The ifm efector VW Series Wireless Vibration Sensor is a compact, intelligent sensor designed for industrial condition monitoring. It intermittently transmits root mean square vibration velocity (v-RMS) and temperature data to a gateway via a proprietary mesh protocol, enabling early detection of machine faults such as imbalance, misalignment, and bearing wear. This allows for predictive maintenance scheduling before major failures occur .

The VW Series sensor features rugged construction with an IP68 protection rating, making it suitable for harsh industrial environments and washdown applications. It measures vibration across three axes with a measuring range of ±16 g (or 0-25 mm/s) over a frequency range of 10 to 1000 Hz, with an accuracy of ≤ 10% . For flexible integration, the gateway can connect to IT environments via Ethernet TCP/IP or Wi-Fi, and also supports network-independent communication options based on NB-IoT, LTE CAT M1, or 2G GSM mobile radio standards .

Powered by battery operation, the sensor is easy to install without the need for complex wiring, making it ideal for retrofitting on existing equipment. Its ability to provide continuous, wireless data on machine health makes it a valuable tool for improving overall equipment effectiveness (OEE) and reducing unplanned downtime in manufacturing and process industries.
