ElasitSense EDS capacitive displacement sensor

Click2Contact

The ElasitSense EDS sensor is a contact capacitive displacement sensor. The sensing element is made of a hyper-elastic elastomer stretchable strain gauge. It comprises dielectric sheet and deformable electrodes. During operation, the sensor is stretched by a machine or a structure which produces a change in capacitance. The displacement value can be calculated based on this change.

Unlike other piston-based displacement sensors, the EDS sensor offers capabilities to measure both linear and off-axis measurement. It also has robust and flexible design that is highly resistant against shock, vibration and installation misalignment. Due to this, the sensor is suitable for application in harsh industrial environments with minimum costs. This low-cost sensor also has no sliding parts in its design, further reducing its installation and maintenance costs.

The EDS series contact capacitive displacement sensor can be used either as a standalone or as a part of the system together with the other daisy-chained sensors. The sensor generates analog output as current, 4–20 mA or as voltage, 0–10 V, on request. It can also be provided with an RS485 interface. With a fast measurement rate up to 10 kHz, this EDS sensor is suitable for fast and dynamic measurement tasks. Measurement range is 20–200 mm with an accuracy of 0.1% FS.

This technology is suitable for metal forming applications. It is commonly used to detect faulty operations of stamping tools due to the presence of metal slugs. Other potential applications include process automation, structural condition monitoring, predictive maintenance and R&D.
