Biocompatible Pressure Sensors for various Applications

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. In addition, 6 individual coefficients are stored in the module, which allow software correction for pressure and temperature measurement by an external microprocessor.

The three sensors presented are all coated for biocompatibility and suitable for direct contact with bodily fluids; in the case of the IntraSense for 24 hours, in the case of the 1620 and MS5839 even for a full 7 days. AMSYS will present these and other sensors for medical products at Compamed in November in Düsseldorf, hall 8A, booth 8AM04. In addition, they are of course available via our homepage.
