The SFM3300-D is Sensirion's single-use mass flow meter for gases. The product offers high accuracy, robustness and an extremely short signal processing time, according to the company. Developed for proximal flow measurement in medical applications such as ventilation or anesthesia, it is also suitable for other applications that require a disposable solution.
The digital SFM3300-D is accurate and robust, and has a short signal processing time. It is fully bidirectionally calibrated and measures flow rates up to 250 slm. The special design of the flow channel results in minimal dead space and the slightly increased pressure drop ensures very high stability in varying inlet conditions. Furthermore, the sensor can be connected via medical cones for the pneumatic connection to the respiratory cycle, and has a mechanical interface for a user-friendly electrical connection. Thanks to these features, the new mass flow meter is particularly suitable for proximal flow measurements in medical ventilation and other respiratory applications.
Like all Sensirion’s sensors, the new SFM3300-D flow sensor features the CMOSens technology, which allows the integration of sensor and signal processing circuitry on a single tiny CMOS silicon chip. The result is an ultra-precision system that offers long-term stability for sophisticated and cost-sensitive applications. In addition, the technology is also highly resistant to environmental influences.
The SFM3300-D mass flow meter completes Sensirion’s SFM3xxx platform for flow measurements, which now comprises six sensor products and covers all gas flow measurement in medical technology. The sensors can be used in a wide range of medical applications, such as inhalers, drug delivery and metabolic measurements. The SFM3000, SFM3100 and SFM3200 mass flow meters are suitable for inspiratory flow measurements; the SFM3200-AW, SFM3300-AW and SFM3300-D mass flow meters are an ideal choice for expiratory or proximal flow measurements.
Sensirion will launch other mass flow meters next year.
