What are the types of pressure sensor?
A pressure sensor can feel the pressure signal, and by a certain law will be converted to the pressure signal available output of the electrical signal device or device.       Pressure sensors are usually composed of pressure-sensitive components and signal-processing units. According to different types of test pressure, pressure sensors can be divided into gauge pressure sensors, absolute pressure sensors, and differential pressure sensors.         Pressure sensors are the most commonly used in industrial practice of a sensor, which is widely used in a variety of industrial automation environments, involving water conservancy and hydropower, railroad transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines, and many other industries.         Common Units of Pressure   Europe the United States and other countries are accustomed to using psi as the unit PSI English full name Pounds per square inch, is “pound-force / square inch”. 1bar≈14.5psi1psi=6.894757kPa=0.0689476barIn China, we generally describe the pressure of the gas with “kilograms” (rather than “pounds”), the unit is In China, we generally describe the pressure of a gas as “kg” (instead of “jin”), and the unit is “kgf/cm2”, which means “kilogram-force per square centimeter”. In addition, there are Pa (Pascal, a Newton acting on a square meter), kPa, MPa, bar, millimeters of water, millimeters of mercury, and other units of pressure.     Five types of pressure sensors   ◆Strain Gauge Pressure Sensor-High Precision Most Widely Used        The core of the resistance strain gauge pressure sensor is a resistance strain gauge, which is a metal sheet that deforms when it is subjected to a force. When the strain gauge is subjected to an external force, its length and cross-sectional area change, which in turn changes the resistance value.         Strain sensors can measure physical quantities such as strain stress, bending moment, torque, acceleration, displacement, etc. and are most widely used in different fields. They are especially used in industrial weighing system products that require high accuracy, such as platform scales and hopper weighing systems.   ◆Ceramic Pressure Sensor-Resistant to Wear and Stability           Ceramic is the ideal material for pressure sensors because of its elasticity, impact resistance, abrasion resistance, and stable performance. Ceramic pressure sensors do not have liquid transfer, but use ceramic directly as the sensing diaphragm, so that the pressure indirectly on the back of the ceramic diaphragm of the thick film resistance, connected to a Wheatstone bridge, resistance resistance changes through the bridge to produce a voltage signal proportional to the pressure, the excitation voltage.     Compared with metal strain gauges, ceramic pressure sensors, ' biggest feature is corrosion resistance, in the measurement of corrosive media pressure, such as in the chemical industry, refrigeration and other fields are often very useful. Secondly, ceramic pressure sensors are often composed of a layered structure, so they have a better resistance to pressure peaks, but the corresponding sensitivity may not be as good as the former performance.   ◆Diffuse Silicon Pressure Sensors - Small Size, Big Signal           The principle is that the pressure of the measured medium acts directly on the diaphragm of the sensor, causing the diaphragm to produce a micro-displacement proportional to the medium pressure, so that the sensor's resistance changes, and rely on the electronic circuit to detect the changes, and quickly convert and output the corresponding standard measurement signal.         A significant advantage of diffusion silicon pressure sensors is a large signal output, for the back-end variable transmission conditioning line provides a great advantage, coupled with high resolution, high sensitivity, and its optional back-end circuit. Secondly, the compact size of diffusive silicon facilitates installation and can be widely used in medical devices to assist in biomonitoring.   ◆Sapphire Pressure Sensor - Accurate and Highly Priced           Similar to the first strain-resistor type, the receiving diaphragm deforms after being subjected to transmitted pressure, and after the change is sensed by the silicon-sapphire sensitive element, the bridge outputs an electrical signal that is proportional to the change in pressure.         As a semiconductor-sensitive element, sapphire's metrological properties are unrivaled, not only will not occur hysteresis, fatigue, and creep phenomena, but also under very high hardness is not afraid of deformation. In addition, sapphire has very good elasticity and insulating properties, such sensors can work in a variety of extreme environments with high reliability, good accuracy, and very small temperature errors.

