Web observation system for measuring the axial force of rock bolts that monitor expansion and contraction underground!
The "Battery-Powered Strain Gauge 4ch Web Measurement" can be directly connected to a rock bolt axial force gauge on-site, allowing immediate initiation of web observation. It operates for one year on built-in batteries with ultra-low power consumption, making it a hassle-free observation system. The signals from four rock bolt axial force gauges installed on-site are connected to the observation system. The observation system supplies 5V to the bridge only during measurement, directly measuring the output voltage with a high-precision AD in μV. The measurement results are compiled and regularly sent to the server via email. 【Features】 ■ Compact size: 29.5 cm high x 15.5 cm wide x 12.5 cm thick, fits in hand ■ Lightweight at 1.75 kg, including eight built-in batteries ■ Houses all components: batteries, measurement equipment, and FOMA modem, completing web observation with just this unit ■ Stored in an IP65 waterproof case and easily mounted with construction pipe mounting hardware ■ Operates for one year on eight AA batteries, measuring every 10 minutes and updating the web every 6 hours *For more details, please download the PDF or feel free to contact us.
