Fixed Nitric Oxide (NO) Gas Detector, 0 to 250/500/1000 ppm

The fixed nitric oxide gas leak detector is used to monitor NO concentration in different environments or pipelines. The measurement range is 0 to 250/500/1000 ppm. The gas monitor detects hydrogen sulfide online 24 hours a day and issues an audible and visual alarm. The infrared remote control is explosion-proof, the working voltage is 12-30V DC, and the output signal is three-wire 4-20mA standard signal output and RS485 signal output.

Features

• Adopting high precision sensor for accurate gas leak detection.
• Equipped with 3-wire system 4-20mA analog output, relay output, RS485 output (optional).
• Compatible with various controlled alarms, PLC, DCS and other control system, and can be remote monitored.
• Explosion-proof design, fast, relaible and stable.
• Infrared ray controller can remote control the alarm point settings, zero calibration, and address modification.
• Two-stage alarm with sound and light, and the alarm point is settable.
• With self-calibration function, and three standard keys will be used to realize on-site maintenance.
• Can output one or two on-off signals, can drive ventilator, solenoid valve or other external devices.

Tips: Installation of Fixed Hydrogen Sulfide (H2S) Detector

A fixed nitric oxide (NO) gas detector is a device specially designed to monitor the concentration of nitric oxide gas in the environment. The gas leak detectors are widely used in industrial, chemical, gas, environmental protection, and medical fields to ensure that the concentration of nitric oxide is within a safe range and to sound an alarm once the concentration rises.

Working Principle and Composition

1. Sensor: Fixed NO gas detectors are usually equipped with nitric oxide gas sensors. Common gas sensor types include electrochemical sensors, optical sensors, and chemical sensors. These gas sensors work on different principles, but all detect the presence of nitric oxide molecules.
2. Data Acquisition: The gas leak detector sensor generates an electrical signal or other sensing signal by detecting the concentration of nitric oxide gas in the surrounding environment.
3. Data Processing: The generated signals are fed into a built-in microprocessor or control unit for data processing and analysis.
4. Alarm Systems: Gas monitors are often equipped with gas alarm systems with sound, light, or digital interfaces, and often the ability to transmit information to a monitoring center. When the nitric oxide concentration exceeds the set safety threshold, the gas alarm system is triggered to notify the operator to take necessary measures.
