1. Product Overview
Click here to download the datasheet.
The BT8800S self-capacitive/BT8800SPRO plug-in tide gauge is a battery-powered water-level monitoring instrument that records water depth (pressure) and temperature for extended periods.
It includes water level and temperature sensors, built-in large-capacity FLASH memory, and a high-capacity, long-life lithium battery; the battery is easy to replace, making it suitable for water level and water temperature measurement in surface water, groundwater, and marine environments.
2. Features
- BT8800SPRO plug-in: dual-mode operation; self-capacitive/online mode can be switched to adapt to different application occasions (BT8800Sonly self-capacitive mode)
- Easy to replace the battery;
- Minimum acquisition interval 1S;
- High stability: using high-quality and high-stability pressure sensing elements
- High accuracy: water level accuracy 0.05%F.S, resolution 1mm; temperature accuracy ±0.2°, resolution 0.1℃;
- Multi-function: internal built-in battery and 128M memory, can collect and store data regularly;
- Full Parameters: water level, temperature, water pressure, time and other factors are monitored and recorded simultaneously;
- Signal standard: RS485; data is exported in a special format for the host computer software;
- Protection level: IP68 protection;
- Temperature compensation: full-range digital calibration, full-temperature zone temperature error compensation;
- Sensor electrical characteristics: over-voltage protection, surge voltage protection and power supply polarity reverse connection protection to avoid electrical damage caused by operating errors;
- This model is an absolute pressure product, and can be equipped with an atmospheric pressure gauge of the same model as atmospheric pressure compensation, which will increase the system accuracy.
