    • This invention is directed to a combination touchless (photo type) and contact type tachometer having a digital display for measuring high, medium and low rotating and surface speeds. Mechanical rotation may be detected by a photo emitting-receiving sensor on the left-hand end of the device or by the contact transmitter located on the right-hand side. The received signal is amplified by an amplifier circuit and regulated by a regulator circuit. Subsequently the data is processed by a standard micro-processor IC circuit, for performing calculations, unit conversion and display decoding. The speed and other information are precisely displayed by a shiftable and reversible, rotatable 180.degree., digital displaying unit to achieve the advantages of an easy to read, precise, economical and effective tachometer.
    • 本发明涉及一种具有用于测量高,中,低转速和表面速度的数字显示器的无接触(光型)和接触式转速计。 机械旋转可以通过位于设备左侧的光发射接收传感器或位于右侧的接触式发射器来检测。 接收信号由放大器电路放大并由调节器电路调节。 随后,数据由标准微处理器IC电路处理,用于执行计算,单位转换和显示解码。 速度和其他信息通过可移动和可逆的180°数字显示单元精确显示,实现了易于阅读,精确,经济和有效的转速计的优点。
