概述

DT-205LR LCD Display with 6" Circumference Measuring Wheel

DT-205LR-12 LCD Display with 12" Circumference Measuring Wheel

DT-207LR LED Display with 6" Circumference Measuring Wheel

DT-207LR-12 LED Display with 12" Circumference Measuring Wheel

The DT-205LR & DT-207LR combine the best features found in both contact and non-contact tachometers for the accurate measurement of rpm, surface speed and length. The screw-in contact adapter makes it quick & easy to convert from non-contact to contact operation.

由于是指针指示符合传统视认习惯，又便于计算机远程处理和网络化要求，所以数字化步进电机仪表是现代汽车仪表和摩托车仪表的发展趋势，Switec公司的步进电机在国内外已广泛用于各种汽车、摩托车和工程机械仪表。车用微型步进电机是一种专用的新型汽车仪表配件，利用它设计的仪表既符合传统视认习惯又能满足数化处理要求，是现代化仪表的理想配件

转速是旋转体转数与时间之比的物理量，工程上通常表示为转速=旋转次数/时间，是描述物体旋转运动的一个重要参数。电工中常需要测量电机及其拖动设备的转速，使用的就是便携式转速表。转速表是用来测量电机转速和线速度的仪表。转速表种类较多，便携式一般有机械离心式转速表和数字电子式转速表。

参数

转速表将接收的数字脉冲信号（由传感器发出的），处理后直接读入cpu的计数口，经软件计算出转速、和指针相应的位置，再通过cpu的控制口，放大后驱动步进电机正负方向旋转，指示相应转速值（指针直接安装在步进电机的旋转轴上），步进电机走一步仅为1/3度。
