TOWA Level Meter TSA-B4SA-045

Capacitive level switches have electrodes (ground electrode, detection electrode) and electronic circuits.
It is configured to be a capacitor. In addition, the ground electrode should come into contact with the tank.
Form a capacitor including the tank.
Conditions that determine the capacitance value of a capacitor include shape, dimensions, arrangement, and ambient conditions.
If the conditions other than the relative permittivity (* 1) of the measured object are the same, it depends on the difference in the relative permittivity of the
measured object.
Determines the capacitance value of the capacitor.
Based on the capacitance value when the object to be measured is air, it depends on the object to be measured with a different relative permittivity.
You can determine the difference from the capacity value that can be created. In addition, two objects with different relative permittivity
It is also possible to distinguish between two measurement objects by using one as a reference.
This product detects the capacitance value of the measured object and outputs a signal.
