What Factors Affect the Stability of Pressure Sensor?
Pressure sensors are one of the most commonly used sensors in industrial practice and are widely used in a variety of industrial automation environments and many other industries. When purchasing a pressure sensor, the stability of the product is a major consideration. What are the factors that affect the stability of pressure sensors? Next, we will detail the factors that affect the stability of pressure sensors.
The ability of a pressure sensor to remain unchanged after a certain period of use is called stability. In addition to the structure of the pressure sensor, the main factor affecting the long-term stability of the pressure sensor is the environment in which the sensor is used. Therefore, to make the pressure sensor has good stability, the sensor must have a strong environmental adaptability.
3 factors affecting the stability of pressure sensor
- Range: To choose the correct pressure range, the first step is to determine the maximum pressure measurement value of the system equipment, and generally should choose a pressure sensor 1.5 times larger than the maximum value of the medium. This is because of the need to consider the irregular fluctuations in the liquid medium above the peak when subjected to pressure shock, so as not to damage the instrument.
- Environmental conditions: The environmental adaptability of the pressure sensor can greatly affect its stability, so the appropriate sensor should be selected according to the environment. Appropriate measures should be taken to minimize the impact on the environment.
- Quantitative indicators: There is a quantitative indicator for the stability of the pressure sensor. At the end of its service life, it should be recalibrated to determine if the sensor's performance has changed.
In some cases where pressure sensors can be used for long periods of time and are not easily replaced or calibrated, the selected pressure sensor has more stringent requirements for stability and should be able to withstand long-term testing.
These are the factors that affect the stability of the pressure sensor. In addition to the stability of the pressure sensor, it is also useful to know the correct use of the pressure sensor to improve the efficiency in use. Regular maintenance of the instrument can improve the performance and extend the service life of the instrument to a certain extent.
