Gas Sensors Head

The gas sensor head is the front-end component that directly detects the target gas.
It contains the gas-sensitive element (sensor) that reacts to the presence of a specific gas — such as oxygen (O₂), carbon monoxide (CO), methane (CH₄), or hydrogen sulfide (H₂S).

In many designs, the sensor head is replaceable — meaning you can keep the same detector body and just swap the sensor head when:

The sensing element expires (typical lifespan: 2–3 years)
You want to monitor a different gas type

This modular setup makes maintenance and calibration easier.

Gas Sensor Head and Fixed Gas Detector

The gas sensor head is the core sensing part inside a fixed gas detector.
Without the sensor head, the detector cannot “smell” or identify gases.
The fixed gas detector provides the housing, electronics, and communication needed to make the sensor’s signal useful and safe.

How a Gas Sensor Head Works

A gas sensor head is the primary sensing element in a gas detection system. It detects specific gas concentrations in the air and sends signals to a control unit or gas detector panel for real-time monitoring. Gas sensor heads are used in various industries to ensure safety, prevent hazardous gas leaks, and comply with environmental regulations.

Gas sensor heads contain specialized sensors that react to the presence of specific gases. When the gas concentration reaches a certain level, the sensor generates an electrical signal that triggers alarms, ventilation, or shutdown systems.

Electrochemical Sensors

Detect toxic gases such as carbon monoxide (CO), hydrogen sulfide (H₂S), and chlorine (Cl₂).

Infrared (IR) Sensors

Used for detecting gases like carbon dioxide (CO₂), methane (CH₄), and hydrocarbons.

Catalytic Bead Sensors

Measure combustible gases such as propane, butane, and hydrogen.

Photoionization Detectors (PID)

Detect volatile organic compounds (VOCs) and hazardous chemicals.

Semiconductor Sensors

Respond to gases like ammonia (NH₃) and refrigerants.
