1. Product Introduction
The WiSenMeshWAN
®
Vibrating Wire (VW) Interface Node is one of the key products in our
patented WiSenMeshWAN
®
geotechnical safety monitoring system. Working together with the WiSenMeshWAN
®
gateway product and our customers VW type sensors, it intelligently delivers the real-time VW derived deformation of
the structure to the information centre.
The WiSenMeshWAN
®
VW Interface Node operates using our core technology, i.e., the WiSenMeshWAN
®
Low Power,
Intelligent, Wireless Sensor Network protocol, together with its internal high precision frequency sampling module and
power unit. This interface node is compatible with conventional geotechnical vibrating wire type sensors measuring in
the range from 400 to 6000Hz. This product satisfies the three fundamental identities of the system:
A. Network Life Span: to maximise battery life across the mesh network as a whole;
B. Network Data Arrival Rate: to minimise data packet loss;
C. Single Node Environmental Coverage: to maximise radio coverage.
Our product has IP66 and is designed to work in a tough environment. It is small in size, reliable in performance, easy
for maintenance, has high precision during sampling, and has strong immunity to radio-interference.
Figure 1. 4-Channel VW Interface Node Overview.
WiSenMeshWAN® VW interface node is Compatible with all different brands & types of high quality Vibrating Wire
sensors, therefore it can be applied in all different related monitoring projects. Examples of VW sensors: Strain Gauge;
Displacement Transducers; Piezometers; Settlement Sensors; Pressure Cells; Load Cells.
