Pressure sensors are designed as PCBs for medical use

Differential pressure sensors, B58621V, have been designed as PCBs by TDK. The sensors are designed for measurement ranges of 16mbar full scale (FS), 100mbar FS and 7.0bar FS, with accuracy of up to ± one per cent FS at temperatures from -20 to +70 degrees C.

The sensors have a footprint of 24 x 26mm, making them suitable for pressure ports and inlets, where they allow for screw fitting and easy maintenance. Two plug connectors enable them to be used in daisy chain systems. The integrated serial peripheral interface (SPI) enables integration into various digital applications with ease, says TDK.

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. The low profile of just 6.0mm also makes them well suited for use as stationary and mobile ventilators. The sensors are also suitable for monitoring filters and gas admixtures.

TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK’s comprehensive portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high frequency and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. In addition, TDK provides power supplies and energy devices, and magnetic heads, with products marketed under the brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda.

TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
