TDK Corporation announced the launch of a new range of differential pressure sensors designed as printed circuit boards for use in medical devices. The sensors are designed for measurement ranges of 16 mbar full-scale (FS), 100 mbar FS and 7 bar FS, with accuracy of up to ±1% FS at temperatures from -20 °C to +70 °C.
Their footprint of 24 mm x 26 mm accommodates pressure ports and inlets as well as two plug connectors for implementation of daisy chain systems. The integrated SPI (serial peripheral interface) enables integration into various digital applications.
The sensors are EN ISO 13485-certified for use in medical devices. Precise pressure loss measurements in the flow lines allow flow rates to be calculated accurately in ventilator equipment, and they are particularly well suited for mobile ventilators due to their extremely low profile of only 6 mm, according to TDK. The sensors are also suitable for monitoring filters and gas admixtures.
