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. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.
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 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 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.
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.
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.
As the name implies, hub motors place the electric motor in the front or rear wheel hub to help you move the bicycle down the road. A mid-motor puts an electric motor and gears right on the pedal shaft and boosts your pedal power directly, transmitting it through a chain or belt to the rear wheel.
A brushed DC electric motor is a rotating electrical machine containing a brush device that converts electrical energy into mechanical energy or converts mechanical energy into electrical energy. The brush DC motor is the basis of all motors. It has the characteristics of fast starting, timely braking, smooth speed regulation in a wide range, and simple circuit control.
Hydraulic hand pumps play an important role in every industry that requires testing and calibration of pressure instruments such as pressure transmitters, gauges and switches. From energy production and healthcare to construction and wastewater management, they perform a very necessary function that ultimately helps keep our global economy running safely and efficiently. With such a wide range of uses, there isn't one hydraulic hand pump can meet the needs of all applications. So, in this article we'll learn about the basic functions of a hydraulic hand pump and outline some of its most important features.
The output waveform of the pure sine wave power inverter is good, the distortion is very low, and its output waveform is basically consistent with the AC waveform of the mains grid. In fact, a good pure sine wave inverter provides a higher quality AC power than the grid. Pure sine wave inverter has little interference to radio, communication equipment and precision equipment, low noise and strong load adaptability. It has high efficiency and can meet all AC load applications.
ATO pneumatic grease pump is a kind of refueling equipment, which is widely used at present. It can replace oil in time for automobile maintenance and various mechanical equipment. The pneumatic grease pump with 3 gal~12 gal is the most powerful assistant in production and life. It is a kind of pneumatic tool.
Laser sensors utilize laser technology to measure. It consists of a laser, a laser detector and a measuring circuit. Laser sensor is a new type of measuring instrument. Its advantages are fast speed, high precision, large range, strong anti-light and electrical interference ability, etc. And it can realize non-contact long-distance measurement.
Sound level meter is the most basic instrument in noise measurement. The sound level meter is generally composed of a condenser microphone, a preamplifier, an attenuator, an amplifier, a frequency weighting network, and an RMS indicator. The working principle of the sound level meter is: the microphone converts the sound into an electrical signal, and then the preamplifier transforms the impedance to match the microphone and the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting on the signal (or external filter), and then amplifies the signal to a certain amplitude through the attenuator and amplifier, and sends it to the rms detector (or external power supply). flat recorder), the value of the noise sound level is given on the indicator head.
Water is one of the important environmental factors and an important component of the human body. The body water content of man accounts for about 65% of body weight, and the daily physiological water requirement of each person is about 2 to 3 liters. All physiological activities of the human body, such as thermoregulation, nutrient delivery, waste excretion, etc., require water to complete. Therefore, it is essential to measure water quality.
Relays are an electronic control device with a control system (that is, an input loop) and a controlled system (output loop), and are usually used in automated control circuits. The relay is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of conversion circuit, automatic adjustment and safety protection in the circuit.

Today, we are going to introduce gear pump to you. Gear pump is applied in industrial widely, if you have a general idea about gear pump, it will help you a lot in you work.
The gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or pressurize it. Two closed spaces are composed of two gears, pump body and front and rear covers. When the gear rotates, the volume of the space on the disengagement side of the gear increases from small to large, forming a vacuum. After the liquid is sucked in, the volume of the space on the meshing side of the gear changes from large to small, and the liquid is squeezed into the pipeline. The suction cavity and the discharge cavity are separated by the meshing line of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the pump outlet.
