NOTE: AIRMAR NO LONGER MANUFACTURES THIS PRODUCT
The LB150, Ultrasonic WeatherStation® Instrument meets a growing need for real-time, site-specific, weather information. It is the only ALL-in-ONE weather sensor that calculates apparent wind speed and direction, barometric pressure, air temperature, relative humidity, dew point, and wind chill temperature. With the internal compass and WAAS/EGNOS GPS, true wind speed and direction can also be calculated. Accurate data helps organizations make important decisions regarding weather conditions that affect safety and operations.
Traditional weather instrumentation is composed of several individual sensors including wind cups, which are prone to breaking and are less accurate at low speeds. Airmar’s WeatherStation® Instrument incorporates seven sensors, with no moving parts, all in one compact unit. The UV stabilized, housing is fully waterproof and resistant to chemicals.
The WeatherStation® Instrument comes with our intuitive WeatherCaster™ Software. Data can be viewed in both digital and analog formats and can be saved for a set period of time. The log time can be adjusted in intervals from 6 to 72 hours. Standard NMEA sentences and an RS-422 standard interface allows for the flexibility of designing your own software program to fit your specific application. Our comprehensive technical manual makes the job easy!
Airmar’s WeatherStation® Instrument has a standard 1-14” UNS (3/4” NPT) thread connection to accommodate standard mounting hardware. The waterproof base connector assures trouble-free installation and servicing, while a quick disconnect feature allows for easy removal. Using the standard cable lengths of 10 m or 15 m (33' or 49'), the sensor can be connected to the optional USB Converter. The Converter allows the WeatherStation® Instrument measurements to be displayed on a PC by changing the data from RS-422 standard or NMEA 0183 to USB.
