For most engineering applications, the selection of the right pressure sensor will have a significant impact on the accuracy of the measurement and the progress of the project. Nowadays, there are many kinds of pressure sensors. How according to the specific purpose of measurement, measurement objects and measurement environment reasonable selection of pressure sensors, is in a certain amount of measurement when the first problem to be solved. First of all, clear pressure sensor measurement medium Food and pharmaceutical level of the measurement environment, need to pay attention to the measurement process of hygiene issues and the measurement medium is not intentionally corrosive, the most suitable for this condition is a flat film type pressure sensor. This pressure sensor diaphragm and shell material for the 316L stainless steel structure. Flat membrane type structure is also easy to clean. Like mud, crude oil, wet soil and other particles, impact, viscous media pressure measurement, the pressure sensor shock resistance, vibration resistance, resistance to solid sand impact, wear resistance requirements are more stringent. Shock-resistant pressure sensors are preferred for such conditions. Second, to prejudge the maximum pressure value of the measurement Generally speaking, you need to choose a pressure sensor with a range of about 1.5 times larger than the maximum value. This is mainly because in many measurement conditions, such as the site environment is particularly complex and highly intrusive occasions. There are peaks and continuous irregular up and down fluctuations, such instantaneous peaks can destroy the pressure sensor, sustained high pressure values or slightly beyond the transmitter’s calibration of the maximum value will shorten the life of the sensor, or even cause damage to the sensor and burned out. Accurate prediction of the pressure range is very necessary. Third, the accuracy of the pressure sensor needs Accuracy is an important performance indicator of the pressure sensor, the accuracy of the pressure sensor is related to the accuracy of the entire measurement system is an important part. The higher the accuracy of the pressure sensor, the more expensive, so the accuracy of the pressure sensor as long as the accuracy requirements to meet the entire measurement system can be, do not have to choose too high. In this way, you can choose the cheaper and simpler sensors among the many sensors that fulfill the same measurement purpose.
