RAINFALL SENSOR 3864, Tipping Bucket (With Heating 3864H) A Rain-o-matic® water precipitation sensor adapted for use with Aanderaa Field Monitoring Equipment Monitoring rainfall is of great interest to meteorologists and climatologists as well as to the general public. The tipping bucket type Rainfall Sensor 3864 is designed to measure this important parameter with great accuracy and reliability. It is a lightweight, frostproof, heat-resistant and rugged sensor specially adapted for use with the Aanderaa Automatic Weather Station 2700. The sensor has passed the so called Arizona test and can be used under almost any climatological condition. The sensor housng is i made of outdoor polystyrene called STYROSUN. The collecting funnel has an orifice area of 200 cm2. Rainfall is collected in the funnel and led into a tipping bucket that gives one count for each tipping. Each tipping, which signifies 0,2 mm rainfall, is counted by Pulse Counter 2891. The pulse counter is molded in Polyurethane (Scotchcast for the H model) and connected to a 6-pin output receptacle. The number of pulses in a sampling interval signifies the total rainfall which is measured by the Datalogger 3660 or 3634. The sensor should be mounted on a 50 mm vertical tube. A 1m high Tube with Base Plate, part no. 3285 and an Extension Tube part no. 3776, is available. Using these two items will place the sensor 2m above the ground. Cable 2842 connects the sensor to the monitoring system. A version with heating is designated 3864H. This sensor is delivered with a separate Power Supply 100-230VAC/ 24VDC and the power requirement is maximum 50 watts.
