A dew point meter is an instrument that can directly measure the dew point temperature. A mirror is cooled in the humid air of the sample until the moment when dew droplets (or ice crystals) appear on the mirror surface, and the average temperature of the mirror surface is measured, which is the dew point (frost) temperature. It has high humidity measurement accuracy, but requires a mirror surface with high smoothness, a temperature control system with high precision, and an optical detection system for dew droplets (ice crystals) with high sensitivity.

A wind turbine is a device that converts the kinetic energy of wind energy into electrical energy. Thousands of large turbines grouped together, known as wind farms, now generate more than 650 gigawatts of electricity. They are an increasingly important source of intermittent renewable energy used in many countries to reduce energy costs and reduce reliance on fossil fuels. In this article, we will help you understand how they convert wind energy into electricity.

A power line filter is an electrical apparatus that efficiently filters that frequency in a power line as well as any other frequencies. The purpose of a power line filter is to access a power line filter in the power line and receive a power signal of a particular frequency or delete a power signal after a particular frequency.

It is a passive two-way network with the power supply at one end and the load at the other. As a result, it is an impedance adaptation network. Because of the characteristics of the power port's electromagnetic interference and design, power line filters are typically low-pass type, which is important for electronic products because electromagnetic noise causes interference from other equipment with electronic products.

A magnetic stirrer is a device that forces liquid and gas media to convect and mix uniformly. The type, size, speed, power and other parameters of the agitator have an important impact on the effect of media stirring and mixing. Different stirring processes need to be realized by the operation of different stirring devices. When selecting the type, first of all, the purpose and requirements of the stirring operation should be based on the process. The following is an introduction that how to troubleshoot magnetic stirrers.

Easy installation and maintenance, large sewage pumps are generally equipped with automatic coupling device can be automatically installed, installation and maintenance is quite convenient. Long continuous operation time. Because the pump and motor are coaxial, the shaft is short, and the rotating parts are light, the load on the bearing is relatively small, and the life of the pump is much longer than that of the general pump. In this article, we introduce four types of sewage pumps.

With the development of society, electricity is more and more important to our life. Modern society also relies heavily on electrical powered appliances. When there is a power failure, the power to these devices is cut and they stop working. In order to solve these problems of power failure and no power available, ups inverters and ordinary inverters are designed. Both ordinary inverters and ups inverters are used to provide backup power for electronic equipment in the event of a power outage. But there are some differences between them, which will be mentioned in this article.

Gloss meter is an instrument used to measure the surface gloss of ceramics, paints, inks, plastics, marble, aluminum, hardware and other materials. High-precision gloss meters are classified into three types according to the angle, including high-gloss, medium-gloss and low-gloss. As a professional instrument for detecting the gloss of the external surface of objects, the gloss meter is widely used in chemical raw materials, paint manufacturing, aerospace industry, automobile industry, shipbuilding industry, electronic industry, electrical industry, IT communication, etc. Now we will talk about gloss meter application in several different areas.

Linear guide is used to support and guide the moving parts, in a given direction to do reciprocating linear motion. It consists of steel balls rolling infinitely between the slider and the guide rail so that the loaded platform can move linearly along the guide rail easily with high precision. Linear guide is a kind of high precision product, the requirements for each component are very high. Linear guide has many advantages, in this article, we will explain in detail.

UPS uninterruptible power supply is a type of uninterruptible power supply that includes energy storage equipment. So what are the protection functions of UPS uninterruptible power supply? When the utility grid is suddenly cut off, the UPS will immediately convert the DC power of the UPS power supply battery into AC current and continue to deliver power to the load to prevent troubles and losses caused by power cuts.

Magnetic stirrers are laboratory instruments for liquid mixing, mainly for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixtures. The basic principle is to use a magnetic field to push the magnetic stirring bar placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, the sample temperature can be heated and controlled according to the specific experimental requirements, maintaining the temperature conditions required by the experimental conditions, and ensuring that the liquid mixing meets the experimental requirements.

Magnetic stirrers have become a wide variety of low-cost laboratory routine equipment, which enables us to have the ability to choose the magnetic stirrer that we need. Faced with many types of magnetic stirrers with different prices on the market, how should we choose? For applications that only require stirring at room temperature, choose a simple magnetic stirrer with only stirring function. For applications that require stirring and heating at the same time, and the temperature requirements are not very strict, a standard heating magnetic stirrer should be selected.

