Senceive GeoWANModel PDS-LR3N-LDS -Optical Displacement Sensor Node

SHARE

The GeoWAN Optical Displacement Sensor Node is an instrument which uses optical means to take high precision displacement measurements and pass these through Senceive’s GeoWAN wireless communications network to a GeoWAN Gateway. It can also be combined with Senceive’s worldleading triaxial tilt sensor to obtain high precision tilt measurements that are linked to an external reference.
