NDIR Refrigerant Sensor
Semiconductor Refrigerant Sensor
Technical Comparison of Semiconductor (Metal Oxide) vs. Infrared (NDIR) Refrigerant Sensors
| Feature | Semiconductor (Metal Oxide) Sensors | Infrared (NDIR) Sensors |
|---|---|---|
| Working Principle | React to refrigerant gas by altering the conductivity of a metal oxide surface. | Use Non-Dispersive Infrared (NDIR) absorption to detect specific gas wavelengths. |
| Pros | – Cost-effective – Compact design – Quick response to basic gas detection | – High accuracy – Long operational life – Specific to target refrigerants (low cross-sensitivity) |
| Cons | – Susceptible to cross-sensitivity (false readings from other gases) – Affected by humidity | – Higher initial cost – Slower response time – Larger physical footprint |
| Ideal For | Budget-sensitive applications, simple leakage alarms, or non-critical environments | Precision-driven systems, industrial monitoring, or applications requiring high reliability |
