  • Classification of sensors into electronic

    2017-10-11

    The sensor is a detection device, can feel the measured information, and can detect the sensed information, according to the law must transform into electrical signals or other information in the form of output required to meet the information transmission, processing, storage, display, record and control requirements. It is the most important link for realizing automatic detection and automatic control. The national standard GB7665-87 sensor is defined as: "feelings can be measured under the law and in accordance with a certain signal can be converted into the device or device, usually consisting of sensitive components and conversion components".

  • What is capacitance and its classification?

    2017-11-10

    The so-called capacitor, is to accommodate and release the electronic components of charge. The basic working principle of the capacitor is charging discharge, of course, rectification, oscillation and other functions. In addition the capacitor has the advantages of simple structure, mainly consisting of two electrodes and caught in the middle of the insulating medium, so the capacitor type is mainly decided by the electrode and the insulating medium.

  • Instructions on the use of switching power supply

    2017-09-26

    With the rapid development of power electronics and switching power electronic equipment industry, the relationship with the people's work and life increasingly close, and electronic equipment cannot do without reliable power supply, computer power supply in 80s the full realization of the switching power supply, the completion of the first computer power generation in 90s, have entered the field of electronic switching power supply, electrical equipment, program-controlled switches, communication, power supply, electronic testing equipment control equipment power supply has been widely used in switching power supply

  • Design of single chip switching power supply

    2017-08-01

    Switching power supply with high efficiency, light weight, small volume, wide range of advantages, from the middle of twentieth Century since the advent of extremely rapid development, has been widely used in computer, communication, aerospace, office and household appliances, is to replace the linear regulated power supply potential.

  • Basic knowledge of electronic components

    2017-07-29

    On the most basic electronic components is hindering the flow of current. Two of the most basic parameters to measure the resistor is resistance and power. Used to express the blocking effect of resistance resistor current, ohm. In addition to the basic unit, as well as kilohms and megohm. Used to indicate the maximum power current resistor can bear, Watt said, 1/16W, 1/8W, 1/4W, 1/2W, 1W, 2W etc, more than this maximum value, it will burn out resistor.

  • Definition and application of microswitch

    2017-06-20

    Micro switch is a kind of quick switch with pressure and actuation. It is also called sensitive switch. Master electrical instantaneous a trip is very small, the micro switch contact switch is small. The hand gently touched on, factories used to switch the internal short circuit, over-current protection. When the external mechanical force on the operation button, the operation button will move downward, through the pull hook. When the spring is pulled to a certain length, the moving spring rapid downward movement of the moving contact reed to the right end of the normally open contact contact with the following, in order to achieve the conversion circuit. If the external force is removed, the contact will be instantaneously converted under the action of spring restoring force.

  • The working principle of the thermostat

    2017-04-18

    The temperature controller is made according to the principle of thermal expansion and contraction of objects. Thermal expansion and contraction are common properties of objects, but the degree of thermal expansion and contraction of different objects is different.
