What Types in Pressure Sensor Measurement Method
There are 10 types of measurement methods for pressure sensors under most application conditions. The method used for the pressure sensor in measurement is very important to the entire inspection system, which will directly affect whether the measurement task can be completed successfully. In this regard, it is necessary to analyze the different measurement purposes and specific conditions to find a practical way.
According to measuring means, measurement methods of pressure sensors are classified into direct measurement, indirect measurement, and combined measurement. According to measuring ways, it can be divided into minor- difference measurement, deviation measurement and zero position measurement. According to measuring accuracy, there are equal accuracy measurement and non-equal accuracy measurement. According to pressure change, there are dynamic measurement and static measurement. According to whether the sensitive component is in contact with the measured medium, there are contact measurement and non-contact measurement.
I. According to measuring means
Compared with direct measurement, indirect measurement requires much measured quality, and the calculation process is complicated so the factors causing errors are more. However, if we analyze the error as well as select and determine the optimized measurement method, then perform the indirect measurement under ideal conditions. The accuracy of the measurement result is not necessarily low, and sometimes a high measurement accuracy will also be obtained. Indirect measurement is generally used in situations where it is inconvenient to measure directly or lack direct measuring means.
