| Pressure controller is the most commonly used controller in industrial practice, which is widely used in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, power, ships, machine tools, pipelines, and many other industries. Below is a brief introduction to the principles and applications of some commonly used sensors. There is also a medical pressure controller. The following are some commonly used technical terms for pressure controllers. 1. Sensitivity The sensitivity of the pressure controller is directional. When the measured quantity is unidirectional and requires high directionality, sensors with low sensitivity in other directions should be selected; If the measured vector is a multidimensional vector, the smaller the cross sensitivity of the pressure controller, the better. 2. Frequency response characteristics The frequency response characteristics of the pressure controller determine the frequency range to be measured, and it is necessary to maintain undistorted measurement conditions within the allowable frequency range. In fact, the response of the pressure controller always has a certain delay, and it is hoped that the shorter the delay time, the better. 3. Linear range The linear range of a pressure controller refers to the range where the output is proportional to the input. In theory, within this range, the sensitivity remains constant. The wider the linear range of the pressure controller, the larger its range and can ensure a certain measurement accuracy. When selecting a pressure controller, the first thing to consider when determining the type of pressure controller is whether its range meets the requirements. 4. Stability The stability of the pressure controller has quantitative indicators. After exceeding the service life, it should be recalibrated before use to determine whether the performance of the pressure controller has changed. 5. Accuracy Accuracy is an important performance indicator of pressure controllers, which is an important link related to the measurement accuracy of the entire measurement system. The higher the accuracy of the pressure controller, the more expensive its price is. Therefore, the accuracy of the pressure controller can only meet the accuracy requirements of the entire measurement system, and there is no need to choose too high. This allows for the selection of cheaper and simpler pressure controllers among many that meet the same measurement purpose. |
