In industrial automation, sensors play a vital role to make products intelligent and super-automated. Sensors help people to detect, analyze, measure and process various changes, such as changes in position, length, height, exterior and misalignment that occur in industrial production sites.
A sensor is a device that can identify electrical or physical or other quantitative progress and deliver revenue by confirming the production progress. In short, industrial automation sensors are input devices that provide outputs (signals) related to specific physical quantities (inputs).
Sensors also play a pivotal role in predicting and preventing many potential processes, thereby satisfying the needs of many industrial sensing applications.
Various sensors used in automation include pressure sensors, temperature sensors, MEMS sensors, torque sensors, magnetic switches, proximity switches, photoelectric sensors, optical fiber sensors, displacement sensors, micro switches, etc.
The power switch button can complete basic controls such as start, stop, forward and reverse rotation, speed change, and interlock. Each push button switch has two pairs of contacts. Each pair of contacts consists of a normally open contact and a normally closed contact.
In order to indicate the function of each button and avoid misoperation, the button caps are usually made of different colors to show the difference. Its colors are red, green, black, yellow, blue, white, etc. Red means stop button, green means start button, etc.
Overhead crane lifting operation is a common job. However, in this work, the hidden dangers of the overhead crane in the lifting operation can easily cause corresponding leakage.
The button switch is a low-voltage switch device used to cut off and switch on the control circuit. The rated current of the contact of the button switch is 5A. Therefore, the circuit controlled by the button switch is a small current circuit. There are emergency stop button, start button, up, down, left, right, front and back buttons on the remote control of bridge crane. Pressing the abort button is very important. Its main function is to stop when there is a risk. For example, when the bridge crane is sliding, the sliding hook can be manipulated by pressing the emergency stop button.
The emergency stop button should be pressed immediately after the bridge crane is used. Because if the emergency stop button is not pressed, the bridge crane is powered on. If you don't touch the key, other accidents may occur. Long-term electrification will also affect the service life of electrical components. For example, the warning light will flash for a long time, and the overload limiter will remain in working condition. With the passage of time, the service life of these electrical components will be shortened.
The emergency stop button is similar to the power button and unlock function on a mobile phone. When we use mobile phones, we will turn on the power button and unlock, and then press the power button to turn off the power.
The wireless remote control crane can meet a variety of different production environments. In the electrical automatic control circuit, manual button switches can send out control signals to control contactors, relays, electromagnetic starters, etc.
