Sensata’s RGD Series gas sensors provide OEMs and their customers the peace of mind that comes with no added maintenance for refrigerant leak detection.
These sensors have the longest lifetime and highest resiliency in high humidity, and condensation environments compared to other gas sensing technologies.

Sensata’s Resonix™ RGD sensors feature a unique, patented technology that measures the acoustic resonance of the surrounding air in real-time. Typically mounted near the evaporator coil, the sensors can trigger mitigation, such as a fan, when A2L gas is detected - venting it before it reaches unsafe levels.
