Principle of industrial handle
What is the basic working principle of industrial handle? First of all, when the industrial electronic control handle is used as a current regulator in the DC circuit, the current will pass through the sliding arm of the industrial electronic control handle. Due to the effect of anodic oxidation, the resistance value will increase abnormally. In this case, it is recommended to connect the terminal connecting the resistor to the negative pole and the sliding arm to the positive pole. If DC current passes through the industrial electronic control handle directly, the anode of the industrial electronic control handle will be oxidized and damaged, increasing the impedance of the industrial electronic control handle. Therefore, it is recommended to connect the cathode of the current to the terminal in contact with the carbon diaphragm and the anode to the terminal in contact with the brush (industrial electric control handle contact). When the industrial control handle is used as a variable resistance, it is recommended to use it as a voltage divider. The load resistance R1 of the electric control handle should not be less than 10 times of the nominal resistance RT, which is used to adjust the output voltage of the voltage regulator. Therefore, the industrial electric control handle should be designed to increase the output voltage when it is adjusted clockwise, Reduce the output voltage in time when adjusting counterclockwise. In the adjustable constant current charger, the industrial electronic control handle should be used to adjust the charging current multiple. The industrial electronic control handle should be designed in a clockwise direction, and the current will increase when adjusting the handle.
When designing the printed circuit board diagram of the electric control handle and using the integrated circuit board, the industrial handle should pay special attention to whether the positioning slot on the integrated circuit board is placed correctly and whether the position of each integrated circuit pin is correct. When the square wave pulse width changes, the angle of the steering gear shaft of the electric control handle changes to drive the motor forward and backward. The angle change is proportional to the pulse width change. The pulse width modulation signal of the electric control handle enters the signal demodulation circuit after being demodulated by the 12 pins of the receiving channel. The industrial electric control handle obtains the DC offset voltage. The input of the control line is a periodic square wave pulse signal with adjustable width. The period of the square wave pulse signal is 20ms.
What are the characteristics and application fields of industrial handle? Let's introduce it to you.
1. With long service life, the electronic control handle itself has the advantages of strong anti-interference ability, stable and accurate signal transmission, and can be applied to parameter adjustment in various scenarios, thus realizing more complex system debugging.
2. The structure is simple. The electric control handle can insert the harness into the terminal board safely and quickly by means of screw fixation or welding, which not only shortens the wiring time, reduces the cost, improves the production efficiency, but also avoids the impact of external damage on normal use.
3. Industrial handles are widely used in construction machinery, logistics handling, aerial work, video security, automobile production and other fields.
