Long-Term Stability, Sensitivity, and Reliability
Our sensors achieve long-term stability, precision, and reliability that are unparalleled on the market. These characteristics are crucial in medical applications, and are fundamental to your and your products’ success.
Economy of Scale
As a standard process for semiconductor manufacturing, CMOS has been optimized for reliable mass production. Through their high-volume production, sensors using CMOSens® technology based on this standard process enable optimum cost-effectiveness – naturally without compromising reliability nor precision.
The SFM3100 analog mass flow meter is highly accurate and fast. It has a compact design and can be easily integrated into an existing system. An integrated temperature sensor eliminates the need to install an additional sensor. The SFM3100 can also detect negative flow ranges, thereby recognizing errors or impeded flows.
The autoclavable SFM3300-AW mass flow meter can be used for bidirectional measurements. Because of the small dead-space volume and the stability against different inlet conditions, the reusable product is particularly suitable for proximal flow measurements.
The SFM4100 flow meter with its wide dynamic measuring range has been developed for integration in anesthetic equipment. The excellent long-term stability and freedom from drift make the SFM4100 the first choice for products with a high usage rate and at the same time long service intervals.
Mass Flow Controller SFC5000
The SFC5000 series enables very fast, precise, and repeatable measurement and control of mass flow over a wide dynamic measuring range. The mass flow controller with digital and analog interfaces features a multigas option, gas recognition, and self-test capability.

The new SHT3x humidity and temperature sensor series takes sensor technology to a new level with unmatched sensor performance, range of variants, and new features. Suitable for a wide variety of markets, such as home appliances, medical, IoT, HVAC, or industrial. Also available in automotive grade.
The disposable LD20 flow sensors for biomedical applications measure flow rates within a range of 0–10 ml/min. The cost-effective sensors are especially suitable for medical applications. The use in an infusion set, for example, enables safer and more reliable treatment of patients.
The LPG10 OEM flow sensor on a surface of just 10 × 10 mm offers a smart sensor solution for flow rates of only a few microliters per minute to up to 1 ml/min. Thanks to Sensirion’s unique CMOSens® technology with planar microfluidic substrates, the LPG10 flow meter is cost-effective and provides accurate measurements combined with very short response times.
The incredibly small LPP10 flow meter measures flow rates from nl/min. up to 20 ml/min. and is suitable for various applications requiring precise flow measurements in the smallest spaces. The LPP10 flow meter is extremely cost-effective thanks to its innovative concept, and can be adjusted for larger quantities to individual customer requirements in the context of specific projects.
The fully calibrated and temperature compensated differential pressure sensors of the SDP3x series provide a fast and reliable sensor signal with no zero-point drift. Their minimal size of just 5mm x 8mm x 5mm opens up new dimensions of integration and application possibilities in medical technology.
The digital products of the SDP600 series measure even minimal pressure differences with extremely high sensitivity and precision. The sensors are free from drift issues and are characterized by outstanding repeatability.
The analog differential pressure sensors of the SDPx108 series have been developed for airflow measurements in medical applications. Their outstanding sensitivity, accuracy, stability, and fast response times make the sensors a perfect solution for respiratory devices.
Sensirion sensor + Fraunhofer micropump = A miniaturized smart drug delivery module
Sensirion and the Fraunhofer Research Institution for Microsystems and Solid State Technologies (EMFT) is presenting an innovative concept study in the field of medical technology.
Fraunhofer EMFT’s silicon micropump has been combined with Sensirion’s LD20 disposable liquid flow sensor as part of a joint project with the aim of developing a smart and cost-efficient miniaturized module for controlled and monitored drug delivery. This highly integrated single-use drug delivery module measures a mere 35 x 15 x 5 mm3.
Efficient Gas Flow Measurements in Bypass
Measuring gas flow in applications requiring high precision and cost-efficiency is a challenge. Experience in recent years has shown that microthermal flow sensors are superior to other technologies. Industries with exacting demands, such as automotive and medical technology, have recognized that microthermal gas flow sensors give their products decisive advantages. These manifest themselves in high long-term stability and precision even when flow rates are minimal, and the sensors’ suitability for cost-efficient and reliable mass production.
Autoclavable Sensors for Medical Applications
Sensirion has been developing and marketing flow metering sensors for many years. Until now, these sensors have been used in ventilation and anesthetic devices to measure the volume of clean air administered to the patient. But apart from this clean tract, both ventilation and anesthetic procedures need a means of metering the flow of exhaled air. This is known as either proximal or expiratory flow metering. In both cases, the sensor comes into contact with air from the patient that is potentially infected with germs and pathogens. These sections of the apparatus are therefore comprised of disposable parts or hygienically sterilizable. Now Sensirion has developed new flow metering devices that are autoclavable and can be washed.
Infusion pumps that sense the drug flow - and even your heartbeat in it
Everyday millions of patients worldwide receive intravenous infusion therapy, many times assisted by a smart infusion pump. Smart infusion pumps provide well-controlled drug delivery over a prolonged period of time and are of tremendous help for hospital staff. However, they fall short when it comes to reliable failure detection. Today’s infusion pumps lack the technology to directly measure the flow rate of the drug inside the tubing which results in two main problems: First, there are failures that remain undetected and, second, over-sensitive pumps generate a high number of false alarms.
Typical failures during infusion therapy include occlusion, air-in-line, free flow, cross-flow in multi-infusion settings, and infiltration or extravasation. While all of the above failure modes are very well known to hospital staff, today’s infusion pumps can at best only detect the first three. Sensirion’s liquid flow sensing technology enables smart infusion pumps to detect not only these failures, but also reverse flow, cross-flow and even infiltration errors reliably.
