MIPEX-05
NDIR Gas Sensor

The MIPEX-05 ultra-low power infrared gas sensor has LED based differential dual wavelength technology that allows for the elimination of water vapor, optical elements contamination and other non-selective hindrances influence. It is intended for automatic continuous measurement of the concentration of hydrocarbons in the atmosphere of hazardous areas. The sensor is used as an OEM component for portable fixed gas detectors for industrial safety. The sensor’s operating principle is based on NDIR technology, that is on selective absorption of infrared radiation by gas molecules.

Features:

  • Ultra-low power consumption. Average current consumption at constant measurement of concentration is less than 50 μA. (microAmp)
  • Smart sensor with embedded microcontroller returns linearized, temperature-compensated output data.
  • LED based dual wavelength technology.
  • Response time (T90) without dust filter 10 sec for methane, propane, ethane.
  • Provides intrinsically safe explosion protection level “ia”.
  • Industry standard size (⌀20.3×16.6 mm).

Measurement range

  • up to 100% vol. for methane (CH4)
  • up to 2.5% vol. for propane (C3H8)
