CET2104/2204 Wireless Hybrid Data Acquisition Unit
Short Description:
The CET2104/2204 is a high-performance, low-power wireless data acquisition unit designed for structural health monitoring and engineering safety monitoring.
It combines RS485 digital sensor acquisition with 4-channel analog signal acquisition, supporting vibrating wire, voltage, and current sensors. With remotely configurable acquisition cycles and integrated 4G communication, it is suitable for long-term unattended monitoring of bridges, tunnels, slopes, and geotechnical structures.
Key Features
- Hybrid Digital & Analog Acquisition: Supports both RS485 digital sensors and analog sensors in one unit.
- Up to 64 Digital Channels: Supports 1–64 RS485 digital sensor channels.
- 4 Analog Channels: Supports vibrating wire, voltage, and current signal inputs.
- 4G Wireless Communication: Enables remote data upload to cloud platforms or monitoring servers.
- Remote Configuration: Acquisition intervals can be remotely configured according to monitoring requirements.
- Low-Power Design: Sleep current at the μA level, with average operating current of approximately 100 mA.
- Solar Power Compatible: Suitable for long-term field deployment without fixed grid power.
- Vibrating Wire Measurement: Supports 400–5000 Hz vibrating wire sensors.
- High-Resolution Measurement: Frequency resolution 0.1 Hz and temperature resolution 0.1°C.
- Suitable for Outdoor Monitoring: Designed for distributed and unattended structural monitoring applications.
