With the new C32 series, EPCOS offers a compact, accurate and flexible pressure sensor in chip technology. Measuring 1.6x1.6mm2, they are designed for pressure ranges from 1 to 40bar. This makes them suitable for applications in automotive, industrial and medical electronics where miniaturization is important.
The nonlinearity of the C32 sensors is 0.3%FS. The chip also has high cyclic stability with drifts of 0.1%FS under temperature stress and this makes these sensors suitable basic elements for accurate and stable transmitter systems.
The chips are equipped with optimized bond pads which have spatially offset test-pad structures for wafer probers. The C32 variant allows glass pre-packaging at chip level on both the top and bottom of the chip. The glass package on the underside allows low-stress processing of the chips with bond and adhesive techniques for absolute and differential pressure applications. The reference volume for absolute pressure measurements is formed by an additional glass substrate on the top side of the chip. These measurements are consequently also possible in non-aggressive liquids and gases.
