DST G290 gas sensors for HVAC and Refrigeration systems
A3 gas detection made easy with the new DST G290 gas detection sensors by Danfoss Sensing Solutions, built with performance and reliability at the forefront.
DST G290 A3 refrigerant detection sensors
DST G290 A3 gas detection sensors with advanced photoacoustic technology are expertly engineered to meet the stringent requirements for A3 refrigerants, such as R290 (propane), perfect for HVAC&R applications where accuracy and reliability are required. Featuring a revolutionary inverted design, which protects the sensor in harsh environments, combined with dew point monitoring and highly selective technology specifically calibrated for R290 you can significantly reduce the risk of false alarms, enhancing the system's reliability.
Features and benefits
Competitive and robust design
Membrane protected from impurities by patented inverted design. Immune to dust, oil and water spray, UV resistant, robust to changes from thermal cycling stress and mechanical stress.
Compliance with IEC and ATEX legislations
IEC 60335-2-40 edition 7 is revised to HP system with A3 refrigerant use regarding the new F-gas regulation, certified by 3rd party laboratory. ATEX compliant signal relay.
Fast and Accurate Leak Detection
Compensated over full range of operating temperature, humidity and pressure ranges with fast response time <30sec and fast warm-up (6 secs).
Eliminate False Alarms
Dew point monitoring, highly selective technology tuned to R290, and acoustic decoupling minimizes risk of false alarms. Robustness towards rapid changes in temperature and humidity.
Immune to Poisoning
No performance degradation from exposure to other gases incl common household chemicals
No field calibration over system's lifetime
Permanent factory calibration. No field adjustments or re-zeroing during 15+ year life.
Minimize “Silent” Failures
Robust “full signal chain” diagnostics check for faults and integrity of signal chain.
Small & easy-fit system integration
Flexible hardware and software to customer’s application specifications.
Production in Europe
Resilient supply chain with localized supplier
