The DPS contain only a few active devices, such as a piezo-reflective poly-silicon thin-film measuring cell, a signal processing ASIC and a U / I or U / U converter.

The calibration takes place electronically, which means that the pressure transducers have a small overall error and are long-term stable. The hermetically sealed and completely vacuum-tight stainless steel thin-film measuring cell ensures high long-term durability and stability. The ASIC is a programmable precision CMOS ASIC with EEPROM data storage and analogue signal path, which is qualified for an extended working temperature range.
