5.安装                                   

一般安装方式为:传感器探头管套焊接在管道(或被测设备)上,传感器旋紧在探头管套上。以下为抽油机油管安装说明,其它应用类似。

操作流程为(如图2所示)

(1)油管线阀门关闭、泄压泄空。在油管上开个比传感器探头底座外径稍大一点的孔;

(2)将底座从开孔处插入至最大深度,调整底座与被油流成45°倾角,然后沿孔一周密封焊接在油管上;

(3)底座内注入导热油,约2/5管的容积;

(4)温度传感器探头插入底座,以扳手卡在六方棱柱将传感器旋紧,管线阀门打开恢复。

6.电气连接

打开仪表后盖(接线端子面),见接线端子,电源连接见图4:其中左端 1(红)、2(黑)为传感器供电、信号接线,不分正负极,上端的4脚为接地线屏蔽线固定端。

7.注意事项

7.1.所有传感器经过数字化校准,不同的传感器间具备完全的一致性和互换性。

7.2.传感器供电、信号接线接入到三芯端子上的左端 POWER1+(红)、POWER 2-(黑),装好并拧紧后盖。要注意旋紧护套,防止漏水。
