4 FUNCTIONL DESCRIPTION Capacitive sensors detect metallic and nonmetallic, solid and fluid materials. They are used for object counting tasks, fill level measurement or for the detection of positions and objects. The functional principle of capacitive sensors is based on the variation of capacitance in the active field of the sensor due to the approach of the target. This active field consists of two electrodes. The design of the electrodes can be adapted to the design of the sensor. Illustration shows electrodes in concentric arrangement. electric field lines active field of the sensor (front view) electrodes electric field lines electrodes (capacitor) Functional principle opened capacitor plates pplication in capacitive sensors Illustration : rrangement of electrodes in capacitive sensors The approach of a target on the active field of the sensor causes a variation of capacitance in the electric field of the sensor (illstr. ). There are two different working principles for capacitive sensors Principle uses the damping of the electric field which is caused by the target. The target withdraws energy from the field. The degree of this loss of energy depends on the relative permittivity of the targets' material. The bigger this constant, the more energy is withdrawn from the field. The electronics in the sensor registrates this variation and switches when a certain threshold is attained. Principle 2 is based on the stimulation of vibrations in a RCoscillator by the approach of the target. The oscillator excites a highfrequency oscillation. When an object enters in this electric field the relative permittivity and the vibration behaviour of the oscillator change. The electronics in the sensor evaluates the emerging vibration and switches the sensor on, when a certain threshold is exceeded. Capacitive sensors from Pulsotronic are available in N and Pswitching design and as normally closed or normally open contact. The sensitivity for different target materials and environmental conditions is adjusted via a potentiometer. The realisable switching distance depends on the target material. 5

5 PPLICTIONS Fill level measurement Measuring fill levels capacitive sensors provide a yes/no statement about the presence or absence of the test material. Targets can be fluid, powdery or granulated. Sensor is situated outside of the filling zone and does not switch. Sensor 2 is situated below the fill level. The presence of material causes an activation of the oscillator. The sensor electronics evaluates that and switches. This arrangement allows a minmaxanalysis. The interconnection of further sensors enables to user to achieve a finer grading of his measuring results. The sensors can be mounted in nonmetallic dividing walls. In metallic dividing walls non mounting is required. Sensor (max.) Fill level Sensor 2 (min.) Dividing wall Material (fluid, powdery) Sensor Conveyor belt Test objects Counting tasks The target entering in the electric field of the sensor causes a variation of the capacitance. The oscillator is excited respectively energy is withdrawn from the field. The sensor switches. When the test object leaves the sensing range, the oscillator takes its' normal value. The bigger the relative permittivity of the target material, the bigger the realisable switching distance in the application. The capacitive sensor provides unspecific, not materialrelated information. statement concerning material, dimension or surface characteristics of the target is not possible with capacitive sensors. Detection of positions Objects moving in front of the sensor are detected when they reach a certain position. When the object enters in the electric field, the capacitance changes in dependence of the relative permittivity of the target material. The sensor switches. Sensor Moving target (e.g. slide mounting) 6
