In many industrial applications, the role of pressure sensors is crucial. They can accurately measure the pressure on the surface of objects, thus playing an important role in multiple industries such as machinery, electronics, and automobiles. However, in order to maintain this accuracy, the calibration and zeroing of pressure sensors cannot be ignored. This article will provide a detailed introduction to the zero adjustment principle, calibration principle, and operation method of pressure sensors, in order to improve the measurement accuracy and reliability of the sensors.

####Zero adjustment principle
Zero adjustment refers to setting the output value of the pressure sensor to zero before starting the measurement. This step is to eliminate zero drift caused by external factors such as temperature, pressure changes, or mechanical vibration, ensuring the accuracy and stability of the sensor output value.
####Calibration principle
The calibration criteria are the process of correcting errors between sensor output values and actual measured values. This operation is of great significance for eliminating sensor drift and improving measurement accuracy. During the calibration process, the output value of the sensor needs to be compared with the standard measurement value and the sensor parameters adjusted to eliminate errors.
####Zeroing and calibration methods
**Automatic zero calibration function: Modern pressure sensors are often equipped with automatic zero calibration function, which can automatically detect and eliminate zero drift during the initial operation of the equipment, ensuring stable output values.
**Manual zero adjustment * *: For sensors that do not have automatic zero calibration function, manual zero adjustment can be used. Firstly, place the sensor in a pressure free state and connect the measuring equipment. Then, adjust the zero point according to the sensor manual.
###Conclusion
Correct zeroing and calibration are crucial for the performance of pressure sensors. By regularly performing these maintenance operations, it can be ensured that the sensor provides accurate and reliable measurement results throughout its entire service life. With the continuous advancement of sensing technology, future sensors may integrate more intelligent calibration and zero adjustment functions, further simplifying operational processes and improving work efficiency.
