mm Precipitation Gauge

0-50 mm Precipitation GaugeThe Model 50202 Precipitation Gauge accurately measures rain or snow precipitation without moving parts. Insulated housings and thermostatically controlled heaters permit operation at temperatures below freezing. Unlike conventional tipping-bucket and weighing gauges the 50202 has no moving parts, making the instrument ideal for use on moving platforms such as buoys and ships. Precipitation measurement is made with a capacitive transducer and electronic circuit that produces a voltage output. Total precipitation can be tracked by a datalogger or recorder.Durable thermoplastic construction with no moving parts offers excellent corrosion resistance and long term reliability. Insulated housings and thermostatically controlled heaters permit operation at temperatures below freezing. Unique design with centrally located capacitive sensor is unaffected by unsteady conditions: making the instrument ideal for use on moving platforms such as buoys and ships. For extra security in extreme conditions, Model 50222, Heavy Duty Mounting Bracket is recommended.Rain or snow collected in the catchment funnel is directed into the measuring chamber; 1mm of precipitation produces a 5mm rise in the chamber. Column level is sensed by a capacitive probe and converted to a linear voltage signal that can be read by external electronics. When the column level reaches a maximum of 250mm (50mm of precipitation), the chamber automatically empties and the process repeats. Total precipitation can be tracked by a datalogger or recorderModel 50203 is unheated.This product has been tested and shown to comply with European CE requirements for the EMC Directive (see Declaration of Conformity below). Please note that shielded cable must be used.
