Wireless Strain Gauge SenSpot™ Sensor

Description

Wireless Strain SenSpot™ sensors offer a breakthrough technology for real-time and long-term structural health monitoring.  SenSpot™ strain gauge uses Resensys’s proprietary sensing, scheduling and ultra-low power synchronization technology. SenSpot™ is designed to operate maintenance-free for more than a decade. After installation, SenSpot™ does not need calibration, battery replacement, or any other maintenance during its entire service life.

Features

• Long lifetime: (minimum expected life without battery replacement 10 years)

  • Self-adhesive, no drilling is required (e.g. steel)
  • Flange-mount, drilling is required (e.g. concrete)
  • Quick installation, 1-2 minutes
• High accuracy: 1-µStrain resolution
• Wide working temperature: -40 to +65°C (-40 °F to +150°F)
• Long communication range: 1.0km free space
• Small size:
  • Wireless transmitter: 50mm (1.96”) x 50mm (1.96”) x 34mm (1.34”)
  • Strain Gauge sensor: 76.2mm (3”) x 33.4mm (1.30”) x 10mm (0.4”)
• Complementary sensing: temperature, battery voltage, etc.
• (Optional)High sampling rate; instant data transmission triggered by strain spikes:
• A balance between power consumption and performance.
• Perfect for detecting event and recording the waveform of a sudden strain change
• The triggering threshold is adjustable from 16µStrain to 512µStrain; the sampling rate can be changed from 10ms to 200ms

Applications

• Long- term and continuous monitoring of strain (stress)
• Detecting short-lived and transient high-strain events, e.g., caused by fast moving trucks on highway bridges or by turbulence on airframes
• Fatigue awareness, fatigue life analysis (remaining useful life estimation)
• Fast, easy-to-install adhesive mount
• Examples applications:
  • Highway bridges
  • Airframes
  • Pipelines
  • Machines, cranes, etc.
  • Truck tests, bridge load rating
