Overview
The WS700-J is an all-in-one weather sensor measuring wind speed, wind direction, temperature, humidity, pressure, radar-based precipitation, and onboard solar radiation. A drop-in replacement for the Lufft WS700, the WS700-J is built on the same trusted Lufft platform, reporting data every 5 seconds instead of every minute, with live heating-voltage monitoring and self-diagnostics for minimal maintenance. Built for use across applications, the WS700-J is an AWOS-ready weather sensor for aerodrome monitoring, delivers onboard radiation alongside full weather data for solar PV performance-ratio calculations, and is a reference-grade anchor for mixed fleet site monitoring across meteorological sites. Now you can measure more, maintain less with the WS700-J.
Benefits
Reduced Risk, Improved Self-Diagnostics
The WS-J's incorporates improved house-keeping functions, live heating-voltage monitoring, and automatic self-diagnostics to catch a failing component before it corrupts the rest of the instrument and finally your decision-making data set.One Platform Across Networks
The J-Series is a drop-in replacement for legacy WS units, sharing size, weight, mounting, cable connections, available protocol formats and interfaces, and software across the platform. One calibration reference, one spare pool, one standard.Performance & Tender- Readiness
Integrated design offering WMO compliant wind gust calculation and present weather reporting (Synop 4680/wawa). IEC 61724- 1:2021 Class A compliant 5s output rates on air temperature, relative humidity, air pressure and precipitation and wind. Wind speed is reported up to 75 m/s and as our measured parameters 100% tested in our certified calibration process. Each WS-J comes with a FAT certificate.Low Lifecycle Cost by Design
With built-in irradiance, ultrasonic wind and the radar precipitation sensing, the WS700-J has fewer failure points. The new aspirated radiation solution ensures lifetime performance and the single sensor; single cable connection drops total costs of ownership over the full life of your sensor's deployment.Specifications
