Measurement has value when the response is defined.
Three conceptual arrangements for application discussions. These diagrams show functional relationships rather than approved safety designs.
Fixed-point monitoring
Local measurement at engineered monitoring points. Location and coverage depend on the release scenario, airflow, occupancy and objective.
- 01Gas-specific detector
- 02Controller / PLC interface
- 03Local alarm & defined response
- 04Event and service records
Conceptual only. Detector locations, gas ranges, setpoints, certifications and safety actions require qualified project review.
Remote sampling
Bring a compatible gas sample to an accessible instrument. Review tubing, conditioning, flow supervision, transport delay and gas losses before selecting this arrangement.
- 01Engineered sample point
- 02Compatible tubing & conditioning
- 03Instrument with flow supervision
- 04Alarm interface & records
Conceptual only. Detector locations, gas ranges, setpoints, certifications and safety actions require qualified project review.
Controller, alarm & network
Coordinate gas and fault indications with operator response and plant interfaces. Required safety functions need an independently reviewed architecture and cause-and-effect basis.
- 01Detector and fault signals
- 02Controller / engineered logic
- 03Alarm / ventilation interface
- 04PLC / BMS / SCADA record
Conceptual only. Detector locations, gas ranges, setpoints, certifications and safety actions require qualified project review.
