit's resonant signal to create
a bigger amplitude, and such a signal amplitude become more or less than factory default threshold value, the relay device will be energized.
The capacitance value increases as the dielectric increases.
Therefore capacitance is proportional to dielectric.
