NDIR sensors enhance measurement of methane

The gas sensors developed by Mipex Technology utilise light emitters and photo detectors based on A2B4-A2B6 solid state alloys which guarantee high efficiency concerning the detection of hydrocarbons and carbon dioxide.

New standards are achieved by the combination of an LED with optimised spectrum, a signal processing algorithm, an optical chamber, a specially designed photo diode and an embedded temperature sensor including electronic components to process signals in the smallest of spaces.

Different measuring ranges are offered depending on requirements: from 0 up to 100 % LEL or even up to 100 Vol% for methane. The communication with the electronics is provided via UART interface. Additionally an analogue exit is available. Another feature of the gas sensors is the explosion protection according to the Ex ia I U / Ex ia IIC U. Gas sensors of the MIPEX-02 and MIPEX-03 series don’t require the additional use of sinter metal as explosion-proof protection.

They are ‘Ex’ certified under ATEX, IECEx and ETL and thus satisfy the highest industrial safety requirements. MIPEX alarm sensors are also available without explosion protection for the residential environment.

The NDIR sensors are offered in a standard size of 16.6 x 20 mm with metal or plastic housings, with a special version disposing of lateral openings available in order to reduce the reaction times to < 10 s.
The advanced Low Power design of the unique miniature IR gas sensors makes them ideal for solar or battery powered wireless applications.
