Overview
Overview
The WS510-J is an all-in-one weather sensor measuring wind speed, wind direction, air temperature, relative humidity, air pressure, and Class A thermopile solar radiation. A drop-in replacement for the Lufft WS510, the WS510-J reports data every 5 seconds instead of every minute, with upgraded ADC hardware ready for CMP pyranometer integration. Built for bankable, utility-scale Solar PV sites and Meteorological Observation networks, the WS510-J delivers reference-grade Class A thermopile solar radiation for performance and financing requirements, serves as a core Met weather station with flagship-tier radiation built in, and has Class B CMP pyranometer integration. Now you can measure more, maintain less with the WS510-J.
Benefits
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.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.Performance & Tender- Readiness
ISO9060 Class B Pyranometer integrated, IEC 61724-1:2021 Class A compliant 5s output rates on air temperature, relative humidity, air pressure and wind. Integrated design offering WMO compliant wind gust calculation. 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 thermopile radiation sensor and ultrasonic wind sensing, the WS510J 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
