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. measuring ranges using the example of selected gases...

Always be on the safe side with the IR29 Universal application The IR29 with its robust V4A stainless steel housing has been designed to withstand the harshest environmental conditions. The application areas of the dust and water-protected structure range from production and storage areas to disposal sites, biogas plants, mines and oil rigs. Graphical display Measured values are shown on the high-contrast graphical display. The display can be rotated 180° depending on the installation of the IR29. 2.7 to 3.3 µm range. Air humidity therefore initially generates a measuring signal the same as...

Dust protection A gas permeable, water-repellent diaphragm protects the absorption space of the transmitter against dust. The additional impact protection made from robust V4A stainless steel prevents mechanical damage to the optical components. The diaphragm can be cleaned or replaced in a matter of minutes. ■ Suitability for zone 0 ■ The energised transmitter can be replaced in zone 0 ■ Patented 4-beam 4-wavelength technology ■ Temperature,moisture and pressure compensation possible for the first time ■ Graphical display ■ Permanent local status and functional display Remote controls The...