What is wind sensor and how wind sensor works
What is wind sensor and how wind sensor works
What is wind sensor and how wind sensor works?      The wind speed sensor is a professional meteorological instrument used to measure the horizontal speed of wind. It uses a traditional three wind cups wind speed sensor structure that is highly durable.     In addition, thanks to its smooth bearing system, it starts smoothly and ensures accurate data collection. The built-in signal processing unit in the cup can output the corresponding wind speed signal according to the user's demand, which can be widely used in the fields of meteorology, ocean, environment, airport, harbor, laboratory, industry and agriculture, and transportation.       What is a Wind Speed Sensor?     wind speed sensors are devices designed to continually gauge both wind speed and wind volume (calculated as wind speed multiplied by the cross-sectional area). A prevalent type of wind speed sensor is the wind cup anemometer, believed to have been initially developed by Robinson. The measurement component consists of three or four hemispherical wind cups, evenly arranged and affixed in one direction on a rotating support fixed vertically to the ground.           What is a Wind Direction Sensor?     Wind direction sensors are engineered instruments that determine the direction from which the wind is blowing. Utilizing technologies such as vane sensors and windsocks, they provide essential data for applications like weather forecasting and aviation.     How Does a Wind Speed Sensor Work?     Wind speed sensors operate on principles such as cup anemometry. Picture small cups exposed to the wind—when they rotate, the sensor measures the rotational speed. This speed is then converted into electrical signals, offering accurate wind speed measurements.     The wind speed sensor is a professional meteorological instrument used to measure the horizontal speed of wind. It uses a traditional three wind cups wind speed sensor structure that is highly durable. In addition, thanks to its smooth bearing system, it starts smoothly and ensures accurate data collection. The built-in signal processing unit in the cup can output the corresponding wind speed signal according to the user's demand, which can be widely used in the fields of meteorology, ocean, environment, airport, harbor, laboratory, industry and agriculture, and transportation.   How Does a Wind Direction Sensor Work?     Wind direction sensors, often using vane technology, determine wind direction by measuring the orientation of a vane in relation to the incoming wind. This angular information is then translated into accurate directional data.       The wind direction sensor detects and senses the wind direction information of the outside world by the rotation of the wind direction arrow, and transmits it to the coaxial code disk, and outputs a physical device corresponding to the wind direction related value; its main body adopts the mechanical structure of the wind vane, and when the wind blows towards the tail of the wind vane, the arrow of the wind vane will point to the direction of the wind blowing over. In order to maintain sensitivity to direction, different internal mechanisms are also used to give direction to the wind speed sensor.     How Does an Ultrasonic Wind Speed and Direction Sensor Work?     The working principle of ultrasonic wind speed and direction sensor is to utilize ultrasonic time difference method to realize the measurement of wind speed and direction. As the sound propagation speed in the air, will be superimposed with the airflow speed in the direction of the wind. If the propagation direction of ultrasound is the same as the wind direction, then its speed will be accelerated; on the contrary, if the propagation direction of ultrasound if the opposite direction of the wind, then its speed will be slowed down. Therefore, under fixed detection conditions, the speed of ultrasonic wave propagation in the air can correspond to the wind speed function. The precise wind speed and direction can be obtained by calculation. Since the speed of the sound wave propagating in the air is greatly affected by the temperature; the wind speed sensor detects two opposite directions on two channels, so the effect of temperature on the speed of the sound wave is negligible.   Advantages:   Precision: Ultrasonic wind sensors provide highly accurate wind speed and direction measurements, minimizing errors in data collection.   Durability: With no moving parts, ultrasonic sensors experience less wear and tear, resulting in a longer lifespan.   Low Maintenance: The absence of mechanical components reduces maintenance needs, making ultrasonic sensors a cost-effective choice.       How to Install Wind Speed Sensors and Tips?     Adopt flange mounting, threaded flange connection to make the wind speed sensor lower fittings firmly fixed in the flange, chassis Ø65mm, in the circumference of Ø47.1mm open four are Ø6mm mounting holes, the u

There are so many different types of pressure sensors on the market today that it may take some time to figure out their differences.Nonetheless, sensors can be categorized to a large extent according to their type of pressure measurement, the sensing principle used the output signal and the measurement medium.         3 Types of Pressure Sensors and Applications   Below we will briefly describe the different types of pressure sensors to help you understand your options. Pressure sensors can be categorized into three main modes of measurement:There are various types of pressure sensors, but the main categories are: absolute pressure sensors, gauge pressure sensors and differential pressure sensors, each designed for a specific application. Before you choose the right sensor, you should understand each sensor type and the scenario in which it is applied. It is vital that you choose the correct type of pressure sensor for your application. Ignoring this can lead to measurement errors and system performance failures. In the following article, we will briefly introduce the three pressure sensor types and relate some common application examples to each.     1. Gauge Pressure   Measured with reference to atmospheric pressure (usually 14.7 PSI). Gauge pressure to atmospheric pressure as a reference fluid indicator pressure, can be measured by a pressure sensor, called gauge pressure, that is: absolute pressure - atmospheric pressure = gauge pressure. Gauge pressure in the vacuum industry specifically refers to: the value of the relative pressure of the gas measured with an ordinary vacuum gauge (relative pressure gauge), expressed as a negative number, refers to the difference between the pressure of the gas being measured and the atmospheric pressure. Also called negative pressure. When higher than atmospheric pressure, you will show a "positive" pressure; when lower than atmospheric pressure, you will show a "negative" pressure.     2. Absolute pressure In short, this is the pressure measured relative to an absolute vacuum. The absolute pressure of a complete vacuum is zero PSI and increases from there. Absolute pressure is pressure relative to zero pressure. Correspondingly, Gauge Pressure (Relative Pressure) : If the difference between Absolute Pressure and Atmospheric Pressure is a positive value, then this positive value is the Gauge Pressure . For example, we are in the environment for a standard atmospheric pressure, then the absolute pressure is 1 atm, gauge pressure is 0 Pa. That is, gauge pressure = absolute pressure - atmospheric pressure > 0. If it is less than 0, it is called vacuum. Absolute pressure PaA, gauge pressure PaG. If you need to read pressure below atmospheric pressure, you can use this type of sensor.     3. "Differential pressure". It's exactly what it sounds like, the difference between two pressures, the pressure being measured and the reference pressure.     Application Scenarios   There are many types of pressure sensors, but they fall into one of these three main categories: absolute pressure sensors, gauge pressure sensors, and differential pressure sensors, each designed for a specific application. Here are some typical applications for each type.       A.Absolute pressure sensors:   Weather forecasting: Absolute pressure sensors are used in weather stations and meteorological instruments to measure atmospheric pressure, which is critical for weather forecasting. Vacuum Systems: Absolute pressure sensors are used in vacuum systems to monitor and control vacuum levels in applications such as semiconductor manufacturing and vacuum packaging.
