Wireless Monitoring System

WiSenMeshNET 1/4-Channel Vibrating Wire Interface Node

This internally powered sensor node allows integration with upto eight vibrating wire sensors. With wide frequency  range (400~6000Hz) and very high accuracy (±0.015%) and precision (±0.002Hz@400Hz or 0.05Hz @6000Hz). 

The nodes automatically excite the vibrating wire in the connected devices at required intervals and collate data for the frequency (Hz) and resistance (KΩ). 

The node can have multiple channels for sensor input, an integrated temperature sensor and wireless mesh radio transmitter via the external antenna. 

The battery lifespan is up to 15 years for 1 Channel and 17 years for 4/8 Channel versions at  hourly readings.
