TWM System

TWM System – Bridge Displacement Measurement System

TWM System

We use TWM system to calculate deflection of bridge easily and accurately. Traditionally, measurement of “deflection” was difficult to measure because it was difficult to set fixed points in the case of a river under the bridge.

In the proposed “TWM system”, since acceleration is used, it is possible to measure by merely installing the device at the measuring point. In addition, since we realized complete automation of operations requiring setting and adjustment by engineers, anyone can do it, and anyone can provide the same result. As a measurement service, I am considering renting equipment every time.
