LEL propane sensor MIPEX-05 PPM [C3H8]

NDIRinfraredfor leak detection

Overview
MIPEX-05 PPM [C3H8] is a high-performance NDIR gas sensor in a 4th series housing with 10 ppm resolution. It is a high-sensitivity, ultra-low power infrared sensor designed to detect propane (C3H8) at low concentrations (from ~30 ppm), enabling early leak detection and emission/health-safety monitoring. The sensor supports measurement in both ppm and LEL concentrations and is optimized for battery-powered portable detectors due to its very low power consumption.

Key features

• High-sensitivity version of an ultra-low power propane sensor
• 10 ppm resolution for hydrocarbons
• Detects propane from approximately 30 ppm (suitable for early leak detection)
• Low average power consumption enabling extended battery life in portable devices
• Suitable for emission monitoring and health & safety applications

ULTRA-LOW POWER CONSUMPTION
Average power consumption below 0.3 mW.

INTEGRATED MICROCONTROLLER
Returns linearized and temperature-compensated digital output via UART interface.

TECHNOLOGY
Simultaneous control of ppm and LEL concentrations. Dual-wavelength technology minimizes interference from water vapor and contamination, ensuring high measurement reliability.

Explosion-proof design
Intrinsically safe explosion protection level "ia" in compliance with IECEx, ATEX, UL913, CSA.

Standard 4th series size
Durable plastic housing Ø20.1 × 16.6 mm for easy integration.

LONG-TERM MEASUREMENT STABILITY
Designed for long-term measurement stability over 10 years.
