Heated rain gauge TRwS

200 cm²400 cm²500 cm²

Robust precipitation sensor based on weighting principle High measurement accuracy for all types of precipitation (drizzle, heavy rain, sleet, snow etc.) Heating ring to prevent ice formation or snow caps WMO-Compliant Windscreen for exposed locations (optional) Precise: The TRwS uses a precision scale to measure liquid and solid precipitation with a relative accuracy of ± 1%. Precipitation is directed via a defined collection area (200 cm², 400 cm², or 500 cm², depending on the type) into a collection container located directly on the scale. Low maintenance requirements: Unlike conventional precipitation gauges, the TRwS does not require the customary maintenance trips for cleaning of the hoppers and the collecting filter. The set of integrated precision scales is factory calibrated, it is drift-free and requires no adjustment. Expandability: An adjustable pulse output and an SDI-12 output are available as communication interfaces. For storage of the measured values ​​of rainfall volume and intensity, the use of the compact, battery-powered SEBA data collector - Unilog-Light-R - is recommended. When combining the TRW 200 with the GSM742 radio modem, data transmission or being alerted to any problem (i.e. excessive precipitation) via alarm signal becomes possible.
