52202 Electrically Heated Rain and Snow Gage 1. General Description RM Young's Model 52202-L is an electrically heated precipitation gage that provides year-round measurement of rain or snow. This gage requires a reliable source of 24 Vac power. It includes a wall transformer that plugs into a wall socket and provides 24 Vac. Output is a switch closure for each bucket tip. A -L after the model number indicates that the cable length is specified when ordering. Throughout this manual, the rain gage will be referred to as the 52202. The 260-953 Alter-Type Wind Screen can be used with the 52202 to minimize the effect of strong winds on the 52202's measurements. 2. Specifications Sensor Type: Tipping bucket with magnetic reed switch Accuracy: 2% up to 1 in. h-1 (25 mm h-1); 3% up to 2 in. h-1 (50 mm h-1) Resolution: 0.004 in. (0.1 mm) Orifice Diameter: 6.3 in. (16 cm) Catchment Area: 31 in.2 (200 cm2) Temperature Range: -20° to +50°C Humidity Range: 0 to 100% Power: 18 Watts @ 24 Vac Contact Rating: 24 Vac/dc, 500 mA maximum Dimensions Diameter: 7.3 in (18.5 cm) Height: 11.8 in. (30 cm) NOTE The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings. 1
