AMSYS GmbH & Co. KG, Mainz, July 2022 –As a specialist for sensor technology in the medical field, the German company AMSYS offers biocompatible pressure sensors in various designs for a wide range of applications, including the IntraSense, probably the smallest absolute pressure sensor for in-vivo use in catheters.
The IntraSense pressure sensor, which is only 220 µm wide, fits into the smallest 1 French catheters. With its wide pressure range of -300..500 mmHg, it can measure blood pressure as well as intracranial or bladder pressure quickly and directly on site. For rapid initial development steps, AMSYS also offers an evaluation kit with USB connection and software for initial measurements of pressure and temperature for prototyping.
With the 1620, AMSYS also has a relative pressure sensor in its portfolio that was developed for one-time use, e.g. in dialysis machines or oxygenators. These low-cost sensors cover the pressure range up to 300 mmHg typical for medical applications. Just like the other pressure sensors presented, it can be sterilized with ETO.
The small barometric sensor MS5839 with a footprint of only 3.3 x 3.3 mm² is universally applicable and with its biocompatible gel can also be used in anesthesiology, for example. Via its I²C interface, the MS5839 delivers the measured pressure and temperature signal with high precision and 24 bits.
The three sensors presented are all coated for biocompatibility and suitable for direct contact with bodily fluids. AMSYS will present these and other sensors for medical products at Compamed / Medica in hall 8A at booth 8AM04.
