1.在现场无检测标准仪器的情况下,如何判断温度显示仪表的好坏近几年,我们采用崔庆坤编著的“高温仪表修理”一书中所介绍的人体碱电地方法,收到了较好效果,具体方法是: 将现场出故障的测温显示仪表与测温元件(发送毫伏信号)的(?)(?)两个连接导线断开,在现场仪表盘或管线保温金属网上随便找一段铜线(铜丝),一段铁丝(铝丝),将铜线一端接于被检查仪表的(?)端子上,而将铁丝(铝丝)接入被检查仪表的(?)端子上,然后分别将铜丝或铁丝(或铝丝)另一端同时放在食指上,并且使两段金属丝不相接触,而后在食指上蘸少许唾沫,用拇指将二金属捏住,此时,被检查的仪表如无故障应有指示(指示高低与二段金属丝距离成反比,与唾沫多少成
1. In the absence of testing equipment at the scene, how to determine the temperature display instrument is good or bad In recent years, we use Cui Qingkun compiled “high temperature instrumentation repair ” a book described in the human body alkaline method, received Better effect, the specific method is: the scene of the fault temperature display instrument and temperature measurement element (send the millivolt signal) (?) (?) The two connecting wires off, on-site dashboard or pipe insulation metal Just look for a piece of copper wire (copper wire), a piece of wire (aluminum wire), connect one end of the copper wire to the terminal of the inspected instrument, and connect the wire (aluminum wire) to the terminal of the inspected instrument , And then the other end of the copper wire or wire (or aluminum wire) at the same time on the index finger, and the two wires do not touch, and then dip in the index finger a little spit, thumb two metal pinch, this time , Check the instrument should be instructed if there is no fault (indicating the level of wire is inversely proportional to the distance and the second paragraph, with how much saliva into
