Traditional optical sensors typically use miniature incandescent lamps as a radiation source, which are relatively inefficient. The MIPEX sensors use LED-based infrared sources, operating in an ultra-short pulse mode, which achieve significantly higher efficiency in converting electrical current into infrared radiation within the required spectral range. In addition, the sensors feature an optimised optical path, a high-sensitivity photodetector (up to 10× more sensitive than traditional pyroelectric detectors), advanced signal processing algorithms, and other proprietary technologies that enable ultra-low power consumption without compromising measurement performance.

The MIPEX sensor uses an optical design and spectral analysis method that minimises the effects of humidity on gas measurements. Like all optical sensors, MIPEX are sensitive to water — including condensation and droplets — which may lead to temporary signal drift and inaccurate readings until the moisture fully evaporates from the optical surfaces.

The MIPEX optical gas sensor is equipped with an integrated temperature compensation system. During abrupt temperature fluctuations, individual components of the sensor may respond at different rates, which can temporarily disrupt compensation accuracy. In such cases, the sensor will indicate a status alert showing a rapid temperature change, with a potential for temporary measurement inaccuracy.
When a temperature shift occurs in a high-humidity environment, condensation may form on the optical surfaces, resulting in temporary signal drift. This condition typically resolves once the condensation has fully evaporated.

The sensor measures gas concentration based on partial pressure, meaning its readings are directly proportional to the total ambient pressure. For example, if the sensor reads 2.0% vol. at 1.0 atm, the same gas mixture at 1.1 atm will read 2.2% vol.

Yes. MIPEX sensor calibration includes two steps: zero adjustment and span (scale) adjustment. Calibration is required during the initial integration of the sensor into a gas detection device, and also prior to system-level calibration of the equipment.

Zero adjustment should be performed in the following cases:

• Аfter long-term storage without power supply,
• Аfter transportation,
• Аfter installing or replacing a filter.

Scale (span) adjustment should be performed at least once every 36 months, depending on operating conditions and internal quality protocols.

Zero adjustment is required because the internal optical alignment may be affected by:

• Mechanical shocks during transportation,
• Light redistribution caused by filter installation,
• Natural signal drift during long-term storage without power.
• These factors can lead to a shift in the signal baseline, requiring manual correction. While in operation, the sensor’s internal algorithm performs automatic zero correction, but initial manual calibration ensures optimal accuracy.

A replaceable dust filter is recommended to prevent contamination of the optical surfaces, which may lead to a reduction in signal quality below acceptable thresholds.
In cases where the gas analyser is already equipped with an integrated filter, the use of an additional dust filter is not required, as it may reduce the sensor’s response speed.
