Advantages of our IRNEx-P 20mm NDIR sensors:

  • ATEX or IECEx certified, for use in classified areas
  • SIL2 rated, for certified dependability (fail-safe detection)
  • Individual calibration and testing, for measurements you can trust
  • Extended temperature range (-40 to +60 °C), for use in any environment
  • Internal microprocessor, for advanced signal processing
  • Standard industrial size, to fit existing detectors
  • Fast T90 response time, for critical and life-saving applications
  • ModBus or P2P digital communication, for ease of integration
  • Solid, rugged construction with stainless steel enclosure
  • Signal versatility: voltage and optional bridge or pellistor output
  • Patented, longer optical path for better resolution and stability
  • Standard industrial accepted negative or positive pinout

IRNEx-P 20mm is N.E.T. solution for whoever is looking for an ATEX or IECEx certified IR sensor with strong and dependable performances both at low and high volume. With a standard 4-series built, the low power version (45 mA) is perfect for a portable gas detector while the standard version fits smaller detection heads and compact detectors. Learn more about ATEX and IECEx standards in our Certifications section.

IRNEx-P 20mm detects CO2 or hydrocarbon gases such as propane and methane in LEL range. The 0-100%Vol range version features N.E.T. DYNAMIC technology for the highest sensing accuracy ever seen in a compact sensor.

DYNAMIC sensors also provide an optional digital output for Propane detection over 0-2.1% Vol range – the best option to detect different hydrocarbons using a cross-reference factor. DYNAMIC sensors are suited for instrument manufacturers that want to design Methane and Propane detectors in compliance with the Chinese Mine standard.

All N.E.T. IR sensors run on a microprocessor-based platform for internal signal processing, providing a linearized and temperature compensated output in digital and analogue format – the ideal solution for instrument manufacturers, even without any specialist knowledge in IR technology.
