onitoring Solutions are the natural choice when you need to monitor railways, earthworks or geotechnical movements. 1 9 8 6 2 1: PIEZOMETER The Vibrating Wire Sensor Node supports a variety of interface sensors such as crack, strain gauges and extensometers. Here it is connected to a piezometer and prevents the need for manual logging by transmitting data on pore water pressure and groundwater level variations. 2: TRIAXIAL TILT NODE Wireless tilt sensors are mounted on stakes which are driven into the face of the slope. The sensors detect rotational movements within the geotechnical structure and can be set to trigger automated alarms and accelerate sampling when pre-set thresholds are breached. 3 3 5 4 3 7 10: CRACK SENSOR The Crack Sensor node is used to monitor structural movement including crack movement, expansion joint movement and pile separation. Here it is monitoring the movement of a crack on the tunnel headwall. 9: FLEXIMEASURE 5: TEMPERATURE SENSOR The PT100 RTD Sensor Node enables precise temperature monitoring and critical rail temperature alerting. Can be supplied with an integrated High-G triaxial tilt sensor for combined tilt and temperature monitoring. FlexiMeasure is a lightweight Inclinometer that can be installed in any orientation; segments can be connected to form a chain of flexibly coupled triaxial sensors. Here it can be seen measuring/monitoring changes in the profile of the tunnel wall. 8: OPTICAL DISPLACEMENT SENSOR (ODS) The ODS combines a tilt meter and a laser displacement sensor. Together they 3: NANO TILT NODE Wireless tilt sensors installed on trackbed can measure rail track heave/ differential settlement, cant and twist. With no external antenna and a durable shell, the Nano is ideal for the most challenging environments. 4: MILLIVOLT The Millivolt Sensor Node enables a variety of structural and geotechnical sensors to be integrated into a wireless monitoring system. Strain gauges on trackbed are just one example. A node cap helps to protect the antenna. provide information about the stability of the structure the sensor is fixed to and relative movement of a target structure. Here it is measuring convergence of the tunnel intrados. 6: 4G CAMERA The FlatMesh 4G Camera is a high resolution camera that is able to take great quality black and white photos of your site day or night. The camera can be set to take photos at regular intervals, on demand or, when triggered by movements detected in nearby sensors. 7: 4G GATEWAY The FlatMesh 4G Gateway provides all the functionality required to operate a wireless sensor network in a remote location. With a solar panel, no fixed power supply is required. Data is transmitted from the sensors to the Gateway and onwards to a secure cloud-based server and data management platform. 10 Geofix are proud suppliers of Senceive’s Remote Monitoring Solutions.
