转速计，又名转速表、转速仪，是机械行业的仪器之一，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。
转速计，又名转速表、转速仪，是机械行业的仪器之一，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 YSL-2000HD型是一款接触式&非接触式转速计，精准测量转速，速度，表面速度和长度。适用于纱线，细丝，轴，电机，轮滑，传送带，造纸网和织物网。
The CHECK-LINE YSL-2000HD combines the functions of three separate instruments in one, easy-to-use device.
It accurately measures the speed and length of yarns, and other filaments using a unique "wrapper" roller. This precision roller directs the filament onto the low-inertia, U-grooved measuring wheel to maximize contact and eliminate filament slip and breakage.
The Check-line YSL-2000HD can also be used as either a contact or non-contact tachometer to measure rotational speeds of shafts, motors, pulleys, etc. or linear speeds of moving surfaces such as conveyor belts, webs of paper or fabric, etc.
Slide-on measuring heads make it simple to rapidly convert from one function to another
