How Organizations Deploy Industrial Gas Sensors
Gas Detection Sensor Frequently Asked Questions
Identify target gases and measurement ranges (ppm vs. percent volume). Consider operating temperature, humidity and interferent gases in your application environment.
Evaluate sensor format for equipment housing constraints, mounting configuration and electrical interface (analog vs. digital). Match response time and accuracy to instrument requirements.
Select technology by gas type:
- Electrochemical for toxic gases.
- Catalytic bead for combustibles.
- NDIR for hydrocarbons.
- PID for VOCs.
Consider sensor life and replacement cycles for your maintenance model. Our technical support team can provide application-specific guidance to help configure sensors matching your exact requirements and compliance obligations.
Sensor selection depends on target gas, required detection limits, environmental conditions and maintenance preferences. Many applications benefit from multi-technology approaches that combine these methods for comprehensive coverage.
- Electrochemical sensors excel at detecting toxic gases (CO, H₂S, NH₃, Cl₂) at ppm levels with low power consumption and compact design.
- Catalytic bead sensors provide reliable combustible gas detection with high poison resistance.
- Infrared (NDIR) sensors offer resistance to common catalyst poisons and fast response for hydrocarbons and CO₂.
- Photoionization detectors (PID) deliver parts per billion sensitivity for volatile organic compounds.
