Principle
The detector adopts the principle of catalytic combustion detection, and detects Isopropanol gas by diffusion Sampling method. The detected gas concentration signal is processed by MCU chip and output standard signal.
Applications
Workplace environment Gas detection, industrial process control, safety monitoring, electrical installation in dangerous places
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 and connect the cable
2. Power Supply DC24V
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 standard, the detector issues a sound and light alarm
6. Data and control equipment can be monitored through remote systems
Notice
• Operating voltage range is DC12V~ 30V, please ensure stable power supply
• Working Ambient Temperature -20~ 50 ℃, Humidity 10-95% RH (non-condensing)
Sensor life is 2-3 years depending on Operating Environment
• 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
