Technology
Dual-wavelength, dual-beam LED-based infrared absorption method.
OPTICAL HEATING FUNCTION
Prevents condensation and ensures stable operation in high-humidity environments.
MEASUREMENT RANGE
Up to 1.7% vol. for propane (C₃H₈) by diffusion.
INTRINSIC SAFETY
Sensor is designed in compliance with: IECEx, ATEX, UL913, CSA.
LIFE TIME
More than 10 years of continuous 24/7 operation.
COMMUNICATION INTERFACE
UART, optional RS-485 (MODBUS).

Technical specifications

The MIPEX 1F is a high-performance optical gas sensor designed for stationary gas detection systems.

It provides continuous propane (C₃H₈) monitoring in hazardous areas by diffusion, ensuring exceptional accuracy and long-term stability.

An optional heating function prevents condensation on optical surfaces, enabling reliable operation even in high-humidity or subzero environments.


ADVANTAGES:

  • Ultra-low power consumption: < 2 mW. Suitable for autonomous and energy-efficient systems.
  • Low pulse current: < 5mA. Compatible with passive 4–20 mA current loops.
  • 4-wavelength NDIR technology: maintains high accuracy across a wide temperature range from –60 °C to +75 °C.
  • Optical heating system: prevents moisture build-up on sensing elements.
