Product Overview

The KD-5 Combustible Gas/Hydrogen Sulfide Transmitter is a high-performance gas detection device designed for real-time monitoring of combustible gases and hydrogen sulfide in industrial environments. With a compact structure, it facilitates easy installation and integration, suitable for industries such as petrochemicals, metallurgy, and power plants. Its core function is to detect gas concentrations via high-sensitivity sensors and output a standard 4-20mA signal, compatible with DCS or PLC systems for automated control. The device operates on DC24V power and features a three-wire connection for simplified operation and enhanced stability.2 7 12

Technical Features

The KD-5 utilizes a catalytic combustion principle for combustible gas detection and a semiconductor-based thermal conductivity method for hydrogen sulfide, ensuring accurate response to different gases. Its detection range covers 0～100%LEL for combustible gases (or 0～1000/2000ppm) and 0～30/50ppm for hydrogen sulfide, meeting diverse monitoring needs. The built-in setting tool allows on-site zero adjustment, span calibration, and concentration reading, simplifying maintenance. Designed with pressure-resistant explosion-proof housing (d2G4 or d3acG4 for KD-5A), it operates reliably in harsh environments within a temperature range of -10℃～60℃.5 10 19

Applications

The KD-5 is widely used in locations with potential leaks of combustible gases or hydrogen sulfide, including chemical plants, natural gas pipelines, and wastewater treatment facilities. Its diffusion-based detection method ensures rapid response to gas concentration changes, while real-time data transmission supports timely safety interventions. The compact design allows seamless integration into existing systems, making it ideal for both fixed and mobile monitoring applications to enhance industrial safety.3 11 15
