Analog mass flow meter for artificial respiration and anesthesia

At COMPAMED 2014, the Swiss sensor manufacturer Sensirion will launch its SFM3100 analog mass flow meter for applications in medical respiration and anesthesia. The new sensor has an impressively small design and delivers high accuracy and fast response times.

Sensirion is an expert in medical technology. The high-quality sensor solutions from the Swiss company have been used in artificial respiration and anesthesia for many years and provides maximum precision and reliability. With the new SFM3100, Sensirion is offering a mass flow meter that fulfills varying respiration requirements in emergency care, intensive care medicine and home care even better than before. It is suitable for inspiration applications as well as for mixing oxygen and air to a very precise degree. The SFM3100 has already proven its suitability in several devices on the market.

The new SFM3100 measures with great accuracy and speed. It 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. Moreover, the SFM3100 returns an analog output signal and measures the flow rates of air and other non-aggressive gases 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 of the sensor can be customized to meet customer-specific requirements. The fully calibrated and temperature-compensated mass flow meter also boats an extremely low pressure drop and is free of zero-point drift.

Like all Sensirion sensors, the SFM3100 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 therefore perfect for safe and reliable applications.

Sensirion will present the new sensor product at COMPAMED 2014 in Düsseldorf. Visit us at our stand H19.6 in Hall 8a from 12-14 November to learn more about the innovative SFM3100 mass flow meter.
