Riken Keiki SD-3 represents a new level of functionality, reliability, and durability. The SD-3 can monitor a very wide range of Combustible (including Hydrogen) and Toxic Gases, Oxygen in ATEX Zones and harsh environments.
SD-3 is a step up from existing gas detectors having stainless steel construction, multiple communication protocols that include 4-20mA, Modbus and HART. There are 2 alarm relay contacts and a fault alarm. This is double that of the predecessor model.

3 x year sensor warranty.
Explosion-proof certifications in different countries (ATEX/IECEx, Japan Ex (Japan), FM/cFM), CE marking, SIL 2 (IEC 61508) EN performance approval.
Supports Modbus (RS-485) communication in addition to 4 - 20 mA output + HART communication.
Flexibility for any application.
Stainless steel SCS14 (SUS316 equivalent), protection rating equivalent to IP66/67, compatible with wide temperature range (-40 - +70 °C).
Allows monitoring of sensor life for optimal & cost effective replacement strategy.
Diffusion, aspirator, remote sensor & duct insertion versions.
The SD-3 Series are fixed explosion-proof gas detectors that continuously monitor for combustible gases, toxic gases, and oxygen in the surrounding atmosphere. These gas detectors detect gas leaks and activate an alarm when pre-set concentrations are exceeded.
Detected gas concentrations are converted and output as 4-20 mA analog and digital HART signals. Output options include Modbus (RS-485) communication and the use of three relays. The rugged housing construction (material: stainless steel, protection rating equivalent to IP66/67) allows use in a wide temperature range (-40 - +70 °C).
A range of different mounting types (e.g., wall, pole, and duct mounted) support a variety of uses and installation environments.
These global products are certified explosion-proof in various countries, and meet the requirements of various international standards, including IEC/EN performance and SIL 2 certification.
