Cảm biến thời tiết đo tầm nhìn Campbell Scientific CS125
The 52202, manufactured by R. M. Young, is a thermostat-controlled, electrically heated, tipping bucket rain gage. You can use it to measure rain, snow, and other frozen precipitation. Its catchment area of 200 cm2 and measurement resolution of 0.1 mm meet the recommendations of the WMO. This heated rain gage is compatible with most Campbell Scientific data loggers, and it is used in environmental monitoring applications.
Benefits and Features
- High precision—tips at 0.1-mm increments
- Heating element melts snow and ice for year-round measurements
- Compatible with many Campbell Scientific data loggers
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 data logger pulse count channel.
The 52202 has a thermostat-controlled internal heater that melts snow or other frozen precipitation. This heater requires a reliable source of 24 Vac power. A wall transformer is shipped with the 52202 that plugs into a wall socket to provide the required 24 Vac power.
