    5 Common Problems With Pressure Sensor

    Pressure sensors today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration. In the following, ATO industrial automation will introduce some of the common problems with the pressure sensors.

    How to Maintain Pressure Sensor?

    Pressure sensor is a device or device that can feel pressure signal and convert it into usable output electrical signal according to certain rules. Pressure sensor usually consists of pressure sensor and signal processing unit. In addition to understanding the basic information of some pressure sensors, we should also know how to maintain and pay attention to some key points in use. In this article, ATO industrial automation will give you a detailed introduction.

    Difference between Pressure Sensor and Pressure Transmitter

    Many items have several names, and many of them are very similar, such as grapes and raisins, oranges and oranges, cherries and cherries. They are very similar in appearance but they are not the same item. There are also the same situation in the industrial instrument industry. Although pressure transmitters and pressure sensors have similar names, they are indeed two completely different types of accessories. Their differences are mainly reflected in the following aspects. The ATO will provide you with detailed description on their differences.

    Pressure Sensor Application in HVAC System

    Pressure sensors are an integral part of most heating, ventilation, air conditioning and refrigeration systems. Not only can it help maintain a comfortable indoor environment, it can also integrate HVAC systems with building automation systems to improve system operation efficiency.

    Why does the Pressure Sensor Make Noise?

    A pressure sensor is a device equipped with a pressure-sensitive element that measures the pressure of a gas or a liquid against a diaphragm made of stainless steel, silicon, etc. When using a pressure sensor, there will inevitably be some problems, such as noise. What are the reasons for the noise? It may be caused by the discontinuity of the internal conductive particles, or the shot noise generated by the semiconductor device, etc. Some other reasons will be introduced in detail below.

    Why Calibrate Pressure Sensor?

    A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal. Before using pressure sensors for measurement work, we need to perform detailed calibration work on them, because if we do not calibrate them before use, various faults or inaccurate measurement results may occur during the measurement process.

    What Factors Affect the Stability of Pressure Sensor?

    Pressure sensors are one of the most commonly used sensors in industrial practice and are widely used in a variety of industrial automation environments and many other industries. When purchasing a pressure sensor, the stability of the product is a major consideration. What are the factors that affect the stability of pressure sensors? Next, we will detail the factors that affect the stability of pressure sensors.

    How to Keep the Sensing Diaphragm's Performance of Pressure Sensor?

    As with all continuous output pressure sensors, regardless of the application, the most sensitive component to the sensing diaphragm and most critical to the function of the pressure sensor is the sensing diaphragm. If it doesn't work, your readings will be incorrect, or in extreme cases, you will have no readings at all. 

    5 Tips for Using Pressure Sensors

    Pressure sensor is a device that converts non-electricity into electrical signals. In modern industrial equipment, pressure sensors are an indispensable part of the reason. It can also be seen from the two aspects. Traditional industrial equipment, such as in its The necessary sensors are added to the device and equipped with precision measuring components, its function and accuracy can be improved; industrial equipment is used as the control object of the automation system or as the automation system. A part of the system must be compatible with the three parts of the automation system (detection, control, and execution) or provide interfaces to integrate them into an organic whole. To sum up, adding sensors as industrial equipment itself is a necessary condition for the replacement of traditional equipment displacement sensors.

    How to Choose a Pressure Sensor?

    For most engineering applications, choosing a suitable pressure sensor will have an important impact on the accuracy of the entire engineering measurement and the progress of the project. There are many types of pressure sensors available today. How to select a pressure sensor reasonably according to the specific measurement purpose, measurement object and measurement environment is the first problem to be solved when measuring a certain quantity.

    How to Control the Temperature Drift of Pressure Sensor?

    Pressure sensor is a device that senses a pressure signal and converts the pressure signal into a usable output electrical signal. Under the interference of external factors, the output of the sensor usually has unneeded changes that have nothing to do with the input. This type of change is called "temperature drift", and the main reason for drift is that the sensitive components of the measurement system are usually easily interfered by external temperature, humidity, electromagnetic interference and sensor conditioning circuits.

    What are the Types of Pressure Sensors?

    Devices that can measure pressure and provide remote electrical signals are collectively referred to as pressure sensors. The pressure sensor is an important part of the pressure detection instrument, and its structure is varied, the common types are strain type, piezoresistive type, capacitive type, piezoelectric type, vibration frequency pressure sensor and so on. In addition, there are photoelectric, optical fiber, ultrasonic pressure sensors and so on. The pressure sensor can directly convert the measured pressure into various forms of electrical signals, which is convenient to meet the requirements of centralized detection and control of the automation system, so it is widely used in industrial production.

    What is a Pressure Sensor?

    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. 

    How to Install a Constant Pressure Water Pump?

    The working principle of the constant pressure water pump is as follows:

    1. The VFD drives the water pump, and the pressure sensor/transmitter feeds back the pressure signal to the VFD to form a closed loop system.
    2. When the water pipe pressure is less than the set value, the VFD wakes up and starts pumping water.
    3. When the pressure does not reach the set target, the operating frequency will continue to increase to the rated frequency of the pump.
    4. When the pressure is greater than the set pressure, the operating frequency will decrease.
    5. When the pressure is greater than the sleep pressure, the frequency decreases to the sleep frequency for a period of time, and then stops pumping water.
    6. When the pressure is lower than the wake-up pressure, the pump starts to run again.
    How to Install and Wire Pressure Sensor Safely?

    A pressure sensor is a device that can sense the pressure signal and convert the pressure signal into a usable output electrical signal according to a certain law. It usually consists of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. ATO pressure sensor is the most commonly used sensor in the industry. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electricity, ships, machine tools, pipeline and many other industries.
