NDIR Technology: Principles and Implementation in Gas Sensing

The operating principle, operational advantages, and application of Non-Dispersive Infrared (NDIR) Sensors. Infrared (IR) sensors detect Gas concentrations by measuring the absorption of infrared light at specific wavelengths. An infrared light beam passes through the Gas and reaches the collecting optics, which splits the beam and directs it through filters onto the IR detectors. The Operating Principle of NDIR Sensors The operating principle...

Hydrogen Monitoring: Achieving Integrated Safety with the new MAK sensors

Hydrogen is regarded as the future of clean energy, but its use requires high safety standards. As a highly flammable, odourless gas with an extremely high dispersion rate, constant monitoring is not only an operational necessity but also a critical requirement for every infrastructure, from electrolyzers to refuelling stations. In this scenario, traditional detection technologies, such as pellistors and electrochemical cells,...

Understanding ATEX Directives: Workplace and Equipment Safety Standards

What does ATEX stand for? The term ATEX is derived from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles. It encompasses two European Directives that establish minimum safety requirements for equipment and workplaces within explosive atmospheres.   What are the two primary ATEX Directives? ATEX legislation is divided into two specific areas of responsibility:   Directive 1999/92/EC (Workplace Directive):...

Meet the Most Reliable Refrigerant Gas Sensor on the Market — IREF PRO by N.E.T.

MOS (Metal-Oxide-Semiconductor) sensors have been the main go-to solution for detecting flammable Gas and refrigerant leaks for decades. Despite their affordability, MOS sensors come with significant trade-offs: frequent recalibration (every 6 months or less), short lifespan (2–4 years), and susceptibility to false alarms and environmental changes. IREF PRO by N.E.T. paved the way for the next generation of NDIR refrigerant Gas Sensors,...

NET NDIR SENSOR WARM-UP TIME: FULL OPERATION vs. FULL SPECIFICATIONS

NET NDIR SENSORS WARMUP TIME: FULL OPERATION vs. FULL SPECIFICATIONS The Data Sheet and User Manual for all our NIDR sensors states that warm-up time is 60 seconds for full operation at 25 °C and at least 30 min for full specifications. We are often asked what is the difference between these two conditions. At power-up the sensor performs initial “bootstrap”...

CATALYTIC BEAD SENSORS – POISONS AND INHIBITORS

A Pellistor, or catalytic bead sensor, monitors the presence of a combustible gas or vapor in air (or atmospheres containing oxygen) up to the Lower Flammable Limit (LFL). A Pellistor operates on the principle that when a combustible gas/air mixture is in contact with the catalyst surface, maintained at about 500°C as current is passed through it in a Platinum...
