美国R.M.Young 50202型雨量计是一款先进的降水测量仪器，能够精确测量雨或雪的降水量。它采用独特的无移动部件设计，与传统的翻斗式和称重式雨量计不同，这种设计使其在移动平台上（如浮标和船舶）使用时更加稳定。该雨量计的外壳具有良好的绝缘性，并配备了恒温控制加热器，能够在低于冰点的温度下正常运行。其测量原理是利用电容传感器和电子电路产生电压输出，总降水量可通过数据记录器或记录器进行跟踪。该雨量计的测量范围为0至50毫米，精度为±1毫米。其工作温度范围为-20至+50°C，能够适应多种气候条件。此外，该雨量计的尺寸为高度65厘米，直径14厘米，集水区直径为133毫米。它通过U型螺栓安装在直径为25-50毫米的垂直管上，重量为2.5公斤。

The R.M.Young 50202 precipitation gauge is an advanced instrument for measuring rain or snowfall. It features a unique design without moving parts, unlike traditional tipping-bucket and weighing gauges. This design makes it particularly stable for use on moving platforms such as buoys and ships. The gauge has an insulated housing and a thermostatically controlled heater, allowing it to operate at temperatures below freezing. It measures precipitation using a capacitive sensor and electronic circuit to produce a voltage output, with total precipitation being trackable via a datalogger or recorder. The measurement range is 0 to 50 mm with an accuracy of ±1 mm. It operates within a temperature range of -20 to +50°C, making it suitable for various climates. The gauge is 65 cm in height, 14 cm in diameter, and has a catchment diameter of 133 mm. It is mounted on a vertical pipe with a diameter of 25-50 mm using U-bolts and weighs 2.5 kg.
