1. Capanivo ® CN 4000 The best in its class!! Capacitive Measurement by UWT

2. Technology: What is capacitance? Capacitance is the ability of a body to store charge in an electric field. Capacitance can be calculated if the geometry of the conductors and the dielectric properties of the insulator between the conductors are known. A - is the area of overlap of the two conductors; ε - is the relative static permittivity = dielectric constant of the material between the conductors (for a vacuum / air, ε = 1); d - is the separation between the conductors. C = ε · A d

3. Technology: What is capacitive measurement? A general technical explanation of capacitance switches The functionality of the capacitance switch is based on the change of the electric field between “ground” and “active”. The capacitance change between these electrodes is measured. With the material reaching the active zone of the sensor, the capacitance raises thus influences the oscillating amplitude of the RC-oscillator. The sensitivity of the sensor varies enormously according to permittivity, size of the sensor, material and mass. ε groun d activ e shiel d

4. Build-upActive shield Technology: Capanivo CN4000 with active shield Active shield protects against build-up on the probe and compensates for its effects so that the switch point is always accurate. Active shield creates a second electric field, that prevents direct connection between sensor electrodes. The effect of active shield depends on: the thickness of the build-up on the probe, conductivity of the material, the sensitivity setting.

It is a spezific constant of the rate of polarizability of a solid or liquid. If this rate is higher, all the more is the capacity of itsself. Generally materials with a higher density also have a higher dielectric constant.
