The foot switch is a switch that operates the circuit by stepping on or stepping on it, and can also be used to control the size of the output current. The foot switch is a switch that controls the on-off of the circuit by stepping on or stepping on it. It is used in the control circuit that cannot be touched by both hands to replace the hands to achieve the purpose of operation.

Now we will introduce how to use a digital panel meter.
Vacuum generators are now widely used in many industries fields. It plays a huge role in industrial manufacturing. Today, we will introduce the working principle, classification, characteristics, selection of vacuum generators and functions. We hope you can have a general understanding of vacuum generators after reading this article.
A soldering station, a hand tool commonly used in electronic soldering processes, welds two pieces of work by applying heat to the solder (usually referred to as tin wire), causing it to melt. Today, we are going to introduce the functions, precautions, advantages of soldering station and the differences between soldering station and electric soldering iron. We hope that after reading this article, you can have a general idea about soldering station.
When we use a conventional contactor to control the rotation of a 3-phase motor, we usually need to exchange two of the three terminals to reverse the rotation.The output shaft rotates clockwise when L1, L2 & L3 are connected to U, V, W.
A single phase induction motor consists of a single phase winding on the stator and a cage winding on the rotor. When a 1 phase supply is connected to the stator winding, a pulsating magnetic field is produced. In the pulsating field, the rotor does not rotate due to inertia. The structure of the 1-phase motor determines that the reverse rotation is generally completed by hardware.
A current sensor is a detection device that can sense the information of the measured current, and can transform the sensed information into electrical signals that meet certain standards or other required forms of information output according to certain rules to meet the needs of Requirements for the transmission, processing, storage, display, recording and control of information.
Vacuum circuit breaker is an internal power distribution device in three-phase AC system with voltage of 3-10kV and frequency of 50Hz. In industrial and mining organizations, power plants and substations can be used to protect and control electrical equipment. The vcb circuit breaker can be configured in the middle cabinet, double-layer cabinet and fixed cabinet to manage and protect the high-voltage electrical equipment in the maintenance and frequent operation area.
A relay is an electrical control device. When the change of the input quantity (excitation quantity) reaches the specified requirements, the relay makes a predetermined step change of the controlled quantity in the electrical output circuit. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. Relays are widely used in industry. Therefore, today we will introduce the structure, function and classification of relays. We hope that after reading this article, you can have a general idea of relays.
Brushless DC motor kit consists of a motor and a driver, and is a typical mechatronic product. Because the brushless DC motor operates in a self-controlled manner, it will not add a starting winding to the rotor like a synchronous motor with heavy-load starting under variable frequency speed regulation, nor will it cause oscillation and loss of step when the load changes suddenly. Today we're going to study how to connect a brushless motor to a driver and control speed.
A voltage stabilizer is a power supply circuit or power supply device that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range, so that various circuit or electrical appliances can be stabilized. The equipment can work normally under the rated working voltage.
With new improvements in vacuum breaker design, vacuum circuit breakers are becoming more common at the lower voltage ranges of transmission networks. When choosing a vacuum circuit breaker, we need to consider many factors. But the most important thing is to know about vacuum circuit breakers before you can make a choice. The following brief introduction hopes to help you choose the right one.
An air compressor is a device that converts power into potential energy stored in compressed air. By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. Air compressors are widely used in industrial production to provide power for production. After the air is compressed, it can be used as power, machinery and pneumatic tools, as well as control instruments and automation devices. Ranging from the drive of various pneumatic machinery to the national defense, the power converted by the air compressor is used.
A gas detector is an instrument that detects gas concentration. The instrument is suitable for dangerous places with flammable or toxic gases, and can continuously detect the content of the measured gas in the air within the lower explosion limit for a long time. It can be widely used in gas, metallurgy, steel, coking, electric power and other industries where flammable or toxic gases exist. Gas detectors are ideal monitoring instruments to ensure property and personal safety. Therefore, today we are going to introduce gas detector to you. We hope that you can know why you need a general idea about gas detector after reading.
Thermocouple temperature sensors are characterized by wide range, low cost, fast response and durability. They are widely used for temperature measurement in industry. R-type thermocouples can measure high temperatures of more than 1700 degrees, and are mainly used in high temperature measurement occasions. In today's article, let's talk about how thermocouples work.
The temperature detection technology is relatively mature now, and the development changes are relatively small. The main change is that the temperature transmitter has developed rapidly and has entered into a new period of automation and intelligence. The protective performance of temperature detection instruments has been strengthened, such as anti-corrosion, explosion-proof, anti-corrosion, waterproof, etc. The selection of temperature detection methods is particularly important for its use and control in industrial sites. Appropriate measurement methods can get twofold result with half the effort. The following passage is brief description of temperature transmitter type.
Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum.
Solar radiation sensor is designed on basis of silicon-cell principle. It is mainly used for measuring solar radiation within 300-1100nm wavelength. If the sensing face is downwards, it can test the reflected radiation and solar radiation on the incident to the inclined plane. PAR sensor is mainly used for measuring solar radiation within 400-700nm wavelength. It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the silicon-photo detector in the sensor.
