Principle
The detector adopts the principle of catalytic combustion detection and detects combustible gas by diffusion Sampling method. When the gas diffuses to the Sensor, the Sensor generates an electrical signal proportional to the gas concentration, and outputs the corresponding analog or digital signal after processing by the MCU chip.
Applications
Combustible Gas detection, Explosive environment monitoring, Hazardous place safety monitoring, Industrial process control, Environment Gas detection alarm
Standards
GB/T3836.1-2021、GB/T3836.31-2021、GB3836.15-2000、GB12476.1-2013、GB12358-2006、GBZ2.1-2007、GB4208-2008
Steps
1. Install the detector in the right location
2. Operating voltage DC24V
3. Connect the signal output cable (three-core Shielding cable or four-core cable)
4. Set the alarm value, zero adjustment, calibrating and other parameters through the remote control
5. Start the detector for gas concentration monitoring
6. Connect external alarm device or Control system as needed
Notice
• Ensure that the electrical interface is well sealed during installation
• When the transmission distance exceeds 1000 meters, a single cable with a wire diameter ≥ 1.5mm needs to be used
• Shielding must be grounded
• Working ambient temperature range -20~ 50 ℃
• Environmental humidity range of 10-95% RH (non-condensing)
Sensor life is 2-3 years depending on Operating Environment
• Explosion-proof form is Probe Transmitter and Sensor are flameproof
• Optional Accessories need to be configured according to actual needs
