Principle
The detector adopts the principle of infrared NDIR detection, and detects R22 Freon-22 and other gases through the diffusion Sampling method. The detected gas concentration signal is processed by the MCU chip and converted into 4-20mA, RS485, switching quantity and other standard signal output.
Applications
Industrial Gas detection, environment monitoring, safety protection, refrigeration system monitoring, chemical production, dangerous place monitoring
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, calibrating and other parameters through the remote control or Operating interface
4. The detector starts to work and displays the gas concentration in real time
5. Connect PLC, DCS, DDC and other Control systems or remote monitoring platforms as needed
6. Receive alarm information through sound and light alarm or remote notification
7. The alarm can be processed by infrared remote control with one-button silencing
Notice
• Operating voltage range is DC12V~ 30V, DC24V is recommended
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• When the transmission distance exceeds 1000 meters, a single cable with a wire diameter ≥ 1.5mm needs to be used
• Shielding must be connected to earth to ensure signal stability
• Sensor Life Approximately 10 Years, Depending on Operating Environment
• Pay attention to explosion-proof requirements during installation to ensure that the explosion-proof structure is intact
• Regular calibrating and maintenance to ensure detection accuracy
• Optional 220V to 24V Power Adapter and Computer Monitoring Accessories
