CET-04/08 Wireless Dynamic Signal Acquisition Unit
Short Description:
The CET-04/08 is a low-power, high-precision wireless dynamic data acquisition unit designed for bridge structural health monitoring and dynamic response measurement.
It supports strain, voltage, current, and IEPE sensor inputs, provides high-speed 24-bit data acquisition, and uploads monitoring data through 4G wireless communication. The monitoring cycle can be remotely configured according to project requirements, making it suitable for long-term unattended bridge monitoring.
Key Features
- 4 / 8-Channel Acquisition: Flexible configuration for different monitoring requirements.
- 24-bit High-Precision ADC: Dynamic range over 106 dB for accurate signal acquisition.
- High-Speed Sampling: Up to 200 kHz per channel, with a maximum total sampling rate of 1 MHz.
- Multiple Signal Inputs: Supports strain, voltage, current, and IEPE sensors.
- 4G Wireless Communication: Enables remote monitoring and data transmission without wired network infrastructure.
- Remote Monitoring Cycle Configuration: Acquisition cycles can be remotely adjusted according to monitoring requirements.
- Low-Power Design: Automatically enters standby mode between acquisition cycles.
- Solar Power Support: Suitable for long-term unattended field monitoring.
- Expandable Design: Channel capacity can be expanded through cascading.
- Easy Field Deployment: Compact design for distributed monitoring locations.
