IRNEx-PRO 20mm

ATEX & IECEx certified NDIR gas sensor for CO2, Methane, Propane and other Hydrocarbons

Advantages of our IRNEx-PRO 20mm NDIR sensors:

• ATEX or IECEx certified, for use in classified areas

• SIL2 rated, for certified dependability (fail-safe detection)

• IP54 rated, for use in underground mines

• 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-PRO 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-PRO 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.
