Introduction
Nokeval provides solutions for integrating Vaisala Weather Transmitters with PromoLog data acquisition software. This setup allows users to view and record various weather parameters efficiently.

Specifications
The system requires a connection between the Vaisala WXT Series weather transmitters and a computer via a serial bus. This is facilitated by the Nokeval DCS770 USB-RS485 serial bus converter. The weather transmitters, such as the WXT520, are designed for applications needing stable and cost-effective wind measurements. They measure wind speed, direction, liquid precipitation, barometric pressure, temperature, and relative humidity.

Procedures
To utilize the system, the WXT sensor must be connected to a computer using the specified converter. PromoLog software can then be used to create customized displays and visualizations of the weather data. Data can be recorded at specified intervals for analysis.

Advanced Features
PromoLog offers advanced functionalities such as SMS alarms and can output weather parameters as analogue signals using the Nokeval 7470 Output Unit.

Requirements
A PromoLog Server-32 license is necessary to run the data acquisition software on a PC. The system also requires a 24 VDC power supply for the WXT520 weather multi-sensor.

Conclusion
This setup provides a comprehensive solution for monitoring essential weather parameters using Vaisala transmitters and Nokeval's data acquisition tools.
