Frequently Asked Questions
Which target gases can this detector measure?
The detector is designed for detecting combustible gases, specifically Methane and Propane, utilizing a catalytic combustion detection principle.
Does the device require an external controller to operate?
No, this is a stand-alone detector with power-up availability (AC220V) that operates independently without needing an external controller.
Can it trigger external ventilation fans or emergency shut-off valves?
Yes, the unit provides two linkage outputs (passive point + passive switch) capable of driving external devices such as exhaust fans and shut-off valves.
How is maintenance and parameter calibration conducted on-site?
On-site configuration and operation can be performed via infrared remote control without opening the explosion-proof enclosure lid.
What are the supported installation options?
The detector supports multiple flexible mounting options including Ceiling Installation, Wall Mount, Cross-pipe Installation, and Vertical Pipe Installation.
What are the explosion-proof and ingress protection ratings?
The detector is certified with an ExdⅡCT6Gb explosion-proof grade and provides an IP66 ingress protection rating, making it suitable for harsh industrial conditions.
