Principle
The benzene detector adopts the principle of catalytic combustion detection and detects gas concentration by diffusion Sampling method. Sensor converts the detected gas concentration signal into an electrical signal, and outputs 4-20mA analog signal, RS485 digital signal or switching signal after processing by MCU chip to realize accurate measurement and remote transmission of gas concentration.
Applications
Industrial Gas detection, environment monitoring, safety protection, chemical production, Petrochemicals, metallurgy, electric power, sewage treatment, Food processing, pharmaceutical manufacturing
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 to ensure that the electrical interface is connected correctly
2. Connect DC24V Power Supply
3. Set the alarm value, zero adjustment, calibrate and other parameters through the remote control or display screen
4. Start the detector for gas concentration monitoring
5. Connect PLC, DCS, DDC and other Control systems or wireless transmission modules as needed
6. Regularly maintain and calibrate Sensors
Notice
• Operating voltage range is DC12V~ 30V to ensure stable power supply
• Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• Sensor life 2~ 3 years, need to be replaced regularly according to the Operating Environment
• When connecting the cable, choose three-core Shielding cable for 4~ 20mA, and four-core for RS485. When the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer needs to be grounded.
• The explosion-proof form is explosion-proof, and the installation and maintenance must comply with the explosion-proof requirements
• Alarm settings support conventional high and low alarms and interval control alarms, which can be configured as needed
• Optional Accessories such as Power Adapters, Converters, etc. need to be installed and used correctly
