Introduction
The capacitance between the active electrode of the sensor and the electrical earth potential is measured. An approaching object influences the electrical alternating field between these two ”capacitor plates”. This applies to metallic and non-metallic objects. In principle, capacitive sensors work with an RC oscillator. A very small change in capacitance is enough to influence the oscillation amplitude. The evaluation electronics converts this into a switched signal. The sensitivity can be set with a potentiometer.
ifm electronic
ifm electronic gmbh is one of the leading manufacturers of automation technology world-wide. More than 3,000 employees in more than 70 countries develop solutions for 80,000 customers in the manufacturing industries. By optimising technical processes in the automotive, chemical and cosmetics industries or in environmental technology and automation of buildings ifm electronic has consistently set new standards and thus ensures tomorrow's production processes.
The family-run company with headquarters in Essen started with the invention of inductive proximity sensors in 1969. The German production in Tettnang on Lake Constance has ensured brand quality right from the start. Today "efector" stands for position and fluid sensors, object recognition, diagnostic and identification systems. The brand "ecomat" is synonymous with networking and control systems. In 2007 ifm made a turnover of more than € 410 million with above-average product quality, exceptional innovations and consistent close contact to the customer.
