Bestech Australia present the capaNCDT 6350 high-speed capacitive displacement sensor system from Micro-Epsilon. The capaNCDT 6350 is a compact, single-channel system that comprises a capacitive displacement sensor, a sensor-connecting cable and signal-conditioning electronics. The capaNCDT 6350 capacitive displacement sensor systems are available in Australia and New Zealand from Bestech Australia.
The capaNCDT 6350 exhibits high measuring rates with a bandwidth of up to 50kHz with high stability and accuracy and nanoresolution. The sensor operates on a similar principle to the ideal parallel plate capacitor. The sensor and opposing target represent the two plate electrodes of a capacitor, and the amplitude of the AC voltage on the sensor is proportional to the distance between the capacitor electrodes.
These capacitive displacement sensors are designed for industrial use in production plants and measuring and testing operations during in-process quality assurance. This could include distance, vibration, deflection, stroke or dimensional inspection. The capaNCDT 6350 is suitable for all electrically conductive materials.
The capacitive displacement sensor system uses a unique active driven and hermetically sealed triaxial RF cable in conjunction with an active guarded tri-electrode sensor. Therefore, the system is electron leakage proof and creates a protected homogeneous measurement field enabling a stable, interference free precision measurement. Any parasitic capacitance which compromises the accuracy is eliminated.
Measuring ranges of between 0.2mm and 10mm are available. Linearity is less than 0.3% of the full scale output, while resolution varies from 0.005% FSO to 0.1% FSO depending on the frequency. Temperature stability is below 0.01% FSO/°C, while long term stability is below 0.02% FSO/month. Output is given as 0V to 10V DC voltage, while a 9V to 30V DC (5.5W) power supply is required. The Micro-Epsilon capaNCDT 6350 sensors can operate in temperatures from -50°C to 200°C.
