For current signals, if the equipment has an independent power line, the signal output it provides (such as 4-20 mA) is active signal; If the device has no independent power supply, the signal it provides is passive. The output signal of three-wire instrument and four-wire instrument is active signal, and the output signal of two-wire instrument is passive signal. In this article, we will introduce the passive and actice signal.

A wind Meter (Anemometer) is an instrument for measuring airflow speed, which can be widely used in various fields, such as electricity, steel, petrochemical, energy-saving and other industries, in daily life, many industries need to use the wind anemometer, such as fan manufacturing, sea fishing industry, extraction and exhaust heating systems, etc., are required to use the anemometer for wind speed, wind temperature, wind measurement to ensure normal work.

The flow velocity measurement range from 0 to 100 m/s can be divided into three zones: low velocity: 0 to 5 m/s, medium velocity: 5 to 40 m/s, high velocity: 40 to 100 m/s. The anemometer's thermal probe is used for measurements from 0 to 5 m/s; the anemometer's rotor probe is most effective for velocities from 5 to 40 m/s; and the use of a pitot tube gives the best results in the high velocity range. An additional criterion for the correct selection of an anemometer flow probe is the temperature, which usually reaches about +-70°C for thermal sensors. Special anemometers have runner probes up to 350C. Pitot tubes are used above +350°C.

Linear actuators convert the rotary motion of the motor into a straight line. Traditional motors move in a circle, while linear actuators move forward and backward. Push and pull actions allow the device to slide, tilt and lift items with the push of a button. The design provides the operator with accurate and precise control over production. Fluid motion means linear actuators require minimal maintenance over their lifetime and are naturally energy efficient. They are easier to install, cost less and take up far less space than their hydraulic or pneumatic counterparts.

The wind speed test has the test of average wind speed and the test of turbulence component. The thermal anemometer is to test the average wind speed. The methods of testing the average wind speed are thermal, ultrasonic, impeller, and skin dragging tube, but in these methods, the anemometer is using the principle of heat dissipation. Below, a description of these types of anemometers is given.

Peristaltic pump is also called peristaltic metering pump, constant flow pump, peristaltic hose pump. A peristaltic pump is a liquid transmission device that can control the flow rate. By repeatedly compressing the elastic tubing, the liquid in hose moves in a certain direction, and its flow rate is determined by the diameter of tubing and the compression speed. The liquid is delivered by alternately squeezing and releasing the elastic delivery hose of the pump. In this article, we will introduce structure, working principle and selection of peristaltic pump.

Electrolytic capacitor is a kind of capacitor, the metal foil is the positive electrode (aluminum or tantalum), the oxide film (aluminum oxide or tantalum pentoxide) close to the positive electrode is the dielectric, and the cathode is made of conductive material and electrolyte (the electrolyte can be liquid or tantalum pentoxide). Solid) and other materials together, because the electrolyte is the main part of the cathode, so the electrolytic capacitor is named.

Customized equipment, also known as non-standard equipment, is a type of integrated automated equipment that is specifically designed as customers desire and not circulating on the market. In this video, we’re gonna show you a non-enclosure VFD that is specially built for custom-made equipment.

Submersible sewage pump is a, solids-handling pump with a large outlet and a powerful motor, designed to move liquid and sewage waste up to 2 inch in diameter. Sewage water submersible pump is generally used in a basement, where plumbing fixtures such as sinks, showers and toilets as well as laundry equipment are located below the level of municipal sewage discharge pipe and therefore cannot be drained by conventional gravity means. ATO provides various types of submersible sewage water pumps, such as 1 hp sewage pump, 1.5 hp sewage pump, 2 hp sewage pump and 3 hp sewage pump.

The main function of the capacitor of the electric fan is that the capacitor and inductor in the electric fan have the function of phase shifting, the terminal voltage of the capacitor is 90 degrees behind the current, and the terminal voltage of the inductor is 90 degrees ahead of the current. First of all, capacitor phase shifting, once the capacitor is energized, the circuit charges the capacitor, and the voltage tends to 0 at the beginning when the charging current is the maximum.

Today in this article, we're gonna show you a permanent magnet synchronous motor, or PMSM that features high efficiency and high dynamic performance and wring. Based on the location of the shat there are two types of PMSMs, those with central shafts and the others with non-central shafts. The model we present in this article is one of the former type, a PMSM of 60TYD series with a rating of 110V, 50Hz, 5rpm and 14W that can provide continuous rotation.

The inverter converts DC (batteries, accumulators) to AC. In general, an inverter is an electronic device that converts low-voltage (12, 24, 48 volts, etc.) DC power into 220V AC (or other voltage) power. It consists of an inverter bridge, control logic and filtering circuit. When there is no output from an inverter, what's the reason?

Locking plug is known as NEMA connectors. NEMA stands for the National Electrical Manufacturers Association, a USA-based organization that forms a set of globally recognized and internationally applied standards for the manufacturing of electrical equipment. These standards outline the voltage and amperage configurations of plugs and receptacles to make it easier for consumers to differentiate them. NEMA connectors, including power plugs and receptacles, are among the electrical product categories covered by NEMA standards.

Modern industrial automated machinery is powered mostly by motors. The torque generated from a rotating motor provides the driving force for moving conveyor belts, gears, chains and other mechanical components, so a motor naturally becomes such an integral part that is key to the driving system. When it comes to the protection of the core power part, you can't pay too much attention to it. Thermal overload relays are used to provide overload protection, open-phase protection and protection against the unbalanced current for motors and they can also avoid heating in electrical equipment. The thermal overload relay works by the thermal effect of electric current to push the action mechanism to make or break contacts for the protection of electrical appliances.

Electrical outlets are an essential part of any home as well as commercial buildings and industrial areas. Improper configurations of plugs and receptacles could result in serious electrical hazards, such as short circuit, electrocution, electrical fires and so on. Therefore, it’s important to select the right outlets for any space that involves electricity. There are a variety of factors that should be taken into consideration when choosing and ideal locking plug or connector for any of your needs.

The water pressure regulator reduces the water pressure by the local resistance of the flow channel in the valve to the water flow. The principle of constant ratio decompression is controlled by the water pressure ratio of the floating piston in the valve body, and the decompression ratio at the inlet and outlet is inversely proportional to the area ratio of the piston at the inlet and outlet.

The full name of tantalum capacitor is tantalum electrolytic capacitor, which is a kind of electrolytic capacitor. It uses tantalum metal as the medium instead of electrolyte as common electrolytic capacitor. In this article, we will introduce what tantalum capacitor is, what advantages tantalum electrolytic capacitor has, and the comparison with ceramic capacitor. Tantalum electrolytic capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal that acts as an anode, covered with an oxide that acts as a dielectric, and surrounded by a conductive cathode.

Compared with general-purpose reducers, precision reducers for industrial robots require short drive chains, small size, high power, light mass and easy control. A large number of reducers used in articulated robots are mainly RV reducers and harmonic drive gearboxes.

Nowadays, with the development of economy and society and the improvement of science and technology level, electrolytic capacitors and tantalum capacitors have become more and more popular in the daily life of ordinary people, and they are inside the lamps. But at the same time, many people do not understand the difference between them, and even confuse them. So, let's take a look at the difference between tantalum capacitors and electrolytic capacitors today.
