In the chemical industry, reaction vessels are usually used as core equipment when it comes to synthesis, polymerization, catalysis and other reaction processes. The reaction kettle can meet strict process conditions such as high temperature, high pressure, and high vacuum, and the pressure measurement system is the core guarantee of process safety. However, these harsh environments also pose serious challenges to pressure detection in production processes, such as the long-term stability, corrosion resistance, and detection accuracy of pressure transmitters. We will analyze the measurement difficulties on the customer's site and provide reasonable solutions to meet these needs, helping the customer achieve a safer, more efficient, and economical pressure level measurement solution.

The customer's carbonization reaction kettle process section has harsh working conditions:Pressure -97kPa, temperature up to 280 ℃, corrosive acidic mediumLong term use of pressure transmitters is required to monitor process parameters and ensure stable operation of the production line. In recent years, the customer has introduced multiple domestic brand pressure transmitters that they cannot tolerateharshDue to conditions such as inaccurate output and membrane bulging, the instrument product needs to be replaced within 1-2 months. This not only increases maintenance costs, but also affects overall efficiency due to production downtime, and may even pose safety hazards due to inaccurate monitoring. The customer urgently needs a pressure monitoring solution that is resistant to high temperatures, high vacuum, and long-term stability to enhance production safety and economic benefits.
