Gefran Sensormate System for strain measurement with Bluetooth


The QE2008-W wireless strain sensor, featuring a magnetic mount, offers precise strain measurements at the point of installation, ensuring a level of accuracy and performance comparable to that of bonded strain gauges. Utilizing Sensormate’s innovative press-on technology, the strain gauge is strategically positioned beneath a durable stainless protective film. When the sensor is mounted on a metallic object, the magnets hold so strictly that frictional contact occurs and allows a reliable measurement.

  • Wireless system for strain measurements with Bluetooth 5.0
  • Press-on strain gauge technology (quick and non-destructive mounting)
  • Easy mounting via magnetic holding on flat and round surfaces (diameter ≥ 45mm)
  • Visualization of the measurements via the “Sensormate App” (available for Windows, Android, and iOS)
  • High performance amplifier integrated in each sensor with high resolution and fast sampling rate.
  • Integrated LiPo battery with long operating time (> 12h)
