Refrigerant detection sensor 'SGD43S-M3-S7'

The Sensirion refrigerant leak detection system "SGD43S-M3-Sx" has been certified by UL Solutions (UL60355-2-40). This allows us to provide our customers with a rational UL-certified sensor module that responds to the evolution of refrigerant regulations. The SGD43S-M3-Sx is specially designed as a complete refrigerant detection system (RDS) for the HVACR industry. It is based on the principle of thermal conductivity measurement and features dual relay contact outputs that activate signal relays to enable the startup of blowers, turn off loads, and send alerts to control panels. The status display LED provides quick visual feedback, facilitating easy integration and a user-friendly design for installers. "SGD43S-M3-S5" offers dual calibration in a single device to monitor R-454B and R-32 refrigerant leaks for HVAC applications. "SGD43S-M3-S7" provides triple calibration in a single device primarily for monitoring R-454A, R-454C, and R-455A refrigerant leaks in refrigeration applications.
