Getting on track

Senceive has focused on wirelessly monitoring assets for the rail and construction industries as well as the built environment since its inception in 2005. One of Senceive's core application areas is measuring the long-term tilt and crack movement on structures. The company's meshed systems of wireless sensors are used to assess the condition of buildings both inside and outside, structures, embankments, bridges and other rail signaling related assets. Senceive's wireless sensor networks are easy to set up and comprise highly sophisticated embedded systems. The network is integrated with sensor types that can be affected by the physical environment at the point of deployment. Initially the company needed NPL's help to improve its tilt sensing system and verify its accuracy, precision and limits. NPL characterized the output of Senceive's tilt sensors in terms of linearity, jitter and overall uncertainty. NPL also advised Senceive on system improvements and on future deployments.
