Principles for selecting differential pressure sensors
View：820 Release Date：2024/9/9 21:01:37
When choosing a differential pressure sensor, multiple key factors need to be considered to ensure that the sensor can meet specific application requirements. Here are some important considerations:
Measurement range: Select the appropriate measurement range based on actual measurement needs. The measurement range of differential pressure sensors is usually 0-2500Pa, but there are also special models with a wider measurement range to meet the needs of different applications.
Accuracy: Accuracy is an important indicator for measuring sensor performance. Choose the appropriate accuracy level according to actual needs, and in general, industrial production processes require an accuracy within ± 0.5%.
Stability: Stability is a key factor in measuring the long-term performance of sensors. When choosing, pay attention to its stability and choose model 1 that has been verified for a long time and has stable performance.
Installation method: Choose the appropriate installation method based on the actual installation environment, such as threaded connection, flange connection, etc.
Range and output signal: Select the appropriate range and output signal according to actual needs to meet the requirements of industrial automation systems.
Directional effect: Incorrect installation, vibration, or system maintenance may cause a change in the orientation of the sensor, known as directional effect. Choose sensors that can resist directional effects, or take measures to ensure that the installation direction of the sensor is consistent with its calibration to reduce the impact of directional effects.
Vibration impact: Low frequency vibrations from nearby motors or fans may affect the performance of the sensor. Choose a sensor with anti vibration capability or take measures to install the sensor in area 2 away from the vibration source.
Overvoltage protection: For applications such as leak detection systems, overvoltage protection is an important consideration factor. Choose sensors with overvoltage protection function, or ensure that the system design can provide appropriate overvoltage protection.
In summary, when selecting a differential pressure sensor, it is necessary to comprehensively consider basic parameters such as measurement range, accuracy, stability, installation method, range, and output signal, as well as special requirements such as directional effects, vibration effects, and overvoltage protection, to ensure that the sensor can accurately and reliably meet the specific application needs
