The Xi'an Gaoling waste incineration plant operates three large-scale incinerators. Flue gas pressure is directly linked to explosion risks and falls under a SIL3 safety loop, requiring regular calibration and documentation.

• Flue gas contains dust and sulfur, making it highly corrosive;
• Manual calibration of safety instruments (SIL) is labor-intensive and prone to errors;
• Clogged impulse lines lead to false alarms and unplanned shutdowns.

Cerabar PMC71B / PMP55 pressure transmitters featuring ceramic diaphragms, SIL Guide, CRC checksum, and HART communication.

• Ceramic diaphragm offers excellent wear and corrosion resistance, achieving 99.98% availability;
• SIL Guide enables one-click safe parameter verification, reducing calibration time by 80%;
• CRC checksum prevents accidental parameter changes, enabling traceable safety audits;
• Built-in clogging warning function reduces unplanned shutdowns by 70%.
