Principle
The hydrogen cyanide detector adopts the principle of catalytic combustion detection and detects the concentration of HCN gas through the diffusion Sampling method. The Sensor converts the gas concentration into an electrical signal, which is processed by the MCU chip and outputs 4-20mA, RS485, switching signal and other signals to realize the gas concentration monitoring and alarm function.
Applications
Workplace environment Gas detection, industrial process control, safety monitoring system

Notice
• Operating ambient temperature range -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• Sensor life 2~ 3 years, depending on Operating Environment
• The connection cable needs to choose a three-core Shielding cable (4~ 20mA) or a four-core cable (RS485), when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer is connected to the earth
• The explosion-proof form is explosion-proof, and the installation must meet the explosion-proof requirements
• Optional Accessories such as Power Adapter, Computer Monitoring Accessories, etc., at the user's own expense
• Alarm settings support conventional high and low alarms and interval control alarms
