NDIR propane sensor MIPEX-05 [C3H8]

for leak detectionfor air quality monitoringfor industrial gas safety monitoring

Overview: MIPEX-05 C₃H₈ is an ultra-low power infrared gas sensor designed for accurate detection of propane concentrations in explosive atmospheres. It is ideal for integration into portable and fixed gas detectors operating in harsh industrial conditions.

Performance: The significantly reduced power consumption of MIPEX-05 (less than 0.2 mW) makes it ideal for integration into portable gas detectors and wireless safety systems designed for long-term monitoring of propane concentrations in explosive atmospheres.

Features:
- Ultra-low power consumption: Average power consumption less than 0.2 mW.
- Integrated microcontroller: Delivers linearized and temperature-compensated digital output.
- NDIR Technology: Sensor operating principle is based on NDIR technology, using a dual-wavelength method to compensate for water vapor, dust, and optical contamination.
- Explosion-proof design: Sensor is designed in compliance with: IECEx, ATEX, UL913, CSA.
- Standard 4th series size: Durable plastic housing Ø20.1 × 16.6 mm for easy integration.

Advantages: 
- Ultra-low power consumption: less than 0.2 mW (average current < 60 μA) 
- Measurement range: 0–2.5% vol and 0–20% vol (C₃H₈) 
- Operating temperature: -40 to 60C
