Sensor technology for monitoring of pressure safety valves
CMR has been the main technology partner for Sentec in developing low cost wireless smart sensor technology for monitoring of pressure safety valves (PSVs). CMR's work in the project includes the development and programming of a low cost sensor, an accompanying Android App communicating with the sensor via Bluetooth and a cloud server solution.
PSVs are critical safety devices that act to protect equipment and personnel in the event of dangerous pressure build-up in process piping and vessels. The smart sensor developed in partnership between CMR and Sentec detects when a PSV has been exposed to an overpressure event. This information is received by an App running on a rugged, industrial Android phone via Bluetooth, from where the information is relayed to a cloud server.
The algorithms for detection of PSV overpressure events are deployed directly to the smart sensor and are based on analysis of high frequency data from an inertial measurement unit (IMU) integrated in the sensor. The algorithm development builds on CMRs platform for monitoring of movements using IMU data, which is a part of CMRs smart sensor initiative.
