People usually convert the measured physical or chemical quantity into a device or element called a sensor (also known as a converter). Among them, temperature, humidity, mass, weight, force, pressure, speed, acceleration, length, angle, liquid level, flow rate, density, etc. are usually contacted with more physical quantities. Correspondingly, temperature sensors are needed in production and life. , humidity sensor, weighing tension sensor, pressure sensor and so on.
Before selecting a sensor, investigate its use environment, and select a suitable sensor according to the detailed use environment, or take appropriate measures to reduce the impact of the environment. Therefore, in order to make the sensor have good stability, the sensor must have a strong ability to adapt to the environment.
The ability of a tension sensor to remain unchanged after a period of use is called stability. There are quantitative indicators for the stability of the sensor. After the usage period is exceeded, it should be re-calibrated before use to determine whether the function of the sensor has changed. In addition to the structure of the sensor itself, the factors affecting the long-term stability of the sensor are mainly the environment in which the sensor is used. In some occasions where the sensor is required to be used for a long time but cannot be easily replaced or calibrated, the selected sensor has stricter stability requirements and must be able to withstand the test for a long time.
