We live in a world of sensors. They are everywhere. You can find them in our homes, offices, hospitals, etc. They can make our lives more convenient and easy by detecting our presence to turn on lights, regulate room temperature, detect smoke or fire, and many other tasks. In this article, ATO will make a detailed introduction from four aspects: the definition of sensor, different types, application and how to choose a right sensor.

There are many definitions of sensors. Generally speaking, a sensor is a detection device, which can sense the measured information, and can transform the perceived information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, record and control.

Gear motor is an integrated device of speed reducer and electric motor, also known as gear reduction motor. Professional manufacturers integrate and assemble the gearbox and electric motor to be a set for sale. Gear motor is a unit for connection, transmission, speed reduction, and increasing torque. AC/DC gear motors have the advantages of low energy consumption, superior performance, small size, compact structure, reliable and durable, etc.

According to speed, a motor itself can be divided into low speed (low rpm) motor and high speed (high rpm) motor. According to functions, there are drive motors and control motors. No matter what kind of motor, there is a rated speed and torque. To obtain variable speed, a dedicated controller or speed regulator is needed to control the speed, but this will increase a certain cost and cause the motor price to become higher. On the other hand, performance of the motor after speed regulation will decrease to varying degrees. In this case, gear motor can perfectly solve this problem.

What factors should be taken into consideration when selecting a hydraulic motor? The first thing that should be focused on is the operating conditions of the hydraulic system, following which we should decide on the output torque, speed and power as needed so as to pick a right product model and specification.

Hydraulic motors are rotary actuators that convert hydraulic pressure supplied by the hydraulic pump into mechanical energy (such as torque and speed) applied to its output shaft. Hydraulic motors can be classified in different ways. Based on different rated revolving speed, there are high-speed and low-speed motors. And in terms of configuration, there are mainly four types of hydraulic motors among others, namely, gear motors, vane motors, radial plunger motors and axial plunger motors.

The thyristor power controller adopts thyristor (SCR or TRIAC) as the switching component, namely, a non-contact switch that can quickly and accurately control the closing time. It serves as an essential terminal equipment for power control designed for high precision and high dynamic indicators. It is worth noting that different loads and constraints of the operation environment determine different control modes and require various supporting equipment. Among control modes there are phase angle control, distributed crossover and time proportional zero crossover. In actual use, SCR power controllers can be sorted into single-phase SCR power controllers and three-phase SCR power controllers in accordance with their load types, power supply types and power supply voltage levels. So, how should we choose the right type of power controller and bring its optimum performance into play with minimal damage? The following passages will give you the answer.

A power regulator is a panel-mounted power adjustment unit that uses a thyristor (also called Silicon Controlled Rectifier or SCR) and its trigger control circuit to adjust the load power. Thanks for its small size, high efficiency and durable service life, it is widely used in AC and DC motor speed control system, power control system, follow-up system, temperature control and many other sectors. SCR power regulator works by means of an intelligent digital control circuit. Its precise control of voltage, current and power makes for precise temperature control. And its advanced digital control algorithm greatly improves energy efficiency, which highlights its important role in saving electric energy. Power regulators are becoming an indispensable equipment in the automation industry.

Safety switch is a switch that prevents people from entering a dangerous area before all safety conditions are met. Also it is a device that monitors current in various applications. Safety switches can be used in major equipment applications (conveyor belts, production line equipment, heavy equipment) and electrical protection of whole system. The safety switch works by monitoring the current and detecting electrical faults, which means that in case of leakage, short circuit, overload, the safety switch will cut off the power supply of the faulty system almost immediately (within a few milliseconds).

The air blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and oil tank), drip nozzle. The blower operates eccentrically on the rotor offset in the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from returning. This type of air blower is also called a sliding vane blower. There are many types of air blowers, mainly divided into the following categories.

Bandwidth is one of the most important indexes of oscilloscope. The bandwidth of analog oscilloscope is a fixed value, while the bandwidth of digital oscilloscope has two kinds: analog bandwidth and digital real-time bandwidth. The maximum bandwidth that digital oscilloscope can achieve by using sequential sampling or random sampling technology for repeated signals is the digital real-time bandwidth of oscilloscope. The digital real-time bandwidth is related to the maximum digital frequency and waveform reconstruction technology factor K (digital real-time bandwidth = maximum digital rate / k), which is generally not directly given as an index. 

Vibration meter is an instrument used to measure the peak value, peak-to-peak value, average value or root mean square value of vibration such as velocity, acceleration and displacement. The vibration meter can be applied in mechanical manufacturing, electric metallurgy, general aviation etc. The main parts of this instrument are integral differential circuit, amplifying circuit, voltage detector and meter head. The integral differential circuit is used to complete the integral differential operation between the above vibration quantities. Generally, integral and differential operational amplifiers can be used, low-pass filters and high pass filters can also be used to complete integral differential operations. However, we should pay attention to this instrument's application frequency range when we are using it for calculation. The vibration meter can only obtain the total intensity (vibration level) of the vibration, but cannot obtain other information, so its scope of using is limited.
