Overview
The BOSEAN K-G60 (SO2) is a stationary gas detector designed for sulfur dioxide (SO2) Gas detection with a range of 0 to 20 ppm and options of 0 to 50/1000 ppm. The instrument is Wall-Mounted, Piped, Flow-Through or Pump-Suction mounted and supports a variety of Sensor and Transfer modes for gas monitoring in industrial environments.
Features
1. Multi-range optional: 0~ 20ppm, 0~ 50ppm or 0~ 1000ppm, resolution 0.1/1 ppm.
2. Sensor support: electrochemistry, catalytic combustion, semiconductor, PID light ion, infrared gas Sensor.
3. Installation method: Wall-Mounted, pipe type (thread size M35X1.5mm), flow type, pump type optional.
4. Multiple transmission methods: standard 4-20mA and RS485 (MODBUS RTU protocol), optional 433MHz wireless transmission.
5. High Accuracy Detection: detection accuracy ≤ +/- 3% F.S, Linearity ≤ +/- 1% F.S.
6. Quick Response: Response Time ≤ 20s, Recovery Time ≤ 20s.
7. Explosion-proof protection design: Explosion-proof mark Exd II T6 GB and CNEx16.0449, Protection Rating IP65.
8. Relay output: two sets of relays, contact point capacity 30VDC 2A/220VAC 0.3A.
Principle
Gas detector detects sulfur dioxide gas concentration in the environment with built-in Sensors such as electrochemistry, catalytic combustion, semiconductor, PID photoion or infrared Sensor. Sensor converts gas concentration into electrical signal, after processing by internal circuit, output standard signal (such as 4-20mA or RS485), and can trigger alarm through relay. The instrument uses MODBUS RTU protocol for data transmission, ensuring real-time monitoring and remote control.
Applications
Industrial gas monitoring, environment safety testing, chemical production, Petrochemicals, sewage treatment, warehousing and logistics, laboratory research
Standards
Exd II T6 GB、CNEx16.0449
Steps
1. Select the Installation method: Wall-Mounted, Pipeline, Flow or Pump Suction, and ensure that the thread size is M35X1.5mm.
2. Connect power supply: Use DC24V +/- 15% power supply, connect 3X1.5mm2 Shielding cable through M20x1.5 or G1/2 interface.
3. Configure the transmission method: connect 4-20mA output or RS485 interface, optional 433MHz wireless transmission.
4. Set the alarm point: low alarm point 5PPM, high alarm point 10PPM.
5. Start detection: After power on, the instrument automatically detects the gas concentration, and the Response Time is ≤ 20s.
6. Monitoring output: real-time monitoring of data through relay output or transmission of signals.
Notice
• Ambient Temperature should be kept in the range of -20~ 50 ℃ to avoid extreme temperature affecting performance.
• Environmental humidity should not exceed 95% RH to prevent condensation and condensation from damaging the instrument.
• Ensure that the Operating Pressure is between 86 and 106Kpa during installation to avoid errors caused by abnormal pressure.
• Connect with designated 3X1.5mm2 Shielding cables to ensure signal stability and anti-interference.
• Regularly check Sensor zero drift, no more than +/- 1% F. S per year, calibrated if necessary.
• For use in explosion-proof environments, it must comply with Exd II T6 GB and CNEx16.0449 standards to avoid potential safety hazards.
• Relay output load does not exceed 30VDC 2A or 220VAC 0.3A to prevent overload damage.
