Unidata Weather Transmitter
The Weather Transmitter 6501V offers a six-in-one solution to measure barometric pressure, humidity, precipitation, temperature, and wind speed and direction - all with one instrument! Compact and lightweight, the 6501V is suitable for weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels - almost anywhere where real time weather data is needed. Accurate and reliable data provided to you early enough can increase safety to life and property.
To measure wind speed and direction, the 6501V has the Vaisala WINDCAP® sensor that uses ultrasound to determine horizontal wind speed and direction. The array of three equally spaced transducers on a horizontal plane is a Vaisala specific design, which ensures accurate wind measurement from any horizontal wind direction without blind angles and corrupted readings. Barometric pressure, temperature, and humidity measurements are combined in the PTU module using capacitive measurement for each parameter. It is easy to change the module without any contact with the
sensors. Precipitation measurement is based on the Vaisala RAINCAP® sensor.
