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。 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 DLM-107型转速计/测长仪，主要是用来测织物和运输带的长度。 The Model Check-line DLM-107 Digital Length Meter is designed to accurately measure fabric length (or other moving belt material), in feet or meters.
