Two linear displacement sensors from Bestech Australia are being used to monitor important structural elements of bridges and transmit data to a remote data logger in real time.

Monitoring aging transportation infrastructure and effects of increasing traffic loads on bridges can be challenging. Contemporary technologies allow bridge monitoring to be done electronically, enabling the structures to be maintained and repaired before any structural integrity problem could develop.

Civil engineers have become fully aware of the cost advantages of using sensors in evaluating infrastructure condition. The cost of instrumenting a typical bridge can quickly offset the expense of periodically sending an experienced inspection crew to the bridge.

The LV-45 and LV-48 series linear position sensors from Bestech Australia are used to monitor the structural integrity of bridges in bridge health monitoring systems. Rated IEC IP67, the sensors have built-in electronics that operate over a wide temperature range.

Featuring aluminium and stainless steel housings, a variety of mounting hardware, and cable or connector electrical terminations, these sensors give an analogue output of a high-level DC voltage or a 4-20 mA current loop, either of which can easily connect to any data acquisition system for continuous monitoring and/or data transmission over a remotely accessible wireless network.
