Charge Mode Accelerometers for Harsh Nuclear Environments

Proven sensors for nuclear power plant condition monitoring

IMI Sensors has decades of experience supporting nuclear power generation with precision-engineered, radiation-hardened sensors. Our charge mode accelerometers are designed to deliver reliable vibration measurements in the most extreme environments—high temperature, high radiation, and high reliability demands. With proven performance in nuclear applications around the world, IMI products help operators monitor turbine generators, cooling pumps, motors, and other critical assets under the toughest conditions.

Radiation-hardened sensor technologies for nuclear reliability

Vibration monitoring in nuclear power plants requires extremely resilient sensor technology. Our charge-mode accelerometers have no internal electronics and are made with robust materials for long-term installation in radioactive and high-temperature zones, ensuring dependable diagnostics over decades.

  • Radiation-hardened design: No internal electronics—ideal for high-radiation zones
  • Charge mode output: Electrostatic signal output unaffected by radiation
  • High-temperature operation: Withstands thermal extremes without performance loss
  • Ideal for long-term installations: Durable materials built for years of exposure
  • Low-maintenance operation: Minimal drift, high signal stability
  • Expert guidance available: Application engineers ready to help specify the right sensor
