This precipitation sensor concerns an extremely precise rain gauge with pulse output as encoder for data collection systems and remote data transmission. The precipitation volume is detected by a plastic tipping bucket supported by ball bearings with spirit level and adjustment screw. It is also available with a collecting surface of 400 m² if required for the respective task. The RG 50 can furthermore also be equipped with a bird protection ring and with a heater if used in areas at risk from frost. The housing made of painted aluminium is weatherproof and tough.
