PdM solution for dangerous, remote, and hard-to-reach assets

The Echo® Wireless Vibration Monitoring System is a simple, IIoT-enabled predictive maintenance solution that helps you monitor hard-to-access equipment—without risking technician safety or running expensive cables. It delivers critical vibration and temperature data directly to your monitoring system, so you can act on issues before they become failures.

No manual data collection. No long cable runs. Just smart, safe monitoring.




Field-proven across power generation, steel, food processing, paper, chemical, and automotive industries, the Echo® Wireless Vibration Monitoring System is ideal for assets where wired systems aren't practical.

Simple, flexible architecture for wireless vibration monitoring

The Echo® Wireless Vibration Monitoring System is designed for easy deployment across a wide range of plant environments:

  • Echo® Wireless Sensors – battery-powered and cable-free for flexible installations
  • EchoPlus® Wireless Junction Box – converts up to 8 wired sensors to wireless
  • Echo® Receiver – captures sensor data from long distances
  • Monitoring software – stores, visualizes, and integrates results with plant systems

Mix and match Echo® Wireless Sensors and EchoPlus® Wireless Junction Boxes to suit your layout, asset criticality, and budget. Need help designing your system? Our application engineers are ready to assist.

Remote machine monitoring with Extended Range RF

Echo® Wireless Sensors use Extended Range RF (ERRF) technology to transmit reliably—even in complex industrial environments.

  • Up to 1,200 ft (365 m) range indoors
  • Miles of range outdoors—no mesh networks or repeaters
  • Just 0.75 mW ERP for ultra-low power consumption
  • Seamless data integration via Modbus®, SQL, or ODBC

Ensure reliable connectivity while maximizing battery life and minimizing infrastructure needs.

Proven measurements for reliable fault detection

Echo® Wireless Sensors track RMS velocity, RMS acceleration, true peak acceleration, crest factor, and temperature — proven parameters for detecting imbalance, misalignment, bearing faults, gear issues, lubrication loss, and looseness.

Put Echo® Wireless to work in your facility

Whether you need a few sensors or plant-wide coverage, IMI offers tailored, scalable wireless solutions to keep your maintenance program proactive. For a consultation in your facility, contact us or request a quote today.
