Scalable Solutions

Each Machine Condition Monitoring System (MCM) computer or Collection Server can host many Receiver Nodes and each receiver can be configured to collect data from 100 sensors, enabling a single Machine Condition Monitoring System to monitor hundreds of machines with multiple sensors on each. This gives you the ability to scale your predictive maintenance system to the size of your plant, no matter how large or small it is, and to grow as your company grows.


Receivers are powered and communicate via USB with their host computer or Collection Server. Each receiver can simultaneously collect information from many sensor nodes, increasing system efficiency and keeping implementation costs low.


SmartDiagnostics® wireless receivers and sensors coexist with no interference with your existing wireless networks due to their small data packet size and extremely low overhead, making them easy and economical to install and operate in a wide variety of industrial settings.


  • Very efficient wireless transmission protocol enables very rich sensor data collection using minimal power and bandwidth.
  • Easy, highly configurable sensor network structure simplifies system implementation and management.
  • Robust industrial-grade design of the Receiver Node allows the nodes to be deployed in harsh industrial environments.
  • Total cost of ownership is minimized through a combination of affordable Receiver Nodes plus easy implementation and management.
