52202-L Electrically Heated Rain and Snow Gage

Measure Rain, Snow, and Other Frozen Precipitation
Thermostat-controlled gage

Resumen

The 52202, manufactured by R. M. Young, is an electrically heated tipping bucket rain gage 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 WMO. This heated rain gage is compatible with all Campbell Scientific dataloggers, and it is used in environmental monitoring applications.

Ventajas y características

Alta precisión— vuelcos en incrementos de 0.1mm.
El calentador derrite la nieve y hielo durante todo el año de medición

Descripción detallada

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 is thermostat controlled and 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.

Is the CS700-L, CS700H-L, or 52202-L connected to a control input or a pulse channel?
These rain gages can be connected to either.
- When a control port is used, one lead goes to the 5 V port to provide current, and the other lead goes to a control port to detect the current.
- When a pulse channel is used, one lead goes to the pulse port, and the other lead terminates on a ground terminal.
What can cause a datalogger to not receive correct tipping data?
If data is not being logged correctly, there are two likely causes:
- The reed switch has failed.
- There is a faulty connection from the rain gage to the datalogger, typically caused by a broken conductor or corroded wiring.
What are the indicators that a tipping bucket rain gage has a faulty reed switch?

Not registering any tips, missing tips, or double tips.
What are the indicators that a tipping bucket rain gage is out of calibration?

Not enough tips or too many tips.
What type of wind screen can be used for a tipping bucket rain gage?

The 260-953 Alter-type rain gage wind screen consists of 32 heavy metal leaves that hang freely and swing as the wind moves past them. The swinging leaves act as a wind damper and help minimize the effect of wind on the rain measurements without adding additional turbulence.
What can cause a tipping bucket rain gage to be out of calibration?

When a rain gage is out of calibration, it is usually because of the buildup of dirt and grime on the internal surfaces of the tipping bucket mechanism. Cleaning the internal surfaces usually brings the rain gage back into calibration. It is also possible that a rain gage is out of calibration because it is no longer level.

To minimize the possible occurrence of calibration errors, perform routine cleaning and maintenance of the rain gage at least once every three months. The environmental conditions at a particular site may require a facility to perform cleaning, leveling, and maintenance on a much more frequent schedule.
What are the most common errors with a tipping bucket rain gage?

The most common errors are either that the rain gage appears to have drifted out of calibration or that the tips are not being correctly recorded by the datalogger.

Mounting

The 52202 is shipped with a mounting pipe. The rain gage clamps onto this pipe, which is then fastened to a crossarm using the CM220 Right-Angle Mounting Kit, or mounted onto the top of a tripod using the CM216 Sensor Mounting Kit.

Wind Screen

Campbell Scientific offers the 260-953 Wind Screen to help minimize the affect of wind on the rain measurements. This wind screen consists of 32 leaves that hang freely and swing as the wind moves past them.
