At present, when the safety of production is concerned in the petrochemical industry, single flange capillary pressure transmitter plays a key role in the pressure monitoring of propylene ball tank, bringing a new solution for the storage safety of inflammable and explosive chemical raw materials.
As an important chemical raw material, propylene should be stored in a sphere tank at room temperature in liquid state. Its pressure monitoring faces three major challenges: Propylene has strong volatility and inflammable and explosive characteristics, traditional pressure measurement methods have leakage risks, and it is easy to cause measurement distortion due to temperature changes, which poses a serious threat to the safe operation of the sphere tank.
The single flange capillary pressure transmitter solves these problems perfectly with its unique design: Absolute sealing ensures safety: This device uses a fully welded sealing structure, where the propylene medium only contacts the isolation diaphragm at the flange end, and the pressure is transmitted to the remote transmitter body through the silicone oil in the capillary, completely eliminating the potential leakage points in traditional measurement methods.
Key techniques for precision measurement:
High temperature stable silicone oil is selected as the conduction medium to ensure the accuracy and stability of pressure measurement when the surface temperature of the sphere tank changes violently.
Intelligent monitoring improvement:
The new generation of products is equipped with HART communication protocol, which can transmit pressure data to the central control room in real time, and achieve intelligent functions such as pressure trend warning and limit alarm, so as to provide digital support for the safety management of the sphere tank.
Industry experts said that the application scope of single flange capillary pressure transmitter will gradually expand from propylene ball tank to other storage equipment of flammable and explosive media, providing more complete technical support for the safety production of chemical industry.
