Measurement module with vibrating wire sensor

Back
Measurement module with vibrating wire sensor

Description

The module allows static and dynamic measurement of a number of 8 vibrating chord sensors and 8 corresponding temperature sensors.
It can be used for new monitoring systems or for existing sensors, which are already included in structures (dams, foundations, tunnels).
It can be used independently or in combination with other types of modules.
The connection with the monitoring center is made with a single cable through which data transfers, synchronization and powering of the device are performed.
