Principle
The detector adopts the principle of infrared NDIR detection and detects gas by diffusion Sampling method. The detector converts the gas concentration signal into an electrical signal through intelligent Sensor technology, and then performs data processing and conversion through MCU chip, and finally outputs a standard signal.
Applications
Chemical industry, petroleum, gas, metallurgy, electric power, environmental protection, fire protection, mining, municipal administration, warehousing, laboratory
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. Regular maintenance and calibrating
Notice
• Operating voltage range is DC12V~ 30V, please ensure stable power supply
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• Pay attention to explosion-proof requirements during installation to ensure that the explosion-proof structure is intact
• Cable connection: 4~ 20mA choose three-core Shielding cable, RS485 choose four-core, when the distance exceeds 1000 meters, the single wire diameter is ≥ 1.5mm, and the Shielding layer is connected to the earth
• Wireless transmission module needs to be selected according to actual needs
• Sensor Life Approximately 10 Years, Depending on Operating Environment
• Alarm settings support conventional high and low alarms and interval control alarms
• Optional Accessories need to be purchased separately, Measurement certificate fee is paid by the user
