  Long-Term Stable Metal-Oxide Gas Sensor
  
  The long-term stable metal-oxide gas sensor SGP features multiple sensing elements on one chip providing in-depth information on air quality. The SGP is based on Sensirion’s multi-pixel platform, which integrates four gas sensing elements into a very small 2.45 x 2.45 x 0.9 mm³ DFN package featuring a fully calibrated air quality output signal. The unprecedented combination of long-term stability and multi-pixel technology opens up new possibilities for environmental monitoring in smart home, appliances and Internet of Things applications.

  Proximal Flow Sensor for Neonatal and Pediatric OEM Applications
  
  The SFM3400 flow sensor is a proximal flow sensor for neonatal and pediatric applications in respiratory devices such as ventilation or anesthesia. The sensor is available as both a single-use version (SFM3400-D) and a reusable version (SFM3400-AW) and features outstanding measurement accuracy and a short signal processing time as well as high robustness. It is fully calibrated for air, N₂ and O₂ gases and it measures bidirectional flow rates of up to 33 slm. Thanks to its performance characteristics, the SFM3400 mass flow meters are ideally suited for OEM applications in the area ventilation and anesthesia.

Mass Flow Meter SFM3100

Analog Flow Sensor for Respiratory Applications

The analog mass flow meter SFM3100 is highly accurate and fast. The SFM3100 has a compact design and can be easily integrated into existing devices. There is a temperature sensor in the gas channel of the flow meter. This enables highly precise temperature compensation and obviates the need to integrate a dedicated temperature sensor.

The SFM3100 measures flow ranges between -24 and +240 slm. It can also detect negative flow ranges, thereby recognizing errors or impeded flows in a reliable manner. At the same time, multiple gases are compensated with great precision. The flow rates and signal characteristics can be customized to meet customer-specific requirements.

Like all Sensirion sensors, the analog mass flow sensor is based on the patented CMOSens® Technology, which combines the sensor and analysis electronics on a single microchip. The result is a highly stable and precise system for demanding and cost-sensitive applications. The SFM3100 is particularly suitable for inspiration applications as well as for mixing oxygen and air to a very precise degree.
