Abstract

The invention relates to a remote sensor for use in detecting integrity in structures and more specifically pipes. Examples of existing sensors are able to detect so-called defect characteristics that are encountered in corrosion products that are found in pipelines and originate from pipe walls. In one embodiment the invention provides a sensor adapted to be located on a structure. The sensor comprises a sensing element capable of providing a signal to a microprocessor. The microprocessor is adapted to run software in order to evaluate signals in order to indicate a status of the structure. A communication device transmits a signal to a remote recipient. Energy for operating the sensor is derived from a vibration emission array which is in contact with the structure. Thus the sensor is able to detect vibration, temperature and other variables, convert these signals into recognisable data and alert a remote location in the event of a hazard or fault. The sensor is also able to perform other functions such as self-testing, remote interactive training and self-updating of upgraded software and control systems.
