SDMS40 Multipoint Schneesensor
Überblick
Der SDMS40 ist kostengünstiger laserbasierter 2D Multipoint-Schneefallsensor. Frühere Laser-Schneesensoren waren kompliziert und teuer, der SDMS40 bietet nun eine moderne Alternative. Performance und Zuverlässigkeit des Sensors wurden gründlich getestet (lesen Sie die Veröffentlichung dazu hier). Der SDMS40 liefert akkurate Daten mit robustem Design zu einem vernünftigen Preis.
Die SDMS wurden in Kanada über drei Winter getestet und hat sich durch Genauigkeit und Robustheit bewährt.
Funktionen und Vorteile
- Detects the onset of snowfall or snowmelt quickly and reliably
- Proven performance by field tests over three winter seasons from 2013 to 2015
- Allows easy installation on poles, building walls, or any structure
- Can be used as an additional gauge to existing weather stations
- Compact and light gauge structure
- Less sensitive to ground conditions
- Filters out noise input caused by obstacles and abnormal situations
- Can operate on natural ground and different types of snow plates
- SDI-12 and RS-232 output

SDMS40 Example Programs v.1 (4 KB) 13-08-2020
Three example CR1000X programs. Two programs use SDI-12 and one program uses RS-232. All example programs read the sensor parameters and perform daily diagnostics. One SDI-12 program includes a constant table to allow the user to change the height and initial snow depth as needed for manual calibration. These programs require SDMS40 firmware v 7.4e or higher.
