Infrared NDIR Sensor
Overview
PST gas sensors are designed with patented nondispersive infrared technology for the detection and measurement of the presence of refrigerant gases. To meet the growing need for lower global warming potential (GWP) refrigerant gases, Dynament offers sensors for both flammable (A3, A2, A2L) and non-flammable (A1) refrigerants. The Dynament Platinum NDIR sensor has a twenty-year history of meeting and exceeding gas detection needs in the most challenging of environmental applications.
The Platinum series platform provides a linearized, high resolution measurement of refrigerant gases over the lower explosive limit range.
Sensor ranges:
R32 0-15% volume
R454B 0-12% volume
R454C 0-15% volume
R290 0-2% volume
R744 0-5% volume
R744 0-500 ppm
The 'Premier' Gas Sensor Configuration unit is for use with 'Platinum' Series sensors. It enables customisation of user definable parameters, data logging and calibration.
Modbus communications available
This product supports the industry-standard Modbus RTU protocol for easy integration, configuration, and diagnostics.
Dynament Infrared Platinum Sensors are used for the detection of refrigerant gases to ensure safe and efficient operation in various industries, including HVAC/R systems, refrigerated warehousing, and industrial refrigeration.
They use NDIR technology to detect and measure the presence of refrigerant gases, providing early warnings for the presence of flammable gases and enabling prompt action to prevent potential hazards.
The advanced sensing elements and signal processing algorithms in these sensors enhance their accuracy and sensitivity, thereby minimizing false alarms and ensuring precise measurements.
Fast response times enable real-time detection of refrigerant gases, allowing prompt intervention in the event of leaks or abnormal conditions, which helps prevent equipment damage and potential safety hazards.
Long-term stability ensures consistent performance over extended periods, reducing maintenance requirements and enhancing the overall lifespan of the sensors.
The sensors have successfully passed all performance tests conducted in an independent study by AHRTI, with full results available in the published report, "Refrigerant Detector Characteristics for Use in HVACR Equipment," March 2020.
Dynament Sensors are designed with enhanced EMC protection and fail-safe operation features, ensuring reliable performance even in challenging environments.
