Bridge strain gauge transmitter SenSpot™

cellular IoTWLANwireless

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) •Lightweight： about 147 g (5.19 oz.) •Wireless transmitter: 120 g (4.23 oz.) •Cable (1ft): 10 g (0.35oz.) •Strain sensing element: 17 g (0.6 oz.) •Easy mounting -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
