Push button switch is pressed that action, release that reset is used to connect and break small current circuit electrical appliances, simple structure, the application is very wide. It uses the button to push the transmission mechanism, so that the dynamic contact and static contact press through or break and achieve circuit switching.

Push button switch refers to a switch that uses a button to push the transmission mechanism, presses or disconnects the moving contact and the static contact, and realizes the circuit switching. It is a kind of electrical appliances with simple structure, composed of a metal shell and a circuit, in the electrical automatic control circuit, it is used to manually send out control signals to control contactors, relays, electromagnetic starters, etc. The working principle of the button: after the power is turned on, it outputs a high level signal, when the button is pressed, the button outputs a low-level signal in the normal state.

When a short circuit occurs in the power system, a large short-circuit current will be generated. If not limited, it is very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, in order to meet the requirements of breaking capacity of some circuit breakers, reactors are often connected in series at the outgoing circuit breaker to increase the short-circuit impedance and limit the short-circuit current. Due to the use of reactor, the voltage drop on the reactor is large in case of short circuit, so it also plays a role in maintaining the bus voltage level. It makes the voltage fluctuation on the bus less and ensures the operation stability of user electrical equipment on the non fault line. This is how the reactor works.

The operating principle of the AC spindle servo motor is that when the symmetrical three-phase winding on the stator is connected to the symmetrical three-phase, the excitation current is supplied by the power supply and a rotating magnetic field is established in the air gap between the stator and the rotor rotating at a synchronous speed. By the electromagnetic inductance, the induced potential is generated in the rotor guide bar. Because the rotor guide strip has formed a closed circuit, a current is running through the rotor guide strip. This generates electromagnetic torque and realizes the energy transformation from electrical energy to mechanical energy. ATO provides customers with a wide range of AC spindle servo motors of good quality with favorable prices.

The application of sensors involves machinery manufacturing, industrial process control, automotive electronics, communication electronics, consumer electronics and special equipment. There are various kinds of voltage sensors, and based on the measuring principle can be divided into Hall voltage sensors, photoelectric isolated voltage sensors, electrically isolated voltage sensors, voltage transformers and so on. Voltage sensors are able to sense the measured voltage and convert it into a usable output signal. In a variety of automatic detection and control systems, voltage sensors often track and collect AC and DC voltage signals that change at high speed. The signals may be high voltage, high current, or weak power with poor load capacity.  In these cases, it is necessary to use suitable voltage sensors to collect voltage signals that cannot be directly measured or mismatched, so as to obtain standardized and electrically isolated voltage signals. ATO offers a full range of voltage sensors with different measuring ranges at favorable prices.

The meter directly outputs thyristor trigger signal, which can drive all kinds of thyristor loads. It is used in all kinds of high and low voltage switchgear, dry-type transformer, box type substation and other related temperature application fields. In addition to understanding what the temperature controller is, we also need to know its three "how": how to work, how to use, and how to choose the temperature controller for better use of ATO.   

Blower has a promising future in the global market. ATO regenerative blower is distinguished from ordinary air blowers by its design, in which the bearings are made of special high-temperature resistant bearings, which can withstand twice the temperature of ordinary fans. It has been there a sharp increase in demand in recent years. At present, the production of regenerative blower as well as technology has been quite mature, continuing to evolve and upgrade. Regenerative blower is capable of providing a great range of cfm and pressure. It is important to know the principle of operation. The impeller of a regenerative blower has multiple blades on the edge of the impeller, and as the impeller rotates, air goes through the inlet side of the blower as it reaches the impeller. It will actually accelerate around the outside and between each blade it will actually regenerate over the next blade until it reaches the total differential pressure at the discharge. Due to the energy of multiple blades of the high-pressure fan rotation, the wind pressure is quickly superimposed, and a high-pressure or high suction force is formed. It is a pretty efficient way to generate pressure.

Control transformers are compact dry-type transformers. It is often applied as a transformer for supplying power to machines, electrical machinery, relays, lighting, etc. As a power supply system for control circuits in electrical equipment. Control transformer is suitable for AC 50Hz/60Hz, voltage 1000V and the following power supply circuit, which can work continuously for a long time at rated value. Control transformers operate on the basic principle of the magnetic effect of current. Control transformer consists of transformer core and coil transmission line. It has two coils, the primary coil and the secondary coil.  The secondary coil is outside the primary coil. When the primary coil is connected to the AC current, the transformer core creates an alternating electromagnetic field and the secondary coil creates an induced current. It can not only change the voltage of the AC current, but also change the characteristic impedance. And it can change the flow of electricity without exceeding the output power of the design scheme. ATO offers more reliable control transformers at a more affordable price.

Torque sensors are divided into dynamic torque sensors and static torque sensors. The static torque sensor can also be called reaction torque sensor, while the dynamic torque sensor can also be called non-contact torque sensor or rotary torque sensor. Torque sensors are used for detecting the perception of torque on various rotating or non-rotating mechanical components. The torque sensor converts the physical changes of torsion into precise electrical signals. The torque sensor has the advantages of high precision, fast frequency response, good reliability and long life. ATO has many better torque sensors for sale.

Common torque sensors are measured using bonded strain gauge technology, where the strain gauge is bonded to a suitably designed shaft. It features a circular shaft and a strain gauge torque sensor for 45 degrees applications. This design has been around for years. However, the design and configuration of the device will be determined by the application, the shaft can be solid or hollow, and the cross section can be different from cross, square or other custom designs in order to obtain maximum signal output. Shear stress is caused when torsion is applied to an axis causing it to distort.
