地磅传感器几种常见故障及其解决办法说明

作者:admin 发布日期:2019-12-08 关注次数:1086

一、地磅传感器电缆松动掉落

在(zai)传(chuan)(chuan)感器(qi)运送(song)或(huo)运用过程中,有时人们不留意,喜爱拿(na)着(zhe)传(chuan)(chuan)感器(qi)的引线嘴子,提(ti)起整只传(chuan)(chuan)感器(qi)。关于量(liang)程大的传(chuan)(chuan)感器(qi)来说,本身较重,那样(yang)会 使(shi)传(chuan)(chuan)感器(qi)电缆松动,有时会扯掉下 来。

发(fa)生这种现象时,应将传感器(qi)独(du)自取下来,拧下接(jie)嘴子(zi),将掉下来的电缆芯焊上。留意要按(an)原来的方位焊线(xian)(xian)。假如(ru)现已(yi)无法辨(bian)认,则需要翻(fan)开接(jie)线(xian)(xian)盒的盖子(zi),要保证引(yin)线(xian)(xian)内外(wai)的颜色(se)一致。

二、地磅传感器绝缘欠好

因为传感(gan)器(qi)运用场所(suo)环境(jing)有时(shi)十分湿润,假如传感(gan)器(qi)接线腔封欠(qian)好(hao),加之接线焊点不(bu)洁净,以及(ji)某些辅助(zhu)材料吸(xi)潮(chao),就(jiu)有可(ke)能形成传感(gan)器(qi) 绝缘欠(qian)好(hao)。反映在测验外表上(shang),就(jiu)是读数不(bu)稳定,数字上(shang)下(xia)跳动。

扫除这类毛病时,一般是将(jiang)传感器(qi)接线腔的(de)(de)盖(gai)子翻开,用洁净的(de)(de)绵签(qian)或(huo)纱布,浸上(shang)(shang)酒(jiu)精或(huo)丙酮,将(jiang)接线板的(de)(de)焊点悄悄擦拭,一起用电(dian)(dian)吹(chui)风对(dui)着接线腔吹(chui)。留意(yi)电(dian)(dian)吹(chui)风不(bu)要离接线太近,以(yi)免(mian)使(shi)接线过(guo)热导致外皮老化。假如(ru)有(you)条件(jian),在(zai)擦拭完之后,可(ke)将(jiang)传感器(qi)放人(ren)烘干箱中(zhong),在(zai)髙温60℃-70℃下进行烘烤,冷却后测(ce)量绝缘。假如(ru)合(he)格,应立即按原样将(jiang)接线腔密封;假如(ru)不(bu)合(he)格,则(ze)可(ke)接照上(shang)(shang)述(shu)办法进行一两(liang)次循环。

三、地磅传感器连接线与外壳短接发生这种现象时


反应(ying)在(zai)测验表上的(de)状况,与(yu)绝缘欠好时(shi)大致相同:也是(shi)呈现跳字、读数(shu)不(bu)稳。这很(hen)可(ke)能是(shi)在(zai)封装盖(gai)子的(de)时(shi)侯(hou),不(bu)小(xiao)心(xin)将(jiang)接线板(ban)上的(de)焊点与(yu)外壳(qiao)相接,或(huo)是(shi)压盖(gai)时(shi)将(jiang)连线压伤外皮与(yu)外壳(qiao)相连。


呈(cheng)现这种状(zhuang)况(kuang)时(shi),可将传感(gan)器接(jie)线(xian)(xian)腔盖子(zi)(zi)翻(fan)开,查看连线(xian)(xian)是(shi)否(fou)损(sun)伤(shang)外(wai)皮,或(huo)许看看接(jie)线(xian)(xian)板固定(ding)怎么。从(cong)头(tou)调整后,再将接(jie)线(xian)(xian)腔盖子(zi)(zi)密封。

四、地磅传感器断线

假如是(shi)传感器(qi)(qi)输(shu)入端(duan)断(duan)线(xian),反映在(zai)(zai)测验(yan)外表上(shang),传感器(qi)(qi)加(jia)荷时输(shu)出没有改(gai)变。假如不是(shi)传感器(qi)(qi)输(shu)人端(duan)断(duan)线(xian),在(zai)(zai)测验(yan)外表上(shang)会显现断(duan)路状(zhuang)况(kuang),数(shu)字闪烁。

呈现传(chuan)(chuan)感器(qi)断线(xian)(xian)(xian)(xian)(xian)(xian)(xian)时,应(ying)首要(yao)查看(kan)电缆(lan)线(xian)(xian)(xian)(xian)(xian)(xian)(xian),接(jie)(jie)下来看(kan)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)嘴于是(shi)(shi)否(fou)松动,电缆(lan)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)有没(mei)有改变。假如(ru)(ru)电缆(lan)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)不存(cun)在(zai)问题,接(jie)(jie)着查看(kan)接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)腔内,接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)板(ban)上(shang)的(de)(de)各连接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)断线(xian)(xian)(xian)(xian)(xian)(xian)(xian),如(ru)(ru)断线(xian)(xian)(xian)(xian)(xian)(xian)(xian)则应(ying)将其焊上(shang)。假如(ru)(ru)接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)腔也没(mei)断线(xian)(xian)(xian)(xian)(xian)(xian)(xian)(此种(zhong)状况很少见),那就可能是(shi)(shi)弹 性体上(shang)应(ying)变片的(de)(de)连线(xian)(xian)(xian)(xian)(xian)(xian)(xian)断了(le),或是(shi)(shi)在(zai)传(chuan)(chuan)感器(qi)由内部往接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)腔引线(xian)(xian)(xian)(xian)(xian)(xian)(xian)时断线(xian)(xian)(xian)(xian)(xian)(xian)(xian)。关于全密封(feng)(feng)式的(de)(de)传(chuan)(chuan)感器(qi),这种(zhong)毛病的(de)(de)扫除(chu)几乎是(shi)(shi)无(wu)能为力,只要(yao)切开外壳进行接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)了(le)。关于象铝传(chuan)(chuan)感器(qi)那样(yang)用胶封(feng)(feng)的(de)(de)传(chuan)(chuan)感器(qi)则可以(yi)去掉胶层,从(cong)头接(jie)(jie)线(xian)(xian)(xian)(xian)(xian)(xian)(xian)。
