Overview
The BOSEAN K-G60 (NO) Stationary Gas Detector is a dedicated device for the detection of nitric oxide (NO) gas, with a range of 0 to 250 ppm and options of 0 to 500/1000 ppm. The instrument is Wall-Mounted, Piped, Flow-Through or Pump-Suction mounted, supports a variety of Sensor and Transmission modes, and is suitable for gas monitoring in industrial environments.
Features
1. Support electrochemistry, catalytic combustion, semiconductor, PID light ion, infrared gas Sensor, adapt to different detection needs.
2. Installation methods are diverse, including Wall-Mounted, pipeline type (thread size M35X1.5mm), flow type, pump type optional.
3. Flexible transmission mode, standard 4-20mA and RS485 (MODBUS RTU protocol), optional 433MHz wireless transmission.
4. High Accuracy Detection, detection accuracy ≤ +/- 3% F.S, Linearity ≤ +/- 1% F.S.
5. Fast Response and Recovery, Response Time ≤ 20s, Recovery Time ≤ 20s.
6. Explosion-proof design, explosion-proof mark Exd II T6 GB and CNEx16.0449, Protection Rating IP65.
7. Relay output, two sets of relay contact point capacity 30VDC 2A/220VAC 0.3A.
Principle
Gas detector detects nitric oxide gas concentration in the environment with built-in Sensors such as electrochemistry, catalytic combustion, semiconductor, PID photoion or infrared Sensors. Sensors convert gas concentration into electrical signals, which are processed and displayed over range and transmitted via 4-20mA, RS485 or wirelessly, while relay outputs are used for alarm control.
Applications
Industrial gas monitoring, environment safety testing, chemical production, Petrochemicals, metallurgical industry, warehousing and logistics, fire security
Standards
Exd II T6 GB、CNEx16.0449
Steps
1. Select the Installation method (Wall-Mounted, Pipeline, Flow or Pump Suction) and fix the equipment.
2. Connect the power supply (DC24V +/- 15%) and cable (3X1.5mm2 Shielding cable, connection method M20x1.5 or G1/2).
3. Configure the transmission method (e.g. 4-20mA, RS485 or wireless transmission).
4. Set the alarm point (low alarm 50PPM, high alarm 150PPM).
5. Start the equipment, monitor the gas concentration, and adjust the parameters as needed.
Notice
• Ambient Temperature should be kept in the range of -20~ 50 ℃.
• Environmental humidity should not exceed 95% RH to avoid condensation.
• Operating Pressure should be between 86~ 106Kpa.
• Connect using the designated cable (3X1.5mm2 Shielding cable).
• Regularly check Sensor zero drift to ensure accuracy （≤ +/- 1% F. S/year).
• Use in an explosion-proof environment, subject to relevant explosion-proof standards.
