摘要
介绍一种测定气体流速的仪表,它的传感器由2个热敏电阻器组成:一个常温状态下的热敏电阻器测环境温度;另一个实际被加热的热敏电阻器测气体的流速。这台仪表采用了PWM(脉宽调制)、线性化、温度补偿和有关的单片机数字技术。
A anemometer for measurements of the air flow is introduced. The probe of this meter consists of two thermistors. There are PWM (Pulse-width modulation), linearization,temperature compensation and one-chip microcomputer techniques in it.
