Capacitive sensors are considered only suitable for clean and dry environments. However, Micro-Epsilon's industrial capacitive sensor has also impressed people in battery applications. They can achieve submicron accuracy even in challenging environments.
With its temperature resistance, robustness and flexibility, capacitive sensors can be used in environments with temperature or magnetic field fluctuations.
Capacitive sensors reliably measure displacement, distance and position with submicron accuracy. They are preferably used in high-precision fields, such as battery production.

Capacitive sensors reliably measure displacement, distance and position with submicron accuracy. Among other things, they are also used for online applications, such as film thickness or adhesive application measurement.
Double-sided thickness measurement of conductive materials
In battery production, the thickness measurement of battery film is very important. Two relatively installed capacitive sensors can measure the thickness of both sides. This method can be used to measure the strip thickness within the range of µ m. Each of the two capacitive displacement sensors provides a linear distance signal, which is calculated by the controller as the thickness measurement value. The measuring point of the sensor is larger than that of the optical method, which can average out any structure and abnormality on the surface. Using the capaNCDT multi-channel controller, you can use only one controller to process multiple sensor pairs.

Double-sided thickness measurement of stable mounting bracket
The mounting frame can be used for multi-track thickness measurement using capacitive sensors. This framework can achieve more accurate measurement results, and is used for double-sided thickness measurement of battery and diaphragm in the battery industry. The sensor is precisely located on a shaft here, so it is consistent. A maximum of six sensors can be installed in one mounting bracket. Since two sensors can image one measurement point, at most three measurements can be made at different points simultaneously. The mounting frame is very stable at temperatures up to 100 ° C.

Ideal for confined space: capacitive PCB sensor with patented micro connector
Micro-Epsilon provides extremely thin PCB-based sensors for these limited installations. These sensors have a height of 14 mm or 25 mm and are equipped with miniature triaxial connectors. The cables, sensors and connectors here are almost the same size. The connector is only 3.6 mm, about three times smaller than the traditional connector. This greatly simplifies the integration of sensors in machines and systems with particularly narrow installation space. The spiral sheath of the used cable provides additional protection against damage.

Achieve accuracy through three-axis design
Unlike traditional capacitive sensors, Micro-Epsilon sensors are not coaxial, but triaxial. This means that, in addition to the shell, the capacitor is also surrounded by a protective ring with separate power supply between the capacitor and the shell, thus generating an electric field. This creates a uniform field between the measuring electrode and the object surface. The protective field around the measuring electrode can prevent the field from spreading to other nearby conductive objects or other areas of the target. It can prevent other objects from affecting the measurement. This three-axis design makes the sensor stronger and more accurate. The linearity is significantly improved and the interference of the measuring field is reliably prevented. In addition,
Two measuring principles - one sensor
The capacitance measurement principle is also very suitable for use in combination with other measurement methods. Based on this, Micro-Epsilon developed combiSENSOR, which combines capacitive and inductive sensors on the basis of eddy current. In battery production, it can measure non-conductive strip materials such as coating. The sensors integrated in the sensor housing measure the distance from the same side to the aluminum roll. The capacitive sensor uses the dielectric constant of the non-conductive material to determine the distance to the top of the strip. The eddy current sensor determines the reference distance from the guide roller. In addition to high accuracy, high temperature stability is a decisive advantage. This means that thickness measurement can also be carried out in the dry coating process, for example.
