Principle
The ethylene detector adopts infrared NDIR detection principle, and detects C2H4 gas by diffusion Sampling method. The detected gas concentration signal is processed by MCU chip and converted into standard signal output.
Applications
Chemical industry, petroleum, gas, metallurgy, electric power, environmental protection, fire protection, medicine, Food processing, warehousing and logistics, sewage treatment, mining
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. When the concentration exceeds the set value, the sound and light alarm is triggered
6. It can be connected to the monitoring system through the switching control device or through the signal output
Notice
• Operating voltage range is DC12V~ 30V, please ensure that the supply voltage is within the range
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
• Connecting 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 must be connected to the earth
Explosion-proof level is Ex db IIC T6 Gb, please install and use as required in dangerous places
• Sensor Life Approximately 10 Years, Depending on Operating Environment
Regular calibrating and maintenance to ensure detection accuracy
