The Geosense Wi-SOS 800 (Wireless Sensor Observation System) provides a system to remotely log and transmit signals from any sensor with a vibrating wire or 4-20mA output plus temperature.
It consists of a series of Wi-SOS 800 nodes (1-16 channels) which have an integrated wireless transmitter module which can transfer the data to a central location up to 8 km away.
Data from the nodes is collected via a fully configured Gateway where the data can be re-configured, accessed and manipulated by Wi-SOS NMS Software. Registering and configuring the nodes is done via two Memory Keys and can be easily done in the field.
Mounted in rugged enclosures with a heavy duty battery, the Wi-SOS 800 nodes are suitable for even the harshest environments. Powered by a heavy duty 12 volt battery with solar panel charging means that the Wi-SOS 800 is ideally suited to long term remote monitoring.
The Wi-SOS 800 provides wireless data transfer from sensors such as:
- Piezometers
- Strain gauges
- Load cells
- Total pressure cells
- NATM stress cells
- Rod extensometers
- Crack meters
- Joint meters
- Settlement cells
- Temperature sensors
- V-notch weirs
