概述
转速计，又名转速表、转速仪，是机械行业必备的仪器之一，用来测定电机的转速、线速度或频率。常用于电机、电扇、造纸、塑料、化纤、纺织、汽车、飞机、轮船等制造业。 大多常用的为手持离心式转速计。美国Checkline旗下的转速计一般为数字式，有接触式和非接触式两种测量。非接触式采用光电器件测量，无连接轴，对被测件无任何影响，提高测量精度。 例如Checkline DT-105A/DT-107A型是一款手持接触式转速计，自带周长为12英寸的主轮，使得表面速度测量更加安全简单。 Checkline DT-105A (LCD MODEL) Checkline DT-107A (LED MODEL) Check-line DT-105A-12 (LCD MODEL with 12" Circumference Wheel) Check-line DT-107A-12 (LED MODEL with 12" Circumference Wheel) Accurately measure rotational and surface speed, as well as length. Built-in selector switch permits the user to display readings in a wide variety of engineering units. The Check-Line DT-105/7A-12 includes a 12" circumference measuring wheel which is offered for safer and easier surface speed measurement by keeping the users hand farther from the moving surface and slowing down the rotational speed.
