If a very thin metal film instead of a metal wire, which is called a hot-film anemometer. The function is similar to that of a hot wire but is mostly used to measure the flow rate of liquids. 

    Electrolytic Capacitor Basics: Features, Functions and Advantages

    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) that is close to the positive electrode is the dielectric, and the cathode is made of conductive material, electrolyte (the electrolyte can be liquid or Solid) and other materials together, because the electrolyte is the main part of the cathode, so the electrolytic capacitor is named. At the same time, the positive and negative electrolytic capacitors should not be wrongly connected.

    Explosion Proof Motor Bascis: Working Principe, Overhaul and Maintenance

    Explosion-proof motor is a kind of motor that can be used in flammable and explosive factories, and does not generate electric sparks during operation. In a very short period of time, a large amount of energy is released, high temperature is generated, and a large amount of gas is released, causing a high-pressure chemical reaction in the surrounding medium.

    Automatic Transfer Switch Basics: Funtions, Advantages and Selecting Principle

    An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source. The auto transfer switch has advantages of simple structure, easy & reliable operation, no noise, small impact, and long service life. Auto changeover switch is suitable for the illuminating circuits of commercial buildings, shopping mall, banks, and high-rise buildings where the power supply can not be cut off for a long time.

    Centrifugal Pump: Working Principle, Advantages, Maintenance and Application

    A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller's vane tips.

    Induction Motor: Working Principle, Features and Advantages

    An induction motor refers to an AC motor that relies on electromagnetic induction between the stator and the rotor to induce a current in the rotor to realize electromechanical energy conversion. The stator of the induction motor consists of three parts: the stator core, the stator winding and the frame. Under normal circumstances, the rotor speed of the induction motor is always slightly lower or slightly higher than the speed of the rotating magnetic field, so it is also called an "asynchronous motor".

    The electrical measuring instrument in the pressure measuring instrument is usually called a pressure transducer (pressuretransducer). It is a sensor that converts the pressure signal into a voltage signal output. Usually the pressure sensor is generally composed of elastic sensing element and displacement sensing element. The function of the elastic sensing element is to make the measured pressure act on a certain area and convert it into displacement or strain, and then the displacement sensing element or strain gauge converts it into an electrical signal that has a certain relationship with the pressure. Sometimes the functions of these two elements are combined.
