The EDS sensor is a contact capacitive displacement sensor that can be used either as a standalone or daisy-chained system. During operation, the sensor operates by being stretched which generate change in the capacitance. Based on this change, the displacement of the structure or object can be calculated. It has a flexible design enabling both linear and off-axis measurements in all three directions. The sensor itself is robust and capable of withstanding high level of shock and vibration. It also offers low cost alternative due to the absence of the sliding parts in the sensor. With low installation and maintenance costs, the EDS sensor is a cheap alternative to the LVDT’s.
The sensor is also available as a plug and play autonomous data collection system. This can be achieved through connecting one or two EDS sensor to a data acquisition unit. This Portable Test Kit (PTK) offers precise measurement to the user without having to invest in a large system.

The EDS sensor has a capacitive sensing element that is made of a hyper-elastic, stretchable elastomer strain-gauge. When stretched by a machine or a structure, the sensor will produce a change in capacitance. This change is measured and converted to displacement.
