数字质量流量传感器
以0-300 SLPM的速度输出空气和氧气的流量,精度为读数的2%,并提供2毫秒的流量采样响应时间。 内部微处理器测量来自内部热敏电阻和热线风速计的信号,以线性化流量测量,并允许对流量和温度输出读数进行多种设置。 小型化,轻巧的设计非常适合OEM应用,尤其是医疗,半导体和气体分析仪产品。
产品特色
数字质量流量计
与大多数流量计不同,数字质量流量计具有触摸屏界面,可在几秒钟内立即更改显示内容。 这种更改包括为每个规范选择显示测量单位,包括许多科学和工程应用中典型的标准单位。 对于测量空气和氧气的混合物,氧气的百分比是可调节的。 与大多数流量计不同,数字质量流量计由于背压高达100 psig,可以自动调整流量计算中的典型误差。 流量计还具有可选的0-5伏特输出作为流量的信号输出方式,可根据用户喜好调节采样率,用于示波器或电压表。
