Sensor Technology with Accuracy Beyond Your Imagination

Picture  a new weather sensor, which was so precise that a normal calibration laboratory would not able to measure the accuracy? Imagine there is an environmental sensor, which could serve as the reference for all other environmental sensors. With Lufft’s (Germany) innovative WS3000 this fantasy becomes a reality. The new, high-quality aluminum housing design, the size and especially the performance show off the excellence of this new Lufft product. This makes the innovative weather sensor not only WMO compliant but also attractive for the requirements of airports and meteorological services.

Lufft USA presented the new product sensation at the 96th Annual Meeting of the AMS (American Meteorological Society) in New Orleans, LA, US between January 10 and 14, 2016 for the first time. Before the official product rollout of the WS3000 and WS3100 in the middle of 2016, they will be tested by the several public European weather services for half a year.

The WS3000 measures air temperature, relative humidity and air pressure. It’s the first product version of a new WS1000 series, which will be followed by WS3100 in 2016 and WS4000 in 2017. They will be supplemented with the high precise Kipp & Zonen CMP10 radiation sensor respectively a high-precision radar precipitation sensor.

“The temperature measuring unit consisting of a coiled platinum sensor and a "low-drift electronic" promises a long-term stability of 10mk/a. Also the electronic of the air pressure measurement is very stable in the long term with 0,05hPa/20a. The heated humidity sensor responses extraordinary fast and without any saturation effect. It supports a 1-point, 2-point and multipoint calibration for each sensor. If desired, a second, redundant pressure sensor can be added. For the built-in fan, we calculate with a life cycle of 180.000h, which equals 20 years. Moreover, the anodized aluminum housing with the stainless steel mounting holders, the sensor is very robust and contrasts with the other WS family members by design and accuracy. All single parts are fixed with standard Allen screws and can be deployed easily for installation, maintenance and calibration purposes”, explains head of Lufft development Axel Schmitz-Hübsch.

The whole new WS1000-series communicates via RS485 and WIFI interface, which can be de-activated on request. The main advantage of a WIFI interface is the opportunity to view the sensor’s data and to configure it via laptop, mobile phone or tablet comfortably. Alternatively users can receive the data via the UMB-Binary, UMB-ASCII, SDI-12, MODBUS and NMEA protocol.
