Decentlab LoRaWAN Vibrating Wire for Strain or Weight 830-4018 EU868

An oscillating wire sensor is used to convert the force/load into an electrical signal, which is then communicated over radio waves to a Decentlab base station, providing real-time data. It can be easily fixed on the structure to be surveyed and allows a precise and reproducible measurement of its stress changes. Using vibrating wire technology instead of a strain gauge, means having a simple mechanical mounting combined with a very accurate measurement.

Key features highlights :

Application Surveying the stress of any kind of structure like bridges, cranes, machines or tanks. 

This technology also offers an extremely high resolution. Deformations of fractions of a µm can be measured. 

Since this sensor is adapted to the material of the structure to be surveyed, differential thermal expansion has no negative influence on the precision. The technology offers very good long-term stability. Since no organic material is involved in the measurement chain, creeping or other influences are reduced to the minimum.
