Sensor Technologies for Gas Detection and Measurement Systems

Sensor Technologies for Gas Detection & Measurement Systems

We review infrared (NDIR), catalytic (pellistor), electrochemical, semiconductor and MPS (MEMS-based) sensor technologies used in gas detection from an engineering perspective. Which sensor suits which gases? What do ppm, %Vol and %LEL measurements mean? How should sensors be compared in terms of accuracy, response time, lifetime, maintenance and calibration?

The Key Element of the Clean Energy Future: Hydrogen and Its Safe Use

As hydrogen emerges as a critical component of the clean energy future, unique safety requirements arise across production, storage, transportation and industrial use. In this article, we examine hydrogen’s strategic role in energy systems, its wide range of applications, and the safety challenges throughout its lifecycle — and we explore modern safety solutions needed for a safe hydrogen infrastructure.

Hydrogen Gas Monitoring in Battery Rooms (Hydrogen Level Control to Prevent Explosions)

Battery rooms carry an explosion risk due to hydrogen released during charging. Learn how hydrogen sensors can help maintain safety in your facility by providing early warning and actionable control.

What Are Grade 1, 2, 3 and 4 Intruder Alarm Systems?

If you take security seriously as a business owner, you should choose an intruder alarm system that matches your risk level. Selecting the right grade is critical for protecting staff, property, stock and valuables — and for meeting insurance requirements.

Why Torque Calculation Matters for Pan-Tilt Motor Loads

Pan-tilt motors rotate mounted loads on the horizontal (pan) and vertical (tilt) axes. Torque calculation is a key factor for ensuring the motor can carry and move the load smoothly. If torque is not calculated correctly, overload, motor failures or unstable motion may occur.

What Are Fail Secure and Fail Safe?

Use Cases and Why They Matter for Security

Common CCTV Lens Terms and What They Mean

CCTV lens basics: F-stop, MOD, focal length and more.

How to Choose the Right CCTV Monitor Size

Which CCTV monitor size is ideal depending on viewing distance?

What Is an Interlock Access Control System?

An interlock system is a solution that decides whether a door can open based on the open/closed or locked status of one or more other doors.

SF6 Gas Leak Monitoring in High Voltage Facilities and Required Precautions

SF6 (sulphur hexafluoride) is odourless and heavier than air, so it can accumulate in low areas of gas-insulated switchgear if leakage occurs.

What Is NTP?

In our article, you’ll find key concepts related to the Network Time Protocol and get a brief introduction to NTP systems.

Carbon Monoxide Detector Applications in Enclosed Car Parks

With industrial carbon monoxide detectors offered by Furkan Engineering, if CO reaches dangerous levels in enclosed car parks, jet-fans or ventilation can be automatically activated to remove contaminated air and maintain healthier air quality.

Gas detector mounting height by gas density and LEL table

Gas Detector Mounting Height by Gas Density (Air = 1) and LEL Table

In fixed gas detection systems, installing the sensor at the correct height is as critical as choosing the right sensor. A gas’s relative density compared to air (Air = 1) helps predict whether it tends to accumulate higher or lower during a leak.
