GfG Instrumentation presents the new innovative IR 29 Transmitter for combustible gases; the first intrinsically safe infrared (IR) transmitter for Zone 0. There are two models; the IR 29i which is intrinsically safe for hydrocarbons (LEL) and the IR 29Di which also has the graphical display.
IR transmitters have become recognized as reliable gas warning systems for explosion protection. They are used to detect individual combustible gases or a wide range of gases. A special feature of the IR 29 technology is its ability to also measure combustible gases above the lower explosion limit. Moreover, the measurement does not require oxygen. With this technology there is basically no risk of contaminating the sensor.
The IR 29 is the first and only intrinsically safe IR gas transmitter with patented 4-beam 4-wavelength technology. The ignition protection class “intrinsically safe”, which is so essential for industrial plants and the mining industry, is achieved by the additional use of the SB1 safety barrier and its internationally patented and innovative design.
The IR 29 is the first IR gas transmitter that can also be used in Ex zone 0 and which enables maintenance as well as replacement of the sensor head without additional expense when energized.
A standard built-in data logger records all the measuring data, minimum/maximum values, average values and alarm events of the last 24 hours in a ring buffer. Measured values are shown on the high-contrast graphical display. Local displays and signals directly at the device can be used to provide an early warning of potential risks. The display at the upstream safety barrier SB1 D enables the detection of risks outside the danger zone being monitored.
