讨论一个三线制PT100电阻桥的接法
PT100是很常用的热电阻,精度比较高,温度范围比较宽(-200-800℃),应用的时候最简单的是两线制,用恒流源加电流直接测电压,算电阻,再转换成温度。当引线较长时,引线的电阻便不能忽略,于是就有三线制接法和四线制接法,来消除引线电阻的影响。三线制由于性价比较高(比四线制少一根线,比两线制精度高),因此应用比较普遍,一般的接法是做一个电阻桥。在网上找三线PT100接线方法的时候找了两种,感觉都有问题,拿出来大家共同分析一下:引线电阻接入到两个两个桥臂的分压电阻上。另外一根线接基准电源。...

直流电和交流电的定义
在我们段码液晶屏的定制行业,大家都知道液晶屏的供电方式是交流电,而背光的供电方式是直流电,他们虽然是在同一个PCB板子带上的配套使用,但是供电方式确不一样的,并且很多人不知道什么是直流电什么是交流电。交流电,是指大小和方向随时间作周期性变化的一种电流。交流电是用交流发电机发出的,在发电过程中,多对磁极是按一定的角度均匀分布在一个圆周上,使得发电过程中,各个线圈就切割磁力线,由于具有多对磁极,每对磁极产生的磁力线被切割产生的电压、电流都是按弦规律变化的,所以能够不断的产生稳定的...

MAP传感器介绍
MAP传感器定义:(ManifoldAbsolutePressureSensor)进气压力传感器。进气压力传感器(ManifoldAbsolutePressureSensor),简称MAP。它以真空管连接进气歧管,随着引擎不同的转速负荷,感应进气歧管内的真空变化,再从感知器内部电阻的改变,转换成电压信号,供ECM电脑修正喷油量和点火正时角度。换言之,ECM电脑输出5V电压给进气压力感知器,再由信号端侦测电压值,电脑,当引擎在怠速时,其电压信号约1-1.5V,节汽门全开时,则约有4.5V电压信...

求助大手子给个主意
冲牙器它这里入水管断了。。。。怎么修啊?感觉胶粘不好搞~ 要不要拆开啊?求助大手子给个主意粘不能好使,还是打开吧。。连接处和透明管能拽出来嘛,拽出来再用一些胶水粘一下就好了。直接粘不行,最好拆开换,实在不方便的话,用面粉之类的粉末在待粘接的管子断裂处旁堆成锥形,然后把502滴上去,这比直接粘的强度好得多,至于是否满足要求既看外力的强度,也看你的手艺。 这个想法细致妥帖。。。。。。。。。赞chunyang大哥呀。。。。 chunyang老师,这个方法号...
