Today we are going to introduce the last method of transmitter fault checking – the divisional method. Simply put, the divisional method is the method of dividing the circuit and electrical parts into several parts in the process of fault finding to identify the cause of the fault. The circuit of a general test transmitter can be divided into three main parts, the external circuit, the power supply circuit and the internal circuit. External circuit: All circuits from the terminal of the transmitter to the detection element and the control actuator. Power supply circuit: All circuits from the AC power supply to the power transformer. Internal circuit: All circuits other than the external circuit and power supply circuit. The internal circuit can be divided into several small parts according to the characteristics of the internal circuit and the structure of the electrical components. Partial inspection hair is based on the division of the various parts, take the outside to the inside, from big to small, from the table to the inside of the method of checking each part of the transmitter, and gradually narrow down the scope of suspicion. When the inspection judgment in which part of the fault, and then do a comprehensive inspection of this part, to find the fault parts of the transmitter. Partial inspection of the order of the transmitter parts of the inspection and analysis of judgment, is more organized, but the inspection time is long, in the inspection often can not catch the focus, will waste a lot of time. Therefore, the divisional method is adapted to the maintenance of less experience in maintenance personnel, less familiar with the phenomenon of transmitter failure, and the failure of more complex cases. In the series of technical articles on “Judging Transmitter Failure Methods”, we introduced the direct observation method, investigation method, circuit method, resistance method, voltage and current method, division method, seven methods to determine the transmitter failure. In the actual production and use of the process, triggered by a variety of reasons for transmitter failure, the use of transmitters and maintenance personnel shall apply the appropriate ways and means, timely investigation of the causes of failure, so that the detection process more effective. Correct judgment of transmitter failure, but also to avoid the transmitter field use, the failure of the recurrence.
