What is the OC-F08 Series Fixed Gas Detector and where is it used?
OC-F08 Series Fixed Gas Detector is a continuous gas monitoring system designed for permanent installation in industrial environments. It detects hazardous gases in real time and is widely used in oil & gas plants, chemical industries, manufacturing units, and utilities.
What does “4–20 mA output” mean and why is it important?
The 4–20 mA analog output is an industry-standard signal used to transmit gas concentration data to PLCs, SCADA systems, and control panels.
- 4 mA → Zero gas concentration
- 20 mA → Maximum calibrated range
This ensures reliable, noise-resistant communication over long distances, making it ideal for industrial automation.
What types of gases can the OC-F08 detect?
The detector can be configured to measure a wide range of gases, including:
- Combustible gases (LPG, methane, hydrogen)
- Toxic gases (CO, H₂S, NH₃, SO₂)
- Oxygen (O₂) monitoring
Different sensor types (electrochemical, catalytic, or infrared) are used depending on the gas.
What are the key features of the OC-F08 Series?
Key features include:
- Continuous real-time monitoring
- 4–20 mA + optional RS485 (Modbus) communication
- Explosion-proof and rugged housing for hazardous areas
- High-accuracy sensors with fast response time
- Local display and alarm outputs (audible/visual)
Where is the OC-F08 Series typically installed?
Typical installation areas include:
- Gas pipelines and storage areas
- Chemical processing zones
- Boiler rooms and confined spaces
- Manufacturing and industrial plants
It is critical for early leak detection, process safety, and regulatory compliance.
