概述
The CHECK-LINE CDT-2000HD Combination Portable Tachometer combines the best features of both contact and non-contact models to accurately measure RPM, surface speed and length.
When using the non-contact mode, rotational speed (RPM) is measured using a visible beam of light. The CDT-2000HD can be up to 24 inches away from the small piece of reflective tape that is affixed to the rotating element. In the contact operating mode, the speed is sensed by directly contacting rotating device using one of the contact adapters supplied with the instrument.
离心式转速仪
离心式转速仪利用离心力与拉力的平衡来指示转速。 离心式转速仪是最传统的转速测量工具，是利用离心力原理的机械式转速仪；测量精度一般在1~2级，一般就地安装。一只优良的离心式转速仪不但有准确直观的特点，还具备可靠耐用的优点。但是结构比较复杂 。
磁性转速仪
磁性转速仪利用旋转磁场，在金属罩帽上产生旋转力，利用旋转力与游丝力的平衡来指示转速。 磁性转速表，是成功利用磁力的一个典范，是利用磁力原理的机械式转速仪；一般就地安装，用软轴可以短距离异地安装。磁性转速仪，因结构较简单。异地安装时软轴易损坏。
The CDT-2000HD's rugged construction, portability and outstanding features make It an ideal choice for maintenance personnel, machine operators or others in a wide variety of machinery and material handling applications.
A non-contact only version, the CDT-1000HD
转速表一般设置在仪表板内，与车速里程表对称地放置在一起。转速表是按照磁性原理工作的，它接收点火线圈中初级电流中断时产生的脉冲信号，并将此信号转换为可显示的转速值。发动机转速越快，点火线圈产生的脉冲次数越多，表上显示的转速值就越大。
轿车一般都是电子式转速表，有指针式和液晶数字显示式，表内有数字集成电路，它将点火线圈输送过来的电压脉冲经过计算后驱动指针移动或数字显示。另外还有一种转速表是从发电机取出脉冲信号送到转速表电路解释后显示转速值，不过因受发电机皮带打滑等因素影响，数值不太精确。
