Campbell Scientific WXT520 Transmitter Specification

The Campbell Scientific WXT520 is a compact, all-in-one weather transmitter designed for efficient and reliable meteorological monitoring. It integrates multiple sensors to measure key weather parameters, including wind speed and direction, precipitation, barometric pressure, temperature, and relative humidity. The wind measurements are obtained using an ultrasonic anemometer, which offers accurate and maintenance-free operation without moving parts. Precipitation is detected through a capacitive sensor that measures both cumulative rainfall and individual rain events, enhancing data reliability.

The WXT520 employs a capacitive barometer for pressure measurements, ensuring precision across a wide range of environmental conditions. For temperature and humidity, the device uses a capacitive sensor that provides stable and accurate readings. The transmitter communicates data via an RS-232 or RS-485 serial interface, allowing for easy integration with data loggers or other systems. It supports various communication protocols, including SDI-12, making it versatile for different applications.

Designed for durability, the WXT520 is housed in a robust, UV-stabilized plastic enclosure that withstands harsh weather conditions. It operates efficiently in temperatures ranging from -52°C to +60°C, making it suitable for diverse climates. The device is lightweight and easy to install, reducing deployment time and maintenance efforts. With its low power consumption, the WXT520 is ideal for remote installations where power resources are limited.

Overall, the Campbell Scientific WXT520 Transmitter offers a comprehensive solution for accurate weather monitoring, combining multiple sensor technologies in a single unit to deliver reliable data for meteorological, agricultural, and environmental applications.

Campbell Scientific WXT520 Transmitter F.A.Q.

How do I properly install the Campbell Scientific WXT520 Transmitter?

To install the WXT520 Transmitter, mount the device on a mast or mounting pole using the provided mounting kit. Ensure the unit is level and secure, and connect the necessary cables for power and data transmission. Refer to the installation manual for specific wiring instructions.

What are the common troubleshooting steps if the WXT520 is not powering on?

First, check the power supply to ensure it is delivering the correct voltage. Verify all connections are secure and inspect cables for damage. If the issue persists, consult the user manual for further diagnostics or contact technical support.

How can I calibrate the sensors on the WXT520 Transmitter?

The WXT520 sensors are factory calibrated and typically do not require user calibration. However, if necessary, refer to the manual for instructions on accessing the calibration mode and making adjustments using the configuration software.

What is the best way to maintain the WXT520 for optimal performance?

Regular maintenance includes cleaning the sensor surfaces, checking for physical damage, and ensuring all electrical connections are secure. Perform a visual inspection monthly and a detailed inspection annually.

How do I update the firmware on the WXT520 Transmitter?

To update the firmware, download the latest version from the Campbell Scientific website. Connect the WXT520 to a computer using the appropriate interface, and follow the instructions provided with the firmware file to complete the update process.

Can the WXT520 measure snowfall and how accurate is it?

The WXT520 is designed to measure various weather parameters but it does not directly measure snowfall. It measures precipitation as liquid equivalent, which may not accurately represent snowfall unless converted using additional calculations or equipment.

How do I interpret the data output from the WXT520?

The WXT520 outputs data in a format specified in the user manual, typically using standard meteorological data units. Use Campbell Scientific software or compatible third-party applications to parse and visualize the data for analysis.

What environmental conditions can the WXT520 withstand?

The WXT520 is designed to operate in harsh weather conditions, with a temperature range of -52°C to +60°C and protection against dust and water ingress (IP66). However, ensure it is installed according to the guidelines to maximize durability.

How can I connect the WXT520 to a data logger?

Connect the WXT520 to a compatible data logger using the appropriate communication protocol (RS-232, RS-485, or SDI-12) as detailed in the installation guide. Configure the data logger to recognize the WXT520 for data collection.

What should I do if the WXT520 is not providing accurate readings?

First, check the sensor and housing for any obstructions or damage. Ensure the device is properly calibrated and installed in an ideal location free from interference. If the problem persists, consult the troubleshooting section of the manual or contact support.
