Hydrogen Sensor Technology for Industrial Safety: Meet N.E.T. at SENSOR CONVERGE 2026
N.E.T. will exhibit at SENSOR CONVERGE 2026, taking place May 5–7, 2026 at the Santa Clara Convention Center, CA.
Visit Booth 952 to explore MAK: The Intelligent Thermal Conductivity Gas Sensor, developed for Hydrogen detection in industrial applications.
As Hydrogen adoption expands across energy and industrial sectors, selecting the appropriate Hydrogen sensor technology becomes a critical design decision.
At SENSOR CONVERGE, N.E.T. will showcase its approach based on Thermal Conductivity (Katharometer) sensing implemented with MEMS technology.
Hydrogen monitoring in industrial systems
Hydrogen is increasingly used in:
- Electrolysis systems
- Storage and distribution infrastructure
- Refuelling stations
Due to its properties, high flammability, absence of odour, transparent flame and rapid dispersion, Hydrogen monitoring is required for safe operation.
In this context, Hydrogen detection is not only a compliance requirement, but a core element of system design, especially in applications where operating conditions vary or where maintenance access is limited.
What are the limits of conventional Hydrogen sensors?
Traditional technologies such as catalytic sensors (pellistors) and electrochemical sensors are widely used for Hydrogen detection, but present known limitations:
- The need for Oxygen to function
- Susceptibility to poisoning
- Performance degradation over time
- Need for regular maintenance
These constraints can limit their use in applications such as inert environments or systems requiring long-term stability.
Hydrogen has the highest Thermal Conductivity of all gases, making it particularly suitable for detection using this principle.
Thermal Conductivity, also known as a Katharometer, Hydrogen sensors offer:
- Operation without the presence of Oxygen
- Detection across a wide concentration range (ppm to 100% volume)
- Measurement based on a physical principle (no chemical reactions)
MAK sensors detect Hydrogen concentration in air by measuring the change in Thermal Conductivity of the Gas mixture.
The MAK sensor platform is designed for OEM integration and industrial applications, offering:
- Individual calibration and testing, for measurements you can trust
- Extended temperature range (-40 °C to +60 °C), for use in any environment
- Active Environmental compensation (Temperature, RH, Pressure)
- Internal microprocessor, for advanced signal processing
- Standard industrial size, to fit existing detectors
- Low power consumption
- Fast T90 response time (< 20 s), for critical and life-saving applications
- Outstanding long-term stability of 1 % F.S./year
- ModBus or P2P digital communication, for ease of integration
- Signal versatility: voltage and optional bridge or pellistor output
- Solid, rugged construction with stainless steel enclosure
- Standard industrial accepted negative or positive pinout
The sensor is compatible with existing detector architectures, including platforms originally developed for NDIR sensors, enabling integration without major redesign.
