Transmitter IR29
Innovative transmitter for combustible gases
Measuring method

IR transmitters have become recognised as reliable gas warning systems for explosion protection.

They are used to detect individual combustible gases or a wide range of gases. This involves sending an IR beam with a certain light intensity through a measuring space and then capturing it with a detector. Parts of this beam are absorbed by, amongst other things, hydrocarbon molecules. The reduced light intensity of the beam is registered by beam detectors and converted into a signal as the existing gas concentration % LEL.
Internal data logger

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. The recording can also be shown on the display as a 2 and 8 hour trend indicator. The histogram mode can be selected as a permanent display of the measured values. These values are continuously updated.
Advantages

A special feature of our IR technology is its ability to also measure combustible gases above the bottom explosion limit (uniqueness). Moreover, the measurement does not require oxygen. With this technology there is basically no risk of contaminating the sensor, e.g. through silicone vapours or hydrogen sulphide when using catalytic combustion sensors.
