Bently Nevada 70M303 121M6469 Wireless Sensor

The 70M303 121M6469 wireless sensor from Bently Nevada monitors machine vibration and temperature without field cabling. Plant engineers deploy this sensor on pumps, motors, and compressors where routing wires would prove costly. Consequently, it delivers continuous condition data to the gateway across the plant network.

Functional Overview

This sensor captures vibration and temperature readings and transmits them over a wireless link. Therefore, it removes the need for long cable runs to every measurement point. The 70M303 121M6469 also stores data locally until the gateway confirms receipt. Meanwhile, its internal energy storage keeps transmissions stable during peak power demand.

Installation and Handling Notes

Always prepare a clean, flat surface before mounting the 70M303 121M6469 onto machine housings. In addition, apply the specified torque to the mounting stud. Keep the sensor away from large metal structures that block radio signals. Finally, confirm signal strength after installation.
