CET-XZ20 Multi-Channel Data Acquisition Unit
Short Description:
The CET-XZ20 is an intelligent multi-channel data acquisition unit designed for structural health monitoring and engineering safety monitoring. It features a modular design, supports mixed sensor inputs, provides up to 64 physical channels, and supports both wired and wireless data transmission. It is suitable for centralized monitoring applications such as bridges, tunnels, slopes, dams, foundation pits, and other infrastructure.
Key Features
- Multi-Sensor Compatibility: Supports vibrating wire, resistance, voltage, current, thermocouple, and RS485 sensors.
- High-Capacity Data Acquisition: Available with 16 / 32 / 64 channels, with up to 64 physical channels per unit.
- Wired & Wireless Communication: Supports LAN, Internet, GPRS, and CDMA communication.
- Automatic Data Recovery: Data is stored locally during communication interruptions and automatically retransmitted once the network is restored.
- Ultra-Low Power Consumption: Standby current approximately 5 μA.
- Remote Configuration: Supports both local and remote parameter configuration.
- Wide Operating Temperature: -30°C to +80°C.
- Industrial Protection: Compact enclosure with IP64 protection for field installation.
