Wireless Data Acquisition Unit

Overview

The Enviko CET-20L-CAT1 is a multi-channel intelligent data acquisition unit for structural health and engineering safety monitoring at remote sites. It reads vibrating wire, resistance, voltage, current, thermocouple and RS485 sensors on up to 64 channels, sends data over a CAT1 (4G LTE Category 1) wireless link, and runs on a built-in rechargeable battery with solar charging. With a standby current below 5 μA, it is designed for long-term unattended monitoring of bridges, slopes, tunnels, dams and other infrastructure.

Key Features

• Multi-sensor compatibility: vibrating wire, resistance, voltage, current, thermocouple and RS485 sensors
• Flexible channel configuration: 8, 16, 32, 48 or 64 channels
• CAT1 (4G LTE) wireless communication for remote automated monitoring and distributed field deployment
• Ultra-low power: standby current below 5 μA, for rechargeable battery and solar-powered operation
• Automatic data recovery: data is stored locally during communication interruptions and retransmitted automatically once the network is restored
• Local and remote parameter configuration
• Wide operating temperature range: −30 °C to +80 °C

Applications

• Bridge structural health monitoring
• Slope and landslide monitoring
• Tunnel and dam safety monitoring
• Long-term unattended sites without mains power or wired networks
• Distributed monitoring points across large infrastructure projects
