Pressure range and accuracy requirements for pressure transmitters

Pressure transmitters are commonly used pressure measuring instruments in industrial sites, widely used in various industrial automatic control environments, involving fields such as water conservancy, hydropower, railway transportation, petrochemical, and pipelines. When selecting a pressure transmitter, consideration should be given to its pressure range and accuracy level. This article will provide a detailed introduction to the pressure range and accuracy level of pressure transmitters.

1、 Pressure range

Pressure category refers to the pressure category that can be detected by the pressure transmitter. Different types of pressure transmitters have different pressure categories, usually based on larger measurement pressures. For example, the pressure category of pressure transmitters is generally 0-1.6MPa, the pressure range of pressure transmitters is generally 0-10mpa, and the pressure range of differential pressure transmitters is generally 0-10kpa.

When selecting a pressure transmitter, the corresponding pressure category should be selected according to the needs of the specific application field. If the detection range of the pressure transmitter is too small, it cannot meet the needs of practical applications; If the detection range of the pressure transmitter is too large, it will affect the detection accuracy and stability. Therefore, when selecting a pressure transmitter, the appropriate pressure category should be selected based on the needs of the specific application field.

2、 Accuracy level

Accuracy refers to the deviation between the output signal of the pressure transmitter and the actual pressure value. Generally expressed as a percentage or square root, such as 0.5% FS, 1% FS, etc. FS refers to the large pressure value that can be detected by the pressure transmitter in the full range.

When selecting a pressure transmitter, the corresponding accuracy level should be selected according to the needs of the specific application field. If the accuracy level is high, a pressure transmitter with higher accuracy should be selected, but the price will also be higher. If the accuracy level is low, a pressure transmitter with lower accuracy can be selected, but it should be noted that the measurement error should not exceed the requirements of specific application fields.

It should be noted that the accuracy of pressure transmitters is not only related to their own performance, but also to their installation and usage methods. For example, during the installation process, it is necessary to prevent excessive vibration and impact of the pressure transmitter, in order to avoid affecting its detection accuracy and stability. It is necessary to prevent exceeding the rated pressure range to avoid affecting its detection accuracy and lifespan.

After reading the above content, you should be very clear about the pressure range and accuracy level of the pressure transmitter.
