Wireless Analog Gauge Reader

AGR-100

Category: Sensors

E4A’s Analog Gauge Reader represents a new generation of industrial sensing technology, delivering autonomous analog gauge monitoring through Bluetooth® 5.0 connectivity, advanced edge AI, and a sophisticated live feed + AI-enabled provisioning/calibration interface. Using an integrated camera system, the AGR-100 accurately interprets and analyzes multiple gauge readings from a single device, enabling fast, reliable, and cost-effective deployment across demanding industrial environments.

The intuitive live feed interface simplifies setup, remote calibration, and device provisioning, reducing commissioning time while improving operational accuracy. Edge AI processing ensures dependable performance with real-time visual analysis and enhanced data reliability in dynamic field conditions. Powered by E4A’s rechargeable BP-100R battery pack, the AGR-100 is engineered for uninterrupted, long-term operation with minimal maintenance.
