SENCEIVE - Sensor interface for crack sensor
Senceive's sensor interfaces enable the integration of numerous geotechnical and structural monitoring sensors from both Senceive and third-party suppliers into remote WCM systems.
The crack sensor can be used to monitor structural movements such as cracks in bored pile walls, the propagation of cracks and the movement of expansion joints.
The crack sensor forms the interface to a linear displacement sensor (potentiometer). It controls the scanning and simultaneously supplies the sensor with power.
The measured values of the external crack sensor (potentiometer) are transmitted wirelessly to the gateway via the sensor interface (crack sensor node).
It has already been used successfully in many applications, including the measurement of:
