Bridge safety monitoring
With the development of national economy, more and more super large bridges come into people's view. The bridge structure is gradually developing to light and slender. At the same time, the load, span and deck width of the bridge are growing, and the structural type is changing. These transportation infrastructures play an important role in people's economic life. Long term health monitoring of bridge is an important link to evaluate the health status of bridge, ensure the safety of bridge and avoid accidents. Monitoring bridge deformation can effectively reflect the working condition of bridge structure and provide reliable data basis for the corresponding management departments. Therefore, it is a long-term work to provide bridge health early warning by deformation monitoring, which is of great significance.
Our sensors can provide rich data information for monitoring software.
Real time acquisition of the real-time changes of the displacement of the monitoring points at the characteristic parts of the cable tower and bridge deck
By analyzing the displacement change of monitoring points, the operation law of bridge in various environments is obtained
Evaluate the health and safety of the bridge structure, and comprehensively obtain the information of the bridge operation status, so as to evaluate the safety, durability and usability of the structure.
Display the change of bridge displacement through data and 3D model
Provide important data for verifying bridge design and load design evaluation

374A Seismic accelerometer ,20V/g high sensitivity vibration sensor
V374A Seismic accelerometer ,20V/g high sensitivity vibration sensor:Model 374A is specifically designed to enable the detection of ultra-low level, low frequency vibrations associated with very large structures, foundations, and earth tremors. The sensor typically possess exceptional measurement resolution as the result of a comparatively large size, which furnishes a stronger output signal and a lower noise floor. Both ceramic and quartz sensing elements are utilized in seismic accelerometer designs. The 374A with ceramic sensing element, offers the best low frequency response. Build-in low noise signal conditioning circuitry offer the greatest measurement resolution. For the best measurement clarity, seismic accelerometers should be used with a unity gain, battery powered signal conditioner. The accelerometer offer rugged, laser welded, stainless steel housing with durable military style connectors. Electrical case
isolation, hermetic sealing, RF, EMI, ESD, and overload protection all ensure tolerance against environmental influence and mishandling. All variations provide reliable measurements and long-term stability.
