Transmitter IR22

Product catalog summary

Overview: The IR22 Transmitter is designed for monitoring combustible gases and CO₂ using infrared technology. It is manufactured by GfG Gesellschaft für Gerätebau mbH in Germany and is part of their fixed gas detection systems.

Specifications: The IR22 uses adsorption spectra for selective monitoring, making it insensitive to sensor toxins and effective even in low oxygen environments. It supports both analog (4-20 mA or 0.2-1 mA) and digital (RS-485) communication, allowing integration with GfG controllers and PLCs.

Features: The transmitter processes data at the measuring point, offering linearization of signals, temperature compensation, malfunction detection, and maintenance alerts. It supports one-man calibration and adjustment, with a calibration adapter for regular checks.

Variants: The IR22 is available in a basic version and a variant with a display and acoustic alarm for on-site measured value display.

Technical Data: The IR22 measures gases like CO₂, Methane, Difluormethane, and Propane with various ranges. It operates within -25 to +50 °C, 0 to 95% humidity, and 80 to 130 kPa air pressure. The sensor has a lifetime of over 5 years with a response time of t90 < 50 seconds. It requires a power supply of 12 to 30 V DC and is housed in a plastic casing with IP54 protection.

Certifications: The IR22 complies with DIN EN 61508-2: 2011 for functional safety (SIL).

For monitoring combustible gases (HC) and CO₂ The IR22 infrared transmitter uses the adsorption spectra of gases for targeted monitoring of specific combustible gases and CO₂. The measurement method allows reliable monitoring even under difficult conditions, such as a low percentage of oxygen in the ambient air. Selective and insensitive Not only is the method highly selective, it is also extremely insensitive to sensor toxins and, unlike for example catalytic sensors, can monitor the concentration of combustible gases even when there is little or no oxygen in the gas mixture. Communicates analog...
