    Photoelectric Sensor Working Principle

    Photoelectric sensor is a general term for sensors that use light to detect objects. It is a device that emits light signals from the emitting part of the sensor and is reflected, blocked and absorbed by the detected object, and then detected by the receiving part and converted into corresponding electrical signals to achieve control. The photoelectric sensor consists of three parts, including transmitter, receiver and detection circuit.

    Colorimeter is also called the color meter, it is a kind of measuring instrument for material color characteristics, colorimeter is primarily used to measured the color of the material, color, color value measurement and analysis, if the colorimeter machine with computer, can improve the ability of analysis and processing of color, and the user can according to need to color from computer storage in the library to find out all kinds of data for color matching. In this article, we will introduce some basic about colorimeter.

    Thermal Overload Relay Basics

    Thermal overload relays are overload relays that apply the principle of current thermal effect and use electrical thermal bimetallic sheets as sensitive components. The electrical thermal bimetal sheet is made by heating and rolling two alloys with large difference in linear expansion coefficient. When heated, the bimetallic sheet bends from the high expansion layer to the low expansion layer. When the current is too large, the element acts due to "heat", so that its linked moving contact cuts off the power supply of the controlled circuit and the protected equipment.

    Diaphragm Pump Basics

    The Diaphragm pump, also known as control pump, is the main type of actuator. It changes the fluid flow with the help of power operation by receiving the control signal output by the adjustment control unit. The function of the diaphragm pump in the control process is to accept the control signal of the regulator or computer, change the flow rate of the adjusted medium, and maintain the adjusted parameters within the required range, so as to achieve the automation of the production process.

    Float Switch Basics

    The liquid level float switch is a liquid level control part with a simple structure and convenient use. It is equipped with a complex circuit and will not be disturbed. As long as the material is selected correctly, any liquid, pressure and temperature can be used. The float switch uses magnetic operation, no mechanical connection, simple and reliable operation. It has been widely used in the shipbuilding industry, generator equipment, petrochemical industry, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. When the float switch is floated by the measured medium, the float drives the main body to move, and the magnet at the other end of the float will control the magnet on the switch action lever.

    Carbon Dioxide Sensor Basics: Working Principle, Maintenance and Advantages

    A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO2 sensors are infrared gas sensors (NDIR) and chemical gas sensors.

    Angle Seat Valve Basics: Components, Working Principle and Application

    Angle seat valves are 2-way, 2-position pneumatic piston valves. The piston pneumatic actuator provides linear motion to lift the seal from its seat. Because the seat is positioned at an angle, flow obstruction is minimal in the open position, resulting in excellent flow and low pressure losses. They are used to regulate the flow of liquids, gases, vapors, vacuum and even corrosive fluids. Angle seat valves can operate in high temperature and high viscosity media even at zero differential pressure. Rugged design makes these angle seat valves a best choice for harsh applications, and they have a very high cycle life.

    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.

    Wind Meter Basics & Working Principle

    The wind meter (anemometer) is an instrument that measures the speed of wind. To determine wind speed, wind meters detect changes in certain physical properties of the fluid or the effect of the fluid on a mechanical device inserted into the airflow. There are many types of it. The most commonly used in meteorological stations is the wind cup anemometer. Its sensing part consists of three parabolic cone empty cups fixed on the bracket at 120°to each other. The concave surfaces of the empty cups are all in one direction. The entire induction part is installed on a vertical rotating shaft. Under the action of wind, the wind cup rotates around the shaft at speed proportional to the wind speed.
