The accuracy level of the pressure transmitter refers to the maximum allowable error range of the difference between the pressure value and the reference value output by the pressure transmitter under certain conditions. According to international standards, the accuracy of pressure transmitters is generally divided into 0.1 class, 0.2 class, 0.5 class, 1.0 class, 1.5 class, 2.5 class, 4 class, etc. The corresponding measurement error ranges for each level are as follows:

Class 0.1 accuracy class: The permissible error range is ±0.05%. It is suitable for high-precision pressure measurement, such as chemical industry, laboratory, precision instruments and high-precision control systems and other important occasions.

Class 0.2 accuracy class: The permissible error range is ±0.1%. It is suitable for industrial occasions with high general requirements, such as compressors, pumps and some mechanical equipment.

Class 0.5 accuracy: The allowable error range is ±0.25%. It is suitable for general industrial pressure measurement and flow, liquid level and other parameter measurements.

Class 1.0 accuracy class: The allowable error range is ±0.5%. It is suitable for general industrial control and measurement of pressure, liquid level, flow rate and some measurement parameters.

Class 1.5 accuracy: The allowable error range is ±0.75%. It is suitable for general atmospheric pressure, air flow, heating furnace, fan and other industrial occasions.

Class 2.5 accuracy: The permissible error range is ±1.25%. It is suitable for rough industrial control and measurement of atmospheric pressure, liquid level and flow rate.

Class 4 accuracy class: The allowable error range is ±2%. It is suitable for large-scale equipment, pipelines and low-level instruments with low requirements.

When selecting a pressure transmitter, the pressure transmitter with the appropriate accuracy level should be selected according to the requirements of the actual application, weighing the accuracy level and cost.
