KINAX WT720 - Aquisition of Angle of Rotation in Roughest Environment

Encoders with capacitive sensing systems belong to the best contactless sensor types with analogue output signals. The precision capacitor consists of two capacitor electrodes and a rotor between the same. The insertion of the rotor between the capacitor electrodes changes the capacity of the sensor proportionate to the absolute angular position. An oscillator generates a current between the capacitor plates which is proportionate to the angularity.

Camille Bauer AG has offered analogue capacitive angular position transmitters with an output of 4-20 mA in two-wire technology for may years. The advantages of the capacitive measuring principle are low energy consumption, robustness and a minor influence of interfering fields.

The 58mm housing diameter model has become standard in the angular position market. Previously, Camille Bauer AG could not offer an angular position transmitter in this segment. However, with the new KINAX WT720 the time has come. The capacitive sensor with an output of 4-20 mA in two-wire technology is installed in a robust and splash-proof aluminium housing with 58mm featuring protection class IP67 and IP69k. The robust, free-of-play bearing structure can take high radial and axial forces. It thus offers good protection against high temperature fluctuation, humidity, dirt, shock and vibration. Measuring range and direction of rotation may be programmed via a scanner and switch. Zero point and measuring span are independently adjustable. The programmability of KINAX WT720 facilitates planning and engineering work, shortens delivery periods and requires less inventory. The instrument is predominantly used in mechanical engineering and transport vehicle construction.
