Principle
The detector adopts the principle of catalytic combustion detection, and detects the concentration of phosphorus trifluoride gas through the diffusion Sampling method. Sensor converts the gas concentration into an electrical signal, which is processed by MCU chip and converted into a standard Output signal.
Applications
Industrial environment Gas detection, toxic gas monitoring, safety production monitoring

Notice
• Operating voltage range DC12V~ 30V
• Ambient Temperature -20~ 50 ℃
• Environmental humidity 10-95% RH (non-condensing)
Sensor life 2-3 years, depending on Operating Environment
• Cable selection: 4~ 20mA choose three-core Shielding cable, RS485 choose four-core, when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm.
• Shielding needs to be connected to the earth
• The explosion-proof form is flameproof
• Optional Measurement Certificate, user pays
