有客户问我使用皮带速度检测仪是用接触式的好还是非接触式的好？
我的回答是：这个真不一定，主要根据咱那边的使用环境决定的。这两种速度检测器的感知器安装位置

敏度是有些不一样的，速度检测仪开关一般的使用单位，有自己的使用习惯，一开始选择什么样的，会

继续是使用原来选择的款式，速度检测仪这个在使用方面是没有影响的。
DH-S速度检测仪专业皮带机配套产品，速度检测仪带有数字显示，所以也叫做数显式皮带速度检测仪。
我们的这款速度检测仪可以跟什么行业的输送机配套使用呢？冶金、煤炭、矿山、电力，水泥、粮食、

矿山等行业都可以的，用途是非常广泛的。实时显示皮带速度，确保皮带运行安全，可以避免重大人力

财力损失。准确检测、实时显示、耐用性强。


Non-contact Belt Conveyor Speed Tester is control box + sensor head comPOSTTTION of a 

customer asked me to use the belt speed tester is contact or non-contact good? My answer 

is: This really not necessarily, mainly based on our side of the use of environmental 

decision. The sensor installation POSTTTION sensitivity of these two kinds of speed 

detectors is somewhat different. The speed detector switch general use unit, has its own 

usage habits, what kind of first choice, will continue to use the original choice of style, 

speed detector this in the use of the area is not affected. DH-S speed detector 

professional belt machine supporting products, speed detector with digital display, so also 

called digital belt speed detector. Our speed detector can be used with what industry 

conveyor supporting it? Metallurgy, coal, mining, power, cement, grain, mines and other 

industries can be used for a very wide range of purposes. Real-time display of belt speed 

to ensure belt operation safety, can avoid significant human and financial losses. Accurate 

detection, real-time display, strong durability.

下面就让我来带领大家了解这款DH-S速度检测仪：
工作原理：速度检测仪传感头把所检测的带速变成脉冲信号，送入89C51单片机在单位时间内计数，然后

同预置的带速相比较，做出大于、等于或小于的判断，速度检测仪使对应的控制继电器吸合当被监测的

运输皮带的运行速度低于（高于）预先设定值时，它能发出报*或停机信号，可有效地避免事故的发生。

速度检测仪可应用于冶金、煤炭、矿山、水泥、电力、粮食等行业的皮带运输机中，速度检测仪是物料

输送系统中实现自动控制所不可缺少的监控装置。

Jining Tiandeli strives to provide a wide range of services to your company with advanced 

technology and excellent product quality. Let me take you to understand this DH-S speed 

detector: Working Principle: Speed Detector Sensor head to detect the belt speed into a 

pulse signal, into the 89C51 single-chip counting in unit time, the velocity detector makes 

the corresponding control relay snap-in when the monitored conveyor belt is running at a 

speed lower than or higher than the preset value, the utility model can send out a report * 

or a stop signal, which can effectively avoid the occurrence of an accident. Velocity 

detector can be used in belt conveyor of metallurgy, coal, mine, cement, electric power, 

grain and so on. Velocity detector is an indispensable monitoring device for automatic 

control in material conveying system.
