The Selection skills of pressure transmitters

- Sep 02, 2020-

1. Confirm the type of pressure

Pressure types of pressure transmitter UPB13 mainly include gauge pressure, absolute pressure, and differential pressure. Gauge pressure refers to the pressure based on the atmosphere, which is less than or greater than the atmospheric pressure; absolute pressure refers to the absolute pressure based on zero and higher than the absolute pressure; differential pressure refers to the difference between two pressures.

2. Confirm the pressure range

Under normal circumstances, the actual measured pressure is selected as 80% of the measurement range.

3. Confirm the measuring media

According to the different measuring medium, it can be divided into dry gas, gas liquid, strong corrosive liquid, viscous liquid, high temperature gas liquid, etc. The correct selection according to different media is beneficial to prolong the service life of the product.

4. Confirm the maximum overload of the system

The maximum overload of the system should be less than the overload protection limit of the transmitter, otherwise it will affect the service life of the product or even damage the product.

5. Confirm the accuracy level

The measurement error of the pressure transmitter UPB9 is divided according to the accuracy level. Different accuracy corresponds to different basic error limits (expressed as a percentage of the full scale output). In actual application, the selection is made according to the control requirements of measurement error and based on the principle of economy.
