Principle

The detector adopts the principle of catalytic combustion detection and detects nitric oxide gas by diffusion Sampling method. Sensor converts the detected gas concentration signal into an electrical signal, and outputs a standard signal after processing by MCU chip.

Applications

Chemical, petroleum, metallurgy, electric power, environmental protection, municipal, fire protection, mining, warehousing, laboratories and other industrial sites where nitric oxide gas exists

Standards

GB/T3836.1-2021、GB/T3836.31-2021、GB3836.15-2000、GB12476.1-2013、GB12358-2006、GBZ2.1-2007、GB4208-2008

Steps

1. Determine the installation location and fix the detector 2. Connect power cord (DC24V) and signal output line 3. Set the alarm value, zero adjustment, calibrating and other parameters through the remote control 4. Start the detector to work normally 5. Monitor detection data through LCD display or remote equipment

Notice

• Ensure that the electrical interface is well sealed during installation • Ambient Temperature should be kept in the range of -20~ 50 ℃ • Environmental humidity should be maintained at 10-95% RH (no condensation) • When the transmission distance exceeds 1000 meters, a single cable with a wire diameter ≥ 1.5mm needs to be used • Shielding must be grounded Sensors have a lifespan of 2 to 3 years and need to be replaced regularly • Strict compliance with explosion protection requirements when used in explosive environments • calibrating and repairs should be carried out by professionals
