Gas warning and measuring devices for almost all gases.

The new generation of gas detectors: SD-3 series

SD-3GH | Semiconductor sensor

Functions

• The new "F Sensor Series" sensor significantly improves both functions and
  performance
• New semiconductor sensor
• Complies with various global standards
• Wide range of output options
• Robust housing construction allows use even in harsh environments
• Wide range of types for a variety of applications and installation environments

The Riken Keiki SD-3GH series are permanently installed explosion-proof gas detectors that continuously monitor the surrounding atmosphere for COS, CS2, EO or H2S. These gas detectors detect gas leaks and trigger an alarm if preset concentrations are exceeded. Detected gas concentrations are converted and output as 4 – 20 mA analog and digital HART signals. Output options include Modbus communication (RS-485) and the use of three relays.

The robust housing construction (material: stainless steel, protection class corresponds to IP66/67) allows use in a wide temperature range (-40 – + 70 °C). A number of different mounting types (e.g. wall, pole and duct mounting) support a wide range of applications and installation environments. These SD-3 series detectors are certified as explosion-proof in various countries and meet the requirements of various international standards, including IEC/EN performance and SIL 2 certification.

Target gas: COS, CS2, EO, H2S
