Transmitter IR22 D

Product catalog summary

Overview: The IR22 D is an infrared transmitter designed for monitoring combustible gases and CO₂. It utilizes adsorption spectra for precise detection, even in low oxygen environments. The device is highly selective and resistant to sensor toxins, unlike catalytic sensors.

Communication: The IR22 D supports both analog (4-20 mA or 0.2-1 mA) and digital (RS-485) communication, allowing integration with GfG controllers and PLCs.

Design and Features: The transmitter is housed in a compact, splash-proof, and dust-resistant (IP54) casing. It features a 2.2" display with an integrated horn and status LEDs. The display shows gas type, unit, and current values, changing color in alarm situations. LEDs indicate operational readiness and special states.

Maintenance: The device 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 display and acoustic alarm for on-site value display.

Transmitter IR22 D with display and horn For monitoring combustible gases (HC) and CO₂ The IR22 D 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...
