High resolution:
The sensor with opto-electrical strain measurement

ESR strain sensors deliver notably higher measurement accuracy compared with foil-based systems:

  • Strain down to 0.025 µε
  • Vibration up to 30 kHz

Benefit from this added accuracy, especially when measuring dynamic loads. You can even measure and analyze short-term events such as load peaks from a single tractor trailer driving over a bridge.

Digital measurement data and more:
Fast and lossless data transmission over long distances

ESR sensors provide fast, reliable, and long-distance transmission of strain, vibration, and resonance measurements, but that’s not all. Their bidirectional digital interface also lets you leverage other key data for structural health monitoring:

  • Sensor diagnostic and status data
  • Acceleration and temperature data from external sensors

Maintain a complete overview of your investment and the status of your monitoring sensors.

Versatile mounting technology
for any application

Benefit from versatile measurement with ESR strain sensors, wherever and however you need the data:

  • Adhesive mounting for permanent installation
