\rYF6-80<\/span><\/strong>型风速报警仪简介<\/span><\/strong>:<\/span><\/strong>
\rYF6-80<\/span><\/strong><\/span><\/strong>型风速报警仪<\/span><\/strong>,<\/span><\/strong>可测<\/span><\/strong>0~80m/s<\/span><\/strong>，功能同<\/span><\/strong>YF6-2<\/span><\/strong>型，测风速的范围扩大。<\/span><\/strong>
\r<\/span><\/strong>1<\/span><\/strong>、测风范围<\/span><\/strong>：<\/span>0<\/span>～<\/span>60m/s<\/span>，误差为<\/span>±(0.5+0.05*V)m/s,V-<\/span>风速测量值<\/span>
\r2<\/strong><\/span>、风速显示<\/strong>：显示<\/span>1<\/span>～<\/span>10<\/span>秒内任意设置的风速采样时间的采样一次的平均风速最小显示值为<\/span>0.1m/s<\/span>，风速显示可以<\/span>m/s<\/span>与风级切换<\/span>.
\r3<\/strong><\/span>、预警报范围<\/strong>：<\/span>1<\/span>～<\/span>60m/s<\/span>，任意设置<\/span>
\r4<\/strong><\/span>、警报范围<\/strong>：<\/span>1<\/span>～<\/span>60m/s<\/span>，任意设置<\/span>
\r5<\/strong><\/span>、模拟量输出<\/strong>：<\/span>4<\/span>～<\/span>20mA<\/span>对应<\/span>0<\/span>～<\/span>60m/s<\/span>（也可注明<\/span>0<\/span>～<\/span>20mA<\/span>或电压模拟量输出）<\/span>
\r6<\/strong><\/span>、电源：<\/strong>交流<\/span>220V<\/span>～<\/span>240V 50Hz<\/span>或<\/span>60Hz<\/span>（也可注明需要其他规格或直流电源）<\/span>
\r7<\/strong><\/span>、遥测距离<\/strong>：<\/span>300<\/span>米（三芯屏蔽电缆线截面积<\/span>0.4mm2<\/span>）<\/span>
\r8<\/strong><\/span>、体积<\/strong>：传感器高<\/span>250mm<\/span>，风杯旋转直径<\/span>Φ184mm 
\r9<\/strong><\/span>、重量<\/strong>：约<\/span>2kg 
\r10<\/strong><\/span>、原理与功能：<\/strong>
\r<\/span><\/strong>（<\/strong>1<\/span><\/strong>）、<\/strong>风力作用于风杯带动光电码盘，风速脉；中连续送进主机的单片微机计数电路，先进行一秒钟采样，后进行<\/span>1<\/span>～<\/span>10<\/span>秒钟内任意设置的连续的算术平均数送数码管显示平均风速值，同时输出电压、电流模拟量。当平均风速值与选择的风速值比较达到预警报值时，绿灯显示；达到警报值时则红灯显示同时警报发生器发出持续的鸣叫。<\/span>
\r<\/span>（<\/strong>2<\/span><\/strong>）、<\/strong>主机有预警报、警报二副触点，每一副触点中间为中线，左边为常开，右边为常闭，当风速值达到预警报值或警报值时：继电器工作，常闭触点放开，常开触点吸合，用户可按需要使用其功能：另有电流模拟量<\/span>4<\/span>～<\/span>20mA<\/span>输出触点，供数据采集使用<\/span>.<\/span>\r<\/p>\r
