Overview

The 52202-20-L is a stainless steel electrically-heated tipping bucket rain gauge that measures rain, snow, and other frozen precipitation. Its catchment area of 200 cm2 and measurement resolution of 0.1 mm meet the recommendations of the World Meteorological Organization. This heated rain gauge is compatible with all Campbell Scientific dataloggers, and is used in environmental monitoring applications. The 52202-20-L is meant to be used in environments where corrosion is a concern (i.e. marine environments).

Detailed Description

The 52202  funnels precipitation into a bucket mechanism that tips when filled to the calibrated level. Each tip is marked by a magnetic reed switch closure that is recorded by a Campbell Scientific datalogger pulse count channel.

The 52202 has an internal heater that melts snow or other frozen precipitation. This heater requires a reliable source of 24 Vac power. The C1676 wall transformer is required for use with the 52202, which plugs into a wall socket to provide the required 24 Vac power.
