转速是旋转物体的转数与时间之比的物理量,是描述各种旋转机械运转技术性能的一个重要参量,是力学动态计量的基础量之一。一切旋转机械的转速均是用转速表、转速测量仪或转速传感器配合二次仪表来实现测量。其中,转速测量仪通常采用微处理器测量控制技术,能够测量转速、周期、频率、计数等多个参数。与转速表相比,转速测量仪测量准确可靠,测量过程和数据处理全部实现自动化,能够直接显示、打印测量结果,或具有通用输出接口以便保存测量结
Rotational speed is the physical quantity of the ratio between the number of rotations and the time of a rotating object. It is an important parameter to describe the technical performance of various rotating machinery operations, and is one of the basic quantities of dynamic measurement of mechanics. All rotating machinery speed is tachometer, speed measuring instrument or speed sensor with the secondary instrument to achieve measurement. Among them, the speed measuring instrument usually uses microprocessor measurement control technology, capable of measuring speed, cycle, frequency, counting and other parameters. Compared with the tachometer, speed measuring instrument accurate and reliable measurement process and data processing are fully automated, can be displayed directly, print the measurement results, or have a common output interface to save the measurement junction
