SenSpot - Wireless Strain Gauge

10+ Years Battery Life

• without battery replacement

High Precision

• 1-µStrain resolution

Easy Installation

• self-adhesive(e.g. steel)/
• flange-mount(e.g. concrete)

Long Wireless Range

• 1 km free space

Quick Testing Available

• easy to reuse in other places

High Sampling Option

• record unusual strain event

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

• 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
