7、6-1994船舶气象仪检定规程本规程适用于新制造、使用中和修理后的旋桨式和风杯式船舶气象仪(以下简称气象仪)的检定。一概述气象仪用于各类船舶进行风速、风向、温度、湿度等气象要素观测。它主要由传感器、显示器及电缆等部分组成。二技术要求气象仪的基本性能参数应符合下列要求:风速、风向、湿度、干、湿球温度传感器的测量范围和允许误差应符合表1要求。项目测量范围允许误差风速(m/s)1.5一60士(0.5+0.05x实际风速)风向(。)0一360旋桨式为士5，风杯式为18干球温度/℃一30一+45士0.5湿球温度/℃

8、0一+45士0.5湿度10%一100%士6%1.2起动风速不大于1.2m/s.1.3当风速为1.2m/s时，机身尾翼(或风向杯)不感应角应不超过110001.4配对使用的干、湿球温度传感器在测量同一状态的温度时，两者示值之差不大于0.3℃。2气象仪传感器应符合下列要求:2.1每个旋桨(或风杯)的形状和尺寸应相同，相邻两臂间的夹角应相等，转动平面与机身(或感应轴)的轴线应相互垂直。2.2旋桨(或风杯)应能随遇平衡，转动灵活平稳，
