The capaNCDT DT61x4 is an active, capacitive system for displacement, distance and position measurements. Consisting of a sensor with integrated preamplifier, a robust cable and a compact controller, the measuring system is immediately ready for use without any on-site calibration. The measuring system is available with a cable length up to 15 m and is ideal for automation purposes. The capaNCDT 61x4 is particularly suitable for automated robot manufacturing and measurement tasks with a drag chain. Moreover, it is used in machine building and semiconductor production. For optimum signal quality, the desired cable length is already factory-calibrated.

The capaNCDT 6200 is the first entirely modular multi-channel measuring system. The controller can be expanded to 4 channels and is therefore suitable for flexible applications. All capacitive displacement sensors from Micro-Epsilon can be operated using the capaNCDT 6200 controller. The integrated Ethernet interface supports parameter setting and measurements via web interface. The DL6230 demodulator provides high resolution measurements. For high-speed measurements up to 20 kHz, the capaNCDT 6222 system is available.

The new capacitive sensor system capaNCDT 6228 is designed for measurement tasks with ambient temperatures up to +800 °C. Up to four high-temperature sensors of the CSE/HT series can be connected simultaneously to the powerful controller. The integrated high-temperature sensor cable compensates for interference from electric or magnetic fields. Furthermore, the measured data is output both analog and digital via modern interfaces such as Ethernet and EtherCAT.

Capacitive displacement sensors are designed for measurement tasks that require extremely high precision. The capaNCDT 6500 capacitive multi-channel system is ideally suited to reliable measurements down to sub-nanometre resolution. The controller offers a maximum response rate of 7.8kHz (digital, with up to four channels) or a frequency response of 8.5kHz. As well as an analogue output, an EtherCAT interface is also available. EtherCAT enables accurate data transmission in real time, with high speed integration into the existing measurement environment and synchronisation of two systems. Set up and configuration of the capaNCDT 6500 system are carried out easily using a web browser.

Micro-Epsilon offers a comprehensive range of capacitive displacement sensors. These capacitive sensors are used for displacement, position and also for thickness measurements. Different sensor designs enable optimal integration into machines and systems. The capaNCDT sensors achieve best values in terms of linearity, temperature stability and resolution. While sub-micrometer precision is reached in industrial environments, even sub-nanometer accuracy can be achieved in clean environments.

Application examples are often found where the standard versions of the sensors and the controller are performing at their limits. For these special tasks, the measurement systems can be modified according to the customer’s individual requirements. Changes requested include, for example, modified designs, target calibration, mounting options, individual cable lengths, modified measuring ranges or sensors with integrated controller.

In its sensor housing, the combiSENSOR combines two displacement sensors. This unique sensor concept enables one-sided thickness measurement of electrically non-conductive materials on metallic objects. Its field of application is the thickness measurement of plastic film or of plastic coating on metal plates. The eddy current sensor penetrates the plastic layer and measures the distance to a metallic material underneath it, e.g. a metal plate. The capacitive sensor synchronously detects the distance to the plastic material. The thickness is determined based on the difference of both sensor signals.

The capaNCDT DTV series is designed for non-contact detection of Disc Thickness Variation (DTV). Capacitive sensors for multi-track measurements and a carrying case including the complete measurement channel for mobile use are available. With the capaNCDT DTV measurement system, capacitive displacement sensors determine the thickness of the brake discs from both sides based on the difference principle. While the brake disc rotates, the thickness deviation is determined via the circumference of the entire disc. Using several sensors in pairs or the CSH1,4FL multi-channel sensor makes multi-track thickness measurement possible. Thickness measurements can be carried out in test benches, in road tests or in car repair shops. The DTV case is intended for mobile use, e.g., for quality assurance purposes and warranty claims.

The capaNCDT MD6-22 capacitive dual-channel handheld gauge is used for mobile and precise measurement of gaps. This measuring device impresses with high accuracy, intuitive operation and long battery life. Thanks to preset measurement modes, the handheld gauge is immediately ready for use. Compatible with all capacitive sensors from Micro-Epsilon, the MD6-22 is used in different measurement tasks, e.g. for rotor gap monitoring in wind turbines and alignment of rollers in plant and machinery.

The optoNCDT 1220 is the entry-level model for precise measurements in industrial automation. This compact laser triangulation sensor measures displacement, distance and position with high precision. Based on an excellent price/performance ratio, this sensor is ideally suited to measurement tasks involving a large number of pieces. Therefore, the sensor can be used in all fields of automation technology, e.g., in machine building, 3D printers or robotics.
