Factors Affecting the Stability of Pressure Sensor

Pressure sensor is one of the most commonly used sensors in industrial practice, which is widely used in various industrial automation environment and many other industries. In the purchase of pressure sensors, the stability of the product is a major consideration. What factors affect the stability of pressure sensors? Next, we will introduce in detail what factors affect the stability of pressure sensor.

The ability of a pressure sensor to remain unchanged after using a certain time is called stability. In addition to the structure of pressure sensor, the main factors that affect the long-term stability of pressure sensor are the use environment of sensor. Therefore, to make the pressure sensor have good stability, the sensor must have strong adaptability to the environment.

  1. Range: To select the correct pressure range, first 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 it is necessary to consider the irregular fluctuation above the peak of the liquid medium when it is hit by pressure, so as not to damage the instrument.
  2. Environmental Conditions: The environment adaptability of the pressure sensor will greatly affect its stability, so choose the appropriate sensor according to the environment. Appropriate measures should be taken to minimize the impact of the environment.
  3. Quantitative Index: The stability of the pressure sensor has a quantitative index. After the service life, it should be re-calibrated to determine whether the performance of the sensor has changed.

In some situations where pressure sensors can be used for a long time and cannot be easily replaced or calibrated, the selected pressure sensor requires more stringent stability and should be able to stand the test for a long time.

These are the factors that affect the stability of pressure sensor. In addition to the stability of the pressure sensor, the correct use of the pressure sensor can be understood, which is conducive to improving work efficiency in use. Regular maintenance and maintenance of the instrument can improve the performance of the instrument and extend the service life of the instrument to a certain extent.
