- Solution is the first with full UL Recognition for the use of
R454A, R454B, R454C, and R32 under the 4th edition of UL
60335-2-40
- Sensata Resonix™ RGD Sensor detects the presence of A2L
refrigerant gases by monitoring the acoustic resonance of the
surrounding air.
- Unique, patented technology provides HVAC manufacturers with an
ideal approach to meet new global warming-related regulations.
Sensata Technologies (NYSE: ST), today announced the launch of
the Sensata Resonix™ RGD sensor, the first leak detection sensor
with UL certification for multiple A2L refrigerant gases used in
heating, ventilation, and air conditioning (HVAC) equipment. The
new leak detection sensors support HVAC manufacturers’ transition
to refrigerants with a lower global warming impact.

Sensata’s Resonix™ RGD sensors leverage patented gas detection
technology to meet the needs of HVAC manufacturers using new
hydrofluoroolefin (HFO) refrigerants as part of a global shift away
from hydro-fluorocarbon (HFC) refrigerants.
HFC gases have been widely used in air conditioning and
refrigeration equipment for decades due to their performance
characteristics. However, HFC gases have a high global warming
potential (GWP) – often hundreds of times more potent than carbon
dioxide (CO2). This issue was the driving factor behind the recent
Kigali Amendment to the Montreal Protocol, which targets an 85
percent reduction in HFCs in the United States and other developed
countries by 2036, and globally by 2047.
While HFOs have a far lower GWP, they are classified as slightly
flammable (A2L categorization), and new leak detection design
requirements mandate mitigation features to prevent a potential gas
buildup.
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.
The RGD series received full certification for R32, R454A,
R454B, and R454C refrigerants under UL 60335-2-40 Edition 4, with
fully certified test results – critical evidence for OEMs facing
tight regulatory timelines. The sensor also received recognition
under UL 60335-2-40 Edition 3.
The sensors deliver a fast response time with a life expectancy
of more than 15 years – often exceeding the lifetime of the
equipment itself. Because the sensors do not require field
calibration or re-zeroing, they reduce service costs for both
installers and end users. They are also unaffected by fouling
gases, HVAC cleaning solutions, and continuous refrigerant
exposure.
“Sensata’s Resonix™ RGD sensors deliver a reliable, robust, and
resilient gas detection solution for our customers that will be
with them for the life of their equipment,” says Alice Martins,
Vice President for Sensata’s Industrial Solutions. “Our work in
helping our customers reduce HFC use worldwide is another way that
Sensata is innovating for sustainability and helping confront
global warming.”