The magnetic float level sensor is suitable for liquid level or interface measurement in open or closed pressure vessels. It is a float switch that uses a magnetic float as a sensing element, and reflects the measured liquid level or interface through the coupling between the magnetic float and the magnetic body in the display color bar. However, how to maintain a magnetic float level switch in winter?

Every time we use the gloss meter, we must first calibrate the gloss meter. The purpose of calibration is to eliminate the influence of changes in the intensity of the light source and environmental changes each time the machine is turned on. This step of calibration is very important. If the calibration is not done well, the measurement will be greatly affected. Therefore, during the calibration process, it is necessary to ensure that the bottom surface of the gloss meter and the calibration plate are in very close contact. So how to calibrate gloss meter?

Stirrers, as one of the most commonly used moving equipment, are widely used in chemical, food, dye, cosmetic, and pharmaceutical industries. At present, magnetic stirrers are becoming a popular trend in the biopharmaceutical industry. The stirrer is a device that forces liquid and gaseous media to convection and mix them uniformly. Mixers of all kinds have been in use long before the Industrial Revolution. After the industrial revolution, the application of agitators has become more and more diversified and specialized.

The use of linear guide in machine tools is to guide and support the role. This role can be said to be very important in production, not only to improve the efficiency of production, the key is to have a great guarantee of product quality. Linear guide rust phenomenon, it is inevitable to encounter. Especially in hot summer like now, direct contact with the linear guide rail after the operator's hands are sweaty may also lead to rust of the guide rail. How should we try to avoid the surface rust of linear guide in daily use? In this article, we'll go into more detail and tell you how to solve it.

Leakage currents present a possible risk to patients in the unique setting of a hospital, placing additional demands on the electrical design. Medical IT systems (medical isolation transformers, etc.) must be installed in particular in locations where patient safety is crucial, such as operating rooms, intensive care units, and cardiac operating rooms. These locations must also have a steady power supply for the medical equipment they house.

Medical isolation transformer has strong anti-interference ability, which can effectively eliminate the noise, clutter, high voltage, surge and so on on the power grid, so as to provide a high-quality electric environment for the customer's equipment.

What is the transformer?

The transformer is made up of an iron core (or magnetic core) and one or more windings of a coil. The primary winding of the coil, which is linked to the power source, is referred to as the primary coil, and the remaining windings are referred to as the secondary coil.The simplest iron core transformer consists of two coils with unequal numbers of turns mounted on the core and a core made of soft magnetic material.

The core's function is to make the magnetic coupling between the two coils stronger.The core is made of a laminated silicon steel sheet that has been coated; there is no electrical connection between the two coils, and the coils are wound using insulated copper (or aluminum) wire to reduce eddy currents and hysteresis losses in the iron. The primary coil (or primary coil) is the coil connected to the AC power source, and the secondary coil is the coil connected to the appliance (or secondary coil).

Electricity, which is immediately changed by the generators of hydroelectric power stations and power producing stations, is widely employed as an energy source in modern industrial businesses. Depending on the transmission distance, the electricity produced by the generators will be transmitted at various voltage levels, hence a special device known as a "control transformer" is required to modify the voltage. It is a conversion tool because, in daily life, the power of various control transformer models is not the same, and the voltage and current limit values used are also different. However, electricity is transmitted from the same location, but the value required for each region is different. As a result, our transformer was developed to address these issues.Here we will take you through the purpose of control transformers.

Gloss is a physical quantity that evaluates the ability of a material surface to reflect light under a set of geometrically specified conditions, with directional selective reflection properties. The gloss we usually say refers to mirror gloss, so the gloss meter is sometimes called mirror gloss meter. Gloss is quite different from the machining industry's concept of finish or roughness, which is a continuation of the tiny unevenness on a material's surface.

Gloss meter, as known as gloss tester, is used in gloss measurement for paint, marble, ceramic, plastic, metal, etc. Gloss meter is widely used in chemical raw materials, paint manufacturing, aerospace industry, automobile industry, car maintenance, floor polishing, electronics, electrical appliances, IT communications and other industries. But how to choose a gloss meter?
