A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.They can be used on any rotating object to transfer power, control circuits, or analog or digital signals including data such as those found on aerodrome beacons, rotating tanks, power shovels.

Both voltage stabilizer and voltage regulator are power protection devices. The voltage regulator can adjust the required voltage according to the actual situation of the user. The voltage stabilizer can only stabilize the fluctuating and unstable voltage at the preset voltage value in the factory. Although both the voltage stabilizer and the voltage regulator change the voltage, but their functions are different. You could choose according to the actual situation.

A monitoring relay is a commonly used electromagnetic relay that is used for the voltage protection and control of the power drag system. The coil is connected to the main circuit in parallel to sense the line voltage of the main circuit; the contact is connected to the control circuit and is the executive element. According to the size of the pull-in voltage, voltage monitoring relays can be divided into over-voltage relays and under-voltage relays. ATO monitoring relay has a great many function, including overvoltage protection, undervoltage protection, voltage unbalance protection, phase failure protection and wrong phase protection.

Thermal label printer is that a semiconductor heating element is installed on the print head, and the print head can print out the required pattern after heating and contacting the thermal printing paper. Its principle is similar to that of a thermal fax machine. The image is created by heating the membrane to create a chemical reaction. This thermal label printer chemical reaction takes place at a certain temperature. High temperatures speed up the chemical reaction. When the temperature is below 60℃, it takes quite a long time, even years, for paper to become dark. At 200℃, the reaction takes place in a matter of microseconds.

A solenoid valve is an on/ off electromechanically operated valve which consists of an electromagnetic actuator (solenoid) and a valve body. The solenoid-plunger assembly is the valve actuator responsible for opening and closing the valve. This actuator can be arranged in such a way that the plunger action can either open or close only. There is no intermediate, or in-between position, so there is no way for a solenoid to throttle flow. The valve body consists of the pressure containing parts in-contact with the process fluid.

The DC servo motor has many advantages, including low cost, simple structure, large starting torque, wide speed regulation range and easy control. It is easy to maintain (replacement of carbon brushes) and it has requirements for the environment. Therefore, it can be used in general industrial and civil occasions. Next we'll look at how to control DC servo motor speed with analog.

Stepper motor is an open-loop control motor that divides a full rotation into a number of equal steps. The motor's position can be controlled to move and hold at one of these equal steps. Stepper motors come in many different sizes and styles, and they are widely used in a variety of automated control systems.

The reactor has the function of passing DC and resisting AC in the circuit. When an unsteady current flows through a conductor, a changing magnetic field will be generated, which will in turn affect the current, so any conductor will have a self-inductance phenomenon. Reactors are widely used in the system. Based on years of operating experience, the author introduces several common faults and their solutions.

An oscilloscope is a very versatile electronic measuring instrument. It can transform invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena.Today we will introduce the features and applications of oscilloscopes. We hope that after reading, you can know the usage of oscilloscope.

Centrifuge machines can be categorized into industrial centrifuges and experimental centrifuges. Experimental centrifuges are divided into preparative centrifuges and analytical centrifuges. Preparative centrifuges are mainly used to separate various biological materials. The sample capacity of each separation is relatively large. Analytical centrifuges generally have optical systems. It is mainly used to study the physical and chemical properties of pure biological macromolecules and particles. According to the behavior of the substance to be tested in the centrifugal field (continuously monitored by the optical system in the centrifuge), the purity, shape and molecular weight of the substance can be inferred. Analytical centrifuges are all ultracentrifuges.

A push-button switch is an electrical appliance that is used to connect and disconnect small current circuits that is pressed to act and released to reset. It  is generally used in control circuits with AC and DC voltages below 440V and currents less than 5A. Generally, it does not directly manipulate the main  circuit, but can also be used in interconnecting circuits.

A gas detector is a kind of instrumentation tool for gas leakage concentration detection, including a portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. They mainly use gas sensors to detect the types of gases present in the environment. Gas sensors are sensors used to detect the composition and content of gases.

Variable frequency drives (VFDs) have most commonly been used in water treatment plants, where they're used to regulate water flow. But in recent years, they've grown in popularity throughout many areas of the industry.

In industrial electricity and household electricity, in order to use electricity safely and ensure the safety of people's property, we must use power conditioning equipment in the process of power transmission, and the voltage regulator is one of them. It can adjust the voltage of our daily electricity consumption, so that the power supply voltage can meet the requirements of our machinery and equipment. Voltage regulators are widely used in the automotive industry, energy-saving lighting, machinery and equipment, electric furnace industry, chemical industry, glass industry.

Torque sensors, also known as torque meters, are divided into two categories: dynamic and static. Dynamic torque sensors can also be called torque sensors, torque speed sensors, non-contact torque sensors, and rotational torque sensors, etc. Today we will introduce two types of torque sensor. We hope that after reading this article, you can have a better understanding about a torque sensor.

Computer Numerical Control (CNC) routers are a class of machine shop equipment used to remove material from specific locations on wood or metal. Since each material has different advantages and disadvantages, there are different types of CNC milling machines. Computer numerical control refers to computer programming used to control and program routers. CNC routers are used to create patterns or cuts as needed. Industrial CNC routers used in factory settings are much more expensive than hobbyist models. CNC routers are attached to a table and programmed to remove material in a specific pattern or shape from a piece of wood or metal. The engraving machine is usually connected to a three-speed or four-speed motor system.

The limit switch is a commonly used small current master electrical appliance. It utilizes the collision of the moving parts of the production machinery to make or break the control circuit to achieve certain control purposes. Usually, this ATO limit switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse movement, variable speed movement or automatic round-trip movement according to a certain position or stroke.

A sound level meter is a basic noise measuring instrument, which is an electronic instrument. But it is different from objective electronic instruments such as voltmeters. When converting an acoustic signal into an electrical signal, it can simulate the time characteristic of the human ear's response speed to the sound wave; the frequency characteristic with different sensitivity to high and low frequencies and the intensity characteristic of changing the frequency characteristic at different loudness. A sound level meter is a subjective electronic instrument.
