Sensirion - The sensor company

Sensirion is a leading Swiss high-tech sensor manufacturer with headquarters in Staefa near Zurich and sales offices in the US, Germany, Japan, South Korea, China, Taiwan and Germany. The highly skilled team of over 600 employees develops and produces CMOS-based sensor components and systems for a wide variety of medical and other demanding OEM applications. The range of high-quality products includes humidity and temperature sensors, gas flow sensors and liquid flow sensors.

Customised sensor solutions for the medical industry

Sensirion is a reliable partner for the global OEM industry, providing millions of sensors each year. Beside standard sensor solutions, Sensirion offers customer-specific solutions. Therefore the existing standards are modified or completely redesigned on request. As a result perfectly suitable products for the medical market are available: the high-sensitivity liquid flow sensors are designed for measuring ultra-low flow rates e.g. in biomedical applications. Recently disposable liquid flow sensors are available and are suited for many different applications like drug delivery, implants or catheters. Sensirion's mass flow meters for gases are especially appropriate for respiratory devices. Due to their dynamic flow measurement principle, the digital and analogue differential pressure sensors offer superb long-term stability, and achieve superior accuracy and sensitivity even at low differential pressures (below 0.1 Pa). This makes them perfectly fit for the use as flow sensors in anesthesia equipment and medical ventilators. For the control of an ambient atmosphere, Sensirion provides humidity and temperature sensors characterized by excellent performance and low power consumption. Thereby Sensirion's sensor solutions help to increase the safety and reliability of medical devices.

Sensirion's innovative technology

Sensirion owes its success to its innovative and patented CMOSens® Technology. This technology integrates sensor elements and evaluation circuitry within a single semiconductor chip. This combination ensures that the weak sensor signals can be amplified and digitised with high precision directly where they are generated, thereby making them resistant to interferences. This provides the basis for the extremely high measurement accuracy of Sensirion's sensors. With the elimination of fault-prone solder joints, users also gain from outstanding long-term stability, as has been proven by extensive field tests. In the highly competitive medical market, this system integration offers unbeatable customer benefits, in particular its high reliability and precision at low cost.

ISO certifications

The reliable delivery of impeccable products is the fundamental prerequisite to achieving high customer satisfaction. To address the ever stricter specifications, we continuously improve and refine our quality management system. An important step in this process was the company's certification to the ISO/TS 16949 standard in March 2008. This enhances and supplements the previous certification to the ISO 9001 standard. The ISO certifications of our quality management system are a reflection of our ongoing efforts to design processes that achieve the highest possible customer satisfaction and to maximise the support of our customers' value-added processes. As well as its decided quality approach, Sensirion works on the continuous improvement of its environmental performance. Main goals are the permanent increase of energy efficiency, the safe handling of chemicals, and the absence of restricted or hazardous materials - making our production more sustainable. As evidence of this policy, Sensirion was certified according to the environmental ISO 14001 standard in March 2011.

Sensirion's newest products

Disposable Liquid Flow Sensor for biomedical applications

The new disposable liquid flow sensor series LD20 offers fast, precise and reliable measurement of low and ultra-low flow rates. The intelligent, compact and cost-effective sensors are suitable for a wide range of applications in the biomedical field, from controlling the flow of precious ingredients in bioreactors to monitoring infusion therapies in a clinical environment. www.sensirion.com/LD20

The world's smallest flow sensor - creating space for your ideas

The SDP3x is the world's smallest differential pressure sensor. It measures just 8mm x 5mm x 5mm, opening up new dimensions of integration and application possibilities. The SDP3x sensor is reflow solderable, provides extended functionality, such as multiple I2C addresses and interrupts and a fast sampling time. It features excellent accuracy and long-term stability and has no zero-point drift. All this makes the new differential pressure sensor of the SDP3x series the perfect choice for high-volume and cost-sensitive applications, where small size is essential. www.sensirion.com/sdp3x

Autoclavable mass flow meters for expiratory and proximal flow measurements

Sensirion new mass flow meters SFM3200-AW and SFM3300-AW are suitable for repeated, inter-patient use thanks to their multi-cycle, autoclavable and washable properties which allow them to be sterilised. The sensors are particularly well-suited for expiratory and proximal applications in medical ventilation and anesthesia. Both sensors are characterised by high measurement accuracy, superior exceptional robustness and a very fast signal processing time. www.sensirion.com/aw-sensors
