    什么是风速仪?

    风速仪也被称为风速计,是一种测量空气流速的仪器。

    风速仪的优势特点

    风速仪可以准确地监测风速,并以各种方式为测量提供数据。风速仪有多种类型,每种风速仪的功能各不相同,具体取决于其类型和所使用的测风应用类型。大多数手持式风速监测器坚固耐用,可以承受可能出现的各种因素,并且具有防风雨性,尤其是那些可以安装以进行长时间测量的风速监测器。它们用于从天气预报到高科技科学研究实验室的各种应用。

    风速仪的类型

    风速仪的类型取决于它所使用的测量应用类型,常见的类型如下:

    • 风杯式风速仪:是由三个互成120°的拋物面或半圆形的空杯构成一个平面的测风仪器,根据风杯对风响应的转动速度曲线就可以测量风速的大小。
    • 旋叶风速仪:它也被称为螺旋桨叶片风速仪,使用旋转的风叶而不是杯。一些手持式旋叶风速仪被称为叶轮式风速仪,它们的螺旋桨叶片有笼罩装置保护,可以保护您的手。
    • 热线风速仪或热敏式风速仪:常用手持使用,通过将细线加热到特定温度,然后测量线被气流冷却的速度来计算风吹的速度。
    • 压力管风速仪:这种风速仪使用风产生的压力来测量其速度。
    • 带速度或温度曲线的热线风速仪:它们通常用于风洞中的电路板和散热器分析。
    • 超声波风速仪:专业的风速仪是使用高频声音来测量风速。其内置的电路能测量声音从每个发射器传到相应接收器所需的时间。它的电路能测量光束速度的差异,并使用它来计算风吹的速度。

    风速仪的应用范围

    风速仪是在各种应用中进行测试和测量的关键仪器,其应用范围如下:

    • 天气爱好者和业余玩家
    • 暖通空调安装维修人员
    • 环境测量的科学家
    • 农业:在作物喷洒前需检查风向或风速等条件
