Product Description
GAC-M20 Continuous-Sampling Gas Detection Cabinet
Dedicated sensor per monitoring point with self-protecting sampling design for high-consequence gas detection applications.
Technical Overview
In critical monitoring scenarios where missed readings carry severe consequences, the GAC-M20 ensures reliability by providing each monitoring point with its own dedicated sensor. Continuous pump-suction sampling eliminates polling delays, delivering real-time gas detection.
Operating Principle
- Sample Transport: Centralized pump actively draws gas from monitored spaces through dedicated sampling lines
- Dedicated Sensing: Each of 8 channels operates with its own sensor, eliminating cross-contamination and measurement sharing
- Self-Protection: Built-in detector monitors cabinet interior; triggers alarm, cuts pump power, and initiates purge via external gas source upon leakage detection
- Data Path: 9 channels of 3-wire 4-20 mA output deliver results directly to central gas alarm control cabinet
Sampling Line Design
- Eight independent sampling channels, each with dedicated line and sensor
- Maximum sampling run of 100 meters to maintain transport delay and response time within design limits
- Supplied filters installed at sampling points to prevent condensate and particulate from reaching sensors
- Front-end shut-off ball valves enable single-line isolation for maintenance without cabinet shutdown
- Purge function requires oil-free, dry instrument gas at 0.3 - 0.6 MPa
Performance Features
- Independent sensor per monitoring point - eliminates cross-talk, increases reliability
- Pump-suction sampling - actively draws gas from monitored space
- Multi-channel continuous active sampling - 8 independent sampling channels
- Front-end filters and shut-off ball valves - maintenance-friendly, safe isolation
- Flame arrestors at inlet and outlet - intrinsic safety design
- Built-in leakage gas detection alarm - internal pipeline self-protection
- External gas-source replacement - automatic purge after leak event
- Direct data feed to central control cabinet - seamless system integration
Interfaces & System Integration
Outputs 9 channels of 3-wire 4-20 mA directly to central gas alarm control cabinet. Compatible with GT-C100, GQ-C100G and GQ-C100B detectors for oxygen, methane, hydrogen and additional gases on request.
Typical Applications
LNG cargo tanks, LNG fuel tanks, and other high-risk confined spaces onboard vessels requiring continuous gas monitoring.
