Firstly, field measuring instruments are generally divided into four categories.Analysis of Common Faults in One Temperature Instrument System(1) Temperature suddenly increases: This fault is mostly caused by thermal resistance (thermocouple) circuit breaking, loose wiring terminals, (compensation) wire breaking, temperature failure and other reasons. At this time, it is necessary to understand the location and wiring layout of the temperature. The reason can be quickly found out by measuring several sets of data with Multimeter resistance (millivolt) gear at different locations.(2) Temperature suddenly decreases: this fault is mostly caused by short circuit of thermocouple or thermal resistance, short circuit of conductor and temperature failure. We should start with the weak points which...
