The SIS (Safety Instrument System) is a core system in the field of industrial safety, primarily used to monitor, assess, and control potential hazards in high-risk industrial processes. It ensures that safety measures are triggered in a timely manner when process abnormalities occur, preventing accidents or mitigating their consequences.
Application Area
Chemical / Petrochemical Industry: Emergency Shutdown (ESD)/Pipeline Shutdown (PSD) for Oil and Gas Pipeline Leakage
Nuclear Power: Reactor Emergency Shutdown (SCRAM)
Pharmaceutical / Chemical / Oil & Gas: Interlocking Isolation for Toxic Gas Release (such as Gas Detection System)
Environmental Protection, Exhaust Gas Treatment (such as the Burning Management System)
Chemical/Oil and Gas: Fire and Gas System (F&G)
Typical System Architecture
System Function Introduction:
Real time security monitoring and diagnosis
Safety interlock and emergency action
Independence and high reliability
Safety Integrity Level (SIL) certification
Fail Safe Design
Event recording and accident tracing
Interaction with external systems
Maintenance and Testing Management
Main Applications:
System Type: GDS
System Type: Burning Management System
Software: SIMATIC PCS7
Project Scope: EPC project
Delivered Function:
Combustible and toxic gas detectors are installed in the SPG workshop, TF workshop, and various Class A warehouses as flame detectors for gases that are prone to spontaneous combustion (AsH3, PH3, B2H6, SiH2Cl2, etc.)
The signal from the gas detector is transmitted to the Life Safety System (LSS) in the fire control room of the factory area, which displays the concentration of flammable and toxic gases in real time
Alarm for detector concentration exceeding limits and flame detection, and trigger safety interlock actions to prevent fires, explosions, or personal accidents
