Before selecting sensors, rapheries should perperm a faciliy- wide study identifying thee specific gases, pressure profiles, and temperatur ranges at each unit. Process hazard analyses (PHA) are a good starting point, supplemented by quantitativa risk assessments (QRA) that model emission equios.

Choose Sensors with contribute Range and Certification

Sensor ranges mutt match expected concentrations. For example, a PID used for benzene detaction should have a range of 0- 50 ppm, while a pastistitible gas detactor for metane should cover 0- 100% LEL. All sensors should carry certifications from agencies like e.1; for use in classified hazardoes (Class I, Division 1 2).

Sensors from multiple vendors should d feed into a compatin data platform that handles time- stamped logging, trend analyses, and reporting. Open standards like OPC UA facilitate equivability. The platform must support automated alerting to dispatch teams for equivate response and maintain a searchable ef for root- cause analysis post- incident.
