3051 High-Precision Stainless Steel Industrial Pressure Transmitter 0.3 - 10000 PSIA 4 - 20mA IP67

Industrial pressure transmitters are core measuring instruments in industrial automation used to measure the pressure of liquids, gases or steam and convert it into standard electrical signals (such as 4-20mA DC). They are widely applied in industries such as petroleum, chemical engineering, power, metallurgy, and water treatment.

Their key parameters include measurement type (gauge pressure/absolute pressure/differential pressure), range, accuracy (such as 0.1%FS), output signal (4-20mA is the main type), as well as material and explosion-proof grade.

 When selecting a model, it is first necessary to clarify the pressure type: gauge pressure (relative to atmospheric pressure), absolute pressure (relative to vacuum), or differential pressure (the pressure difference between two points).

 Secondly, the working conditions need to be calculated: the range should be about 1.5 times the maximum working pressure, the material in contact with the medium must be resistant to corrosion by the medium, and the temperature range and explosion-proof requirements also need to be considered.
