One time diagnostic or continuous vibration monitoring of rotative equipment mainly rely on analogic IEPE accelerometers which ask for dedicated convertor and cable to connect with Operational Technology network. Leveraging standard CAN or MODBUS protocol, digital based MEMS accelerometers connect directly to existing IIoT infrastructure which makes them easy to deploy on existing or new equipment.

Piezoelectric is a technology used for decades by accelerometer sensors designed for vibration measurement of industrial rotative equipment. They mainly rely on Integrated Electronics Piezo-Electric (IEPE) analog interface and ask for dedicated analog-to-digital convertor to connect with industrial Operational Technology network. Digital Micro-electromechanical Systems (MEMS) based accelerometers associated with microcontroller onto a simple embedded electronic provide digital interface compliant with IIoT protocols such as CAN or MODBUS RTU. They can directly connect with existing industrial IoT networks also used by PLC, be associated on a two ways daisy chain both for vibration sensor setting or data reading.
