Five Pressure Sensor Technologies
BD|SENSORS is the world leader in >> electronic pressure measurement technology for industrial applications when it comes to solution capability, flexibility, short development and delivery times as well as sustainability and continuity.
In order to live up to this claim, it is essential to be able to fall back on the optimum pressure sensor technology - both in terms of technology and price. This is why BD|SENSORS processes five pressure sensor technologies that have been newly developed or enhanced over the years.
Only this made it possible to develop more than 150 standard products and hundreds of customized devices in the nominal pressure ranges of
nominal pressure ranges from 0.1 mbar to 10,000 bar
and successfully place them on the market for all gaseous and liquid media encountered in practice. Particularly in >> hydrostatic level measurement technology, the liquid medium often places particularly high demands on the pressure sensor in terms of medium resistance, long-term stability and reliability.
Under these circumstances, the following conviction of our CEO Rainer Denndörfer is of utmost importance:
“What BD|SENSORS doesn't solve within electronic pressure measurement, no one else can solve.”

SILICON PRESSURE SENSORS
without media separation for low pressure | 200 mbar up to 7 bar relative pressure silicon, stainless steel 1.4404, glass, epoxy Ø 15.8 mm | The special design of the pressure sensor makes it suitable for measuring low pressures of non-aggressive gases and compressed air, as is usually the case in pneumatic applications. |
with media separation for low pressure | 200 mbar up to 7 bar relative pressure stainless steel 1.4435 Ø 15.8 mm | The universal pressure sensor with silicone oil filling can be used for gaseous and liquid media. Due to its very good long-term stability, this pressure sensor is often used in the field of hydrostatics, e.g. for level measurement. |
with media separation for medium pressure | 200 mbar up to 70 bar absolute and relative pressure stainless steel 1.4435 Ø 15.8 mm | In view of its outstanding performance, this pressure sensor is not only used for general and high-precision pressure measuring devices in machine, plant and test bench construction, but also in many other applications, such as hygienic pressure measuring devices for the food and pharmaceutical industries. |
with media separation for high pressure | 70 bar up to 700 bar absolute and relative pressure Edelstahl 1.4435 Ø 15.8 mm | The robust design of this pressure sensor enables applications in the high-pressure range in particular. Its stability and outstanding signal stability are impressive in a wide range of hydraulic applications. |

CERAMIC THICK FILM PRESSURE SENSORS
in flush design | 500 mbar up to 800 bar absolute and relative pressure ceramic Al2O3 96% Ø 15 mm / 18 mm | Thanks to the flush-mounted, ceramic diaphragm made of Al2O3 96%, the pressure sensor can be used for a wide range of applications - regardless of whether it is clean, contaminated or aggressive or corrosive gases or liquids. |
in monolithic design | 2 bar up to 400 bar relative pressure ceramic Al2O3 96% Ø 18 mm | The ceramic pressure sensor can be used for corrosive, aggressive and non-aggressive gases and liquids that are 96% compatible with ceramic. It also has an excellent price-performance ratio and is suitable for pressure measuring devices with high demand quantities. |
THIN-FILM PRESSURE SENSORS
4 bar up to 2,000 bar relative pressure stainless steel 1.4548 / 1.4435 Ø 8 mm / 10 mm | Thin-film pressure sensors have no filling liquid for pressure transmission and are welded. These are important prerequisites for use in technical gases, such as oxygen or hydrogen, as well as in hydraulic applications. |
.

FOIL STRAIN GAUGE PRESSURE SENSORS
350 bar up to 10.000 bar relative pressure stainless steel 1.4548 Ø 16 mm | Due to the high material requirements, foil strain gages are used for hydraulic applications (hydraulic test benches, high-pressure pumps, etc.) where, in addition to very high static pressures, high stability under dynamic pressure loads is also required. |
GROUP CAPACITIVE PRESSUR SENSORS

CAPACITIVE CERAMIC PRESSURE SENSORS
60 mbar up to 50 bar absolute and relative pressure ceramic Al2O3 99.9% Ø 19 mm / 32.4 mm | Due to the high-purity 99.9% ceramic, this ceramic pressure sensor is not only characterized by its outstanding media resistance to highly aggressive or corrosive gases or liquids, but is also ideal for various hydrostatic applications (e.g. drinking water, waste water, chemicals, etc.) thanks to its robust design and high overload. Due to the capacitive measuring method, it also has a high level of accuracy even at very low pressures or levels. |
