Moisture meter (moisture tester) is an instrument for quickly measuring moisture content. It is mostly used for moisture control in various industries such as food, chemical industry, plastics, agriculture and forestry. According to different working principles, moisture meters can be divided into the following types.

An air filter is a device composed of fibrous or porous material that removes solid particles such as dust, pollen, mold, and bacteria from the air. Filters containing adsorbents or catalysts also remove odors and gaseous pollutants. Air filters are generally used in clean workshops, laboratories and clean rooms, or for dust prevention of electronic mechanical communication equipment. There are many types of filters. It is mainly divided into primary filter, intermediate filter, high efficiency filter and sub-high efficiency models. Various models have different standards and performance.

The industrial Ethernet has been wildly used in daily life. As an important component of the network, industrial switches play an important role in current industrial automation. Industrial field switches can be divided into two categories: unmanaged and managed. General device internal network, such as CPU. Unmanaged switches are used for data exchange between distributed modules; managed switches are used for communication between devices and the factory network. They all belong to the industrial ethernet switches. So, what is the difference between an unmanaged switch and a managed switch? Today we will talk about this topic.

Nowadays, the real estate development trend is increasingly prosperous, and the building floors are generally on the high side. Many people choose high floors when buying a house, because the view and lighting of high floors are good. But the pressure of tap water on high floors is definitely not as high as that of low-rise residents, so many families will install a booster pump to safeguarding of water supply. So how to install this booster pump? What should be paid attention to when installing a booster water pump? Let’ have a look together.

As automation matures and rises with the extensive use of industrial Ethernet and the establishment of large-scale industrial control networks. Industrial Ethernet switches are also widely used in the field of industrial control. At present, the three-layer industrial Ethernet switch shows a strong growth trend and is replacing routers in the local area network. Its huge market potential is attracting a large number of domestic and foreign manufacturers to join the competition. When choosing a switch ( managed switch or unmanaged switch), faced with such a variety of brands, what aspects should users start with when choosing is a problem that must be solved.

The booster pump, namely a pump used for boosting. According to the substance of action, booster pumps can generally be divided into air pressure pumps and water booster pumps.

The accessories of the magnetic switch applied to the cylinder are also called magnetic cylinder sensors. Today, the combination of magnetic switches and cylinders is widely used in hundreds of fields such as robots, automation equipment, medical equipment, and transportation. So do you know how it works? The following content will provide you with a detailed working principle.

Smoke detectors and carbon monoxide detectors are two different instruments, and they have obvious differences in nature. Next, we will provide you with detailed information to explain their differences in different aspects.

The gyroscope sensor is an easy-to-use control system for free-space movement and gesture-based positioning. It was originally applied to helicopter models, and now it has been widely used in mobile portable devices such as mobile phones. For those unfamiliar with this type of product, the gyroscope sensor is an easy-to-use control system that based on the free-space movement and gesture positioning.

A rotary gear pump is a kind of rotary pump, which occupies a very important position in daily production. So do you know the concept of the rotary gear pump? Next ATO will introduce the information of rotary gear pump for you in detail.

A rotary gear pump belongs to the volumetric rotary pump, which has more than two internal gears that generate vacuum pressure by the mechanical movement of the gears, with the purpose of driving the movement of the fluid inside the pump.

The electronic speed controller (ESC) is an essential part of an electric propulsion system's hardware. It acts like the brain of the system by telling the motor how fast to go based on data signals it receives from the throttle controller. For smaller applications like drones and RC vehicles, this controller has the name ‘ESC', whereas for larger manufacturing applications it may be called an electronic control unit, inverter, or motor controller.

A rotary pump is a rotating pump, which can change the working volume through the relative motion between the rotor and the pump body to increase the energy of the liquid pump, often used in the transport of high viscosity media. So what types of rotary pumps are usually divided into? Let's have a look in the followings.

Hydraulic punches are widely used in outdoor work such as construction and power industries. The hydraulic punch is very suitable for punching various metal materials and can punch out various hole types.

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.

In the AC multi-stage amplifier circuit, due to the different gain and power of each level, the DC working offset value of each level is different. If the direct coupling between the stages will make the working offset value of each level mixed and cannot work normally. The AC and DC isolation feature not only solves the coupling of the inter-stage communication, but also isolates the inter-stage bias value from mixing.

A spectrophotometer is a measuring instrument that samples reflective or transmissive objects with discrete wavelengths. Due to the different molecular structures of different objects, the ability to absorb light of different wavelengths is also different. Therefore, each object has a specific absorption spectrum. A spectrophotometer separates each monochromatic light from a mixture of wavelengths and measures its intensity.

The ball valve is evolved from the plug valve. It has the same lifting action of rotating 90°, the difference is that the cock body is a sphere with a circular through hole or channel through its axis. The ratio of the spherical surface to the channel opening should be such that when the ball rotates 90°, all spherical surfaces should appear at the inlet and outlet, thereby truncating the flow. The ball valve can be closed tightly with only a 90° rotation operation and a small torque. The completely equal valve body cavity provides a low resistance, straight-through flow path for the medium.

Thermal overload relays are overload relays that apply the principle of current thermal effect and use electrical thermal bimetallic sheets as sensitive components. The electrical thermal bimetal sheet is made by heating and rolling two alloys with large difference in linear expansion coefficient. When heated, the bimetallic sheet bends from the high expansion layer to the low expansion layer. When the current is too large, the element acts due to "heat", so that its linked moving contact cuts off the power supply of the controlled circuit and the protected equipment.

The Diaphragm pump, also known as control pump, is the main type of actuator. It changes the fluid flow with the help of power operation by receiving the control signal output by the adjustment control unit. The function of the diaphragm pump in the control process is to accept the control signal of the regulator or computer, change the flow rate of the adjusted medium, and maintain the adjusted parameters within the required range, so as to achieve the automation of the production process.
