一、什么是電子電位器
電(dian)子電(dian)位(wei)器(qi)也被稱(cheng)為數字電(dian)位(wei)器(qi)。它是一種頗具發(fa)展前(qian)景的(de)新型電(dian)子器(qi)件,在(zai)許多領域可取(qu)代(dai)傳統的(de)機械電(dian)位(wei)器(qi)。其優點為:調(diao)節精度高;無(wu)噪聲,工作壽命極(ji)長;無(wu)機械磨損(sun);數據(ju)可讀寫;具有配置寄存(cun)(cun)器(qi)及數據(ju)寄存(cun)(cun)器(qi);多電(dian)平量存(cun)(cun)儲(chu)功(gong)能。
電子電位器具(ju)有以(yi)下(xia)幾點(dian)特性:
1、采用傳感(gan)器(qi)原理生產,具有良好的線性、精度和溫(wen)度穩定性。
2、采用(yong)軟件(jian)實現功能,可以根據使用(yong)要(yao)求變化進行定制。
3、工作方式為(wei)非接觸,避免傳統電位器的磨損,壽命(ming)長,可靠性高。
4、由于取(qu)消了傳統電位器中的電刷基片(pian),有效行(xing)程(cheng)達(da)到360°,實現無盲區測量(liang)。
5、輸(shu)出信(xin)號類型(xing)多(0-5V/0-10V/4-20mA/串行數字信(xin)號輸(shu)出),方(fang)便信(xin)號采集處(chu)理。
6、可以通過軟件實現有效(xiao)行(xing)程和輸出(chu)信號的變化,滿(man)足各種特(te)殊要求。
二、電子電位器的原理是什么
電(dian)子電(dian)位(wei)器(qi)(qi)采(cai)用(yong)(yong)傳感器(qi)(qi)原理生產,有(you)很好的線性(xing)、精度與溫(wen)度穩定性(xing)。采(cai)用(yong)(yong)軟件實現(xian)功能,可以根據使用(yong)(yong)要求變(bian)化進(jin)行定制。那么電(dian)子電(dian)位(wei)器(qi)(qi)的原理是什么?
常(chang)見的(de)(de)電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)位器一般都(dou)由角度(du)(du)(du)傳感(gan)器電(dian)(dian)(dian)(dian)路(lu)(lu)、數(shu)(shu)據(ju)處理電(dian)(dian)(dian)(dian)路(lu)(lu)和信號(hao)轉(zhuan)換(huan)(huan)電(dian)(dian)(dian)(dian)路(lu)(lu)組(zu)成。角度(du)(du)(du)傳感(gan)器電(dian)(dian)(dian)(dian)路(lu)(lu)是電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)位器的(de)(de)重要組(zu)成部分,它將角度(du)(du)(du)變化量(liang)(liang)采集(ji)轉(zhuan)換(huan)(huan)成隨角度(du)(du)(du)變化的(de)(de)模擬(ni)信號(hao)。數(shu)(shu)據(ju)處理電(dian)(dian)(dian)(dian)路(lu)(lu)是一種特殊的(de)(de)模/數(shu)(shu)轉(zhuan)換(huan)(huan)電(dian)(dian)(dian)(dian)路(lu)(lu),轉(zhuan)換(huan)(huan)后的(de)(de)數(shu)(shu)字量(liang)(liang)代表0~360°的(de)(de)角度(du)(du)(du)值(zhi)。信號(hao)轉(zhuan)換(huan)(huan)電(dian)(dian)(dian)(dian)路(lu)(lu)根據(ju)需要將角度(du)(du)(du)值(zhi)轉(zhuan)換(huan)(huan)成模擬(ni)量(liang)(liang)(電(dian)(dian)(dian)(dian)壓/電(dian)(dian)(dian)(dian)流)信號(hao)或(huo)串(chuan)行數(shu)(shu)字信號(hao)輸出。
