Abstract: Beijing Tiankang_What are the solutions to sensor drift? The excellent flowmeter and flowmeter manufacturers and quotation manufacturers provide you with information. What are the solutions to sensor drift? Sensor is a commonly used detection device, which is widely used in many industries. As long as electronic components are subject to drift, sensors are no exception. There are two types of sensor drift. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. What are the solutions to sensor drift? Sensor is a commonly used detection device, which is widely used in many industries. As long as electronic components are subject to drift, sensors are no exception. There are two types of sensor drift: zero point drift and temperature drift. These two drifts have a great influence on the measurement accuracy of the sensor. So how can we solve these problems? The following will give you a detailed introduction to the methods to solve the sensor drift. There are many reasons for sensor zero to drift. For example, for the pressure sensor, the parameters of the components in the bridge circuit are asymmetric; the temperature coefficient and linear expansion coefficient of the sensitive grid material of the elastic element and the resistance strain gauge are different, and the lengths of the bridge leads are inconsistent, which eventually lead to the sensor forming a bridge The overall temperature coefficient of the rear adjacent arms has a certain difference. When the temperature changes, the resistance changes of the adjacent arms are different, so that the output of the bridge is unbalanced, that is, zero drift occurs; for smart sensors, the time drift——That is to say, for the system, with the increase of time, it is equivalent to aging the system, so that the structural characteristics of the system will change, resulting in drift. Warm drift——Instability of the zero point caused by the influence of temperature. It can be seen that the influence of temperature is the most important factor that produces zero drift, and it is also the most difficult to control. There are generally two ways to solve temperature drift, hardware and software. For the pressure sensor, the hardware methods include the appropriate constant resistance method in series and parallel on the bridge arm, the bridge arm thermistor compensation method, the bridge external series and parallel thermistor compensation method, the double bridge compensation technology, the triode compensation technology, etc. . The software method is to eliminate the offset through the software program. This method is very practical for the sensor with digital output. The customer can implement it through software programming, or when the sensor is equipped with a digital display meter, it can also be realized by adjusting the digital display meter. All are very convenient. Under the highly developed form of modern science and technology, the requirements for the accuracy of measurement are getting higher and higher, so it is particularly important to reduce or eliminate the sensor error caused by temperature. When the customer finds that the sensor has drift, the manufacturer needs to request the sensor to provide a solution to solve the drift. The above is the whole content of this article.
