Control instrument
The technological process of the control instrument: plug-in → welding → debugging → assembling.
Plug-in: First select a high temperature resistance resistor. High-quality wiring terminals, insulating tape and insulating particles, and then the raw materials are made into shapes. According to the actual situation, there are two production methods: manual molding and machine processing. After that, the MOS tube is installed on the aluminum bar according to the process requirements, and the raw material is plug-in processing.

Soldering: First, arrange the components and wiring harness of the control board, and then attach flux to the PCB board. There are three methods: foaming machine type, spray type, and dipping flux. After completion, a preheat treatment is required. The temperature of the preheater is controlled at about 150°C, and the control board is placed above the preheater for about 3 seconds. Next, perform welding. After the welding is completed, the control board is dip-soldered, and then the feet are cut and the copper wire is covered.

Debugging: Debugging is carried out through procedures such as visual inspection, power-on viewing, functional testing, discharge, and spraying of three-proof paint.

Assembling: consists of three steps: shell installation, insulation test and finished product test.

In this way, the production of the control instrument is completed.

2.How to Troubleshoot Control Instrument

In the process of long-term use of the control instrument, it is inevitable that some unexpected failures will occur. When a fault occurs, timely troubleshooting will effectively save time. The first step in troubleshooting is to determine whether the fault occurs inside or outside the instrument.

The external wiring of the control instrument has power supply, input signal and output signal. Therefore, when an abnormal phenomenon is found in the display, first use a multimeter to test the signal at the rear terminal, and it should be within the value required by the meter. By checking the signal on the rear terminal of the control instrument, it can be determined whether the fault is inside or outside the instrument. When it is confirmed that the fault occurs in the instrument, the specific part of the fault in the instrument can be further judged according to the fault phenomenon.

The main reasons for the failure of the control instrument are poor grounding of the instrument, unstable power supply, open circuit of the power transformer shielding, failure of the reference voltage and negative power supply in the control instrument, poor contact of the potentiometer, poor power filtering and voltage regulation, and automatic zero adjustment circuit Damaged and the connections in the table, the connectors or components have virtual soldering or poor contact, etc. Just find out the cause of the malfunction and solve it symptomatically.

3.Types of Control Instrument in the Market

There are many types of control instruments on the market. According to the energy used, it can be classified into three types: electric, pneumatic and hydraulic. According to the structure, it can be divided into base type and unit combined type. When you need to buy a control instrument, you can choose according to the actual situation you use.

1. Base-type control instrument: Mainly refers to all parts of the instrument, connected by an inseparable mechanical structure, and installed in a box. A single control instrument can solve all the problems of measurement, recording and control of a simple automation system.
2. Unit combined control instrument: including transmission, adjustment, calculation, display, execution and other units. Standard signals are used to connect each unit. When the instrument is in use, it is necessary to combine the units according to certain requirements.

4.How Control Instrument Works

Control instruments, instruments that automatically control the controlled variables. Its work content is to compare the measured signal with a given value, calculate the deviation signal according to a certain control law, and output the operating result with a specified signal. In general, control instruments are the instruments that constitute a process control system.

The main working principle of the control instrument is to compare the measured value of the controlled variable to be controlled with the required set value to obtain the deviation. According to a certain functional relationship, the control function occurs, and the control valve or other actuators are manipulated to realize the control of the production process. Commonly controlled variables in chemical production include temperature, flow, pressure, liquid level and composition. Conventional control instruments use analog signals to communicate and calculate internally, so they are called analog control instruments, also called regulators.

5.Industries using Control Instrument

The control instrument is used to keep the chemical process parameters within the specified range according to a certain precision, or to change the parameters according to a certain rule, so as to realize the control of the production process. Therefore, the control instrument can be used in conjunction with various sensors and transmitters to realize the measurement and display of physical quantities such as temperature, pressure, liquid level, capacity, and force, and cooperate with various actuators for electric heating equipment and electromagnetic and electric valves. Carry out PID adjustment and control, alarm control, data acquisition and recording.

Nowadays, the application range of control instruments is very wide. It is widely used in industry, agriculture, transportation, science and technology, environmental protection, national defense, culture, education and health, and people's lives.

7. What is the difference between control instrumentation and instrumentation equipment?

Control instrumentation and instrumentation equipment are two different existences, which are essentially different. The control instrument not only has the function of displaying the status of the equipment, but also has the function of feeding back data to the control main device, so that the control main body can adjust the equipment state in time, thus forming a closed control mechanism. The instrument equipment only has the most basic display function, does not have the feedback function, it is a one-way input device.

8. Control Instrument Maintenance Process

If you want to effectively extend the use time of the control instrument, you need to maintain the control instrument reasonably in the daily use process. The available maintenance methods are as follows:
1. Before use: Check the control instrument carefully to ensure that the control instrument will not cause any malfunction. It includes checking whether the indication and recording of the instrument are normal, checking whether the power and air source of the instrument reach the rated value, and checking the heat preservation and heat tracing status of the instrument. Check the damage and corrosion of the instrument body and connecting parts, and check the intact condition of the instrument, etc. It is necessary to ensure that the parts of the control instrument are complete and meet the technical requirements.
2. In use: follow the principle of fair use in use. For example, keep the whole machine clean, free of rust, and the coating should be smooth, bright and not falling off. The pipelines and circuits of the control instrument should be fixedly installed, and the numbers of the pipelines and circuits should be complete, clear and accurate.
3. After use: Reasonable maintenance should be carried out after use, and the control instrument should be cleaned in time. Set the time for maintenance and perform maintenance at regular intervals to prevent major failures. Damaged parts should be replaced in time, and operation records, fault records, and parts replacement records should be accurate.
