Amphenol Advanced Sensors T3400 Series A2L Refrigerant Leak Detection Sensor
Telaire T3400 Series Refrigerant Leak Detection Sensors by Amphenol Advanced Sensors deliver precise and reliable monitoring of refrigerant gas leaks through advanced thermal conductivity technology. Using a micro thermal conductivity detector (micro TCD) sensing element, the sensors measure variations in gas mixture conductivity caused by refrigerant discharges. This approach provides an accurate and repeatable method of identifying leaks, ensuring dependable performance in demanding environments.
Unlike other detection technologies, the T3400 Series offers exceptional long-term stability, reduced maintenance requirements, and strong resilience against harsh operating conditions. Designed for integration into a wide range of HVAC, refrigeration, and environmental control systems, these sensors support early leak detection to improve safety, efficiency, and compliance with environmental regulations.
