For more than 60 years, GfG has been committed to protecting people, industrial facilities and the environment by developing and manufacturing gas detection systems. With an extensive range of portable gas detectors and fixed gas detection systems, GfG can supply you with a selection of products for many applications and industries. Our scope also includes on-site service and advanced training courses.
We are specialists for gas detection solutions, not generalists in safety. No one can be the best at everything, but if you focus on one thing, you can achieve excellence. We work hard to provide you with the best gas detection equipment available, so you can focus on your task without having to worry about the risks that gases can pose. Because of that we invest more heavily in research and development than any other company. Approximately 13% of our annual turnover is reinvested in basic research and the development of new sensors and devices.
This includes finding solutions for customers whose requirements are not met by “off the shelf” products. We take pride in our longstanding cooperation with the Singapore Civil Defence Force (SCDF), for example. For many years now, they have put their trust in GfG’s portable devices, which we optimized to adapt to the Singaporean climate and fulfill the special requirements for integration into the SCDF communication network.
The IR22 uses an infrared sensor (IR) to detect carbon dioxide and the combustible gases methane and propane. The long-life sensors make the IR22 an economical solution for detecting gases in measuring ranges such as 0 to 10,000 ppm, 0 to 100 LEL or 0 to 50 % by volume. Automatic temperature compensation and linearisation of the measuring signals ensure high measuring accuracy.
Functional safety and device protection
The hardware of the IR22 complies with the European Standard for Functional Safety DIN EN 61508-2: 2011 (SIL). The housing is protected against the ingress of dust and water (protection class: IP54). An optional weatherproof housing provides additional protection.
Communication and service
Signals are transmitted according to the analogue industrial standard (optionally 0.2-1 mA or 4-20 mA) or via the digital RS-485 interface (Modbus protocol). The transmitter indicates operating states via two status LEDs. Service and adjustments are carried out on site using the optional RC22 remote control (one-man adjustment). Test gases can be applied for function control with a calibration adapter.
