Pressure sensors – technologies
The requirements of the job for pressure and level measuring devices are multifarious and, in addition to intelligent design solutions, require most of all appropriate sensor technology
Overview of our pressure sensors
| PIEZORESISTIVE STAINLESS STEEL SILICON SENSORS |
NOMINAL PRESSURES | APPLICATIONS |
|---|---|---|
| WITHOUT MEDIA ISOLATION FOR LOW PRESSURE Type DSP 210 (Ø = 18 mm) Type DSP 220 (Ø = 15,8 mm) |
20 mbar up to 7 bar | in OEM and industry devices for non-aggressive
gases and compressed air |
| WITH MEDIA ISOLATION FOR LOW PRESSURE Type DSP 410 (Ø = 18 mm) Type DSP 411 (Ø = 15,8 mm) |
100 mbar up to 7 bar | universally applicable in industry and precision devices for
gaseous and liquid media that are compatible with stainless steel |
| WITH MEDIA ISOLATION FOR MEDIUM PRESSURE Type DSP 411 (Ø = 18 mm) Type DSP 421 (Ø = 15,8 mm) |
350 mbar up to 35 bar | universally applicable in industry and precision devices for
gaseous and liquid media that are compatible with stainless steel |
| WITH MEDIA ISOLATION FOR HIGH PRESSURE Type DSP 412 (Ø = 18 mm) Type DSP 414 (Ø = 15,8 mm) |
70 bar up to 350 bar 70 bar up to 700 bar |
universally applicable in industry and precision devices for
gaseous and liquid media that are compatible with stainless steel |
| PIEZORESISTIVE CERAMIC THICKFILM SENSORS | NOMINAL PRESSURES | APPLICATIONS |
|---|---|---|
| IN FLUSH DESIGN Type DSK 519 (Ø = 32,4 mm) Type DSK 511 (Ø = 18 mm) Type DSK 516 (Ø = 15 mm) |
250 mbar up to 2 bar 500 mbar up to 800 bar 500 mbar up to 50 bar |
in OEM and industrial devices designed for aggressive media,
also with flush-fit membrane for viscous and dirty media The DSK 516 is used especially in equipment with diameters down to 17 mm minimum, also with flush-mounted G ½” membranes. The DSK 519 is designed for low pressure applications such as hydrostatic fill level measurements; it is mechanically robust and will handle overloads. |
| IN MONOLITHIC DESIGN Type DSK 611 (Ø = 18 mm) |
2 bar up to 400 bar | in OEM equipment demanding attractive price-performance ratios |
| PIEZORESISTIVE STAINLESS STEEL SENSOR | NOMINAL PRESSURES | APPLICATIONS |
|---|---|---|
| WITHOUT FILLING MEDIA with thinfilm technology with microfused technology |
2,5 bar up to 1,200 bar 3,5 bar up to 700 bar |
in OEM and industrial devices, especially hydraulic applications and technical gases demanding welded sensors without oil filling |
| FOIL STRAIN GAUGE | NOMINAL PRESSURES | APPLICATIONS |
|---|---|---|
| FOR HIGH AND HIGHEST PRESSURES | 1.000 bar up to 6.000 bar | in industrial devices with high static pressures that also demand high stability under dynamic compressive loads as found in water jet cutting equipment and hydraulic test rigs |
| CAPACITIVE CERAMIC PRESSURE SENSOR MODULES |
NOMINAL PRESSURES | APPLICATIONS |
|---|---|---|
| Type DSK 705 M (Ø = 32,4 mm) Type DSK 720 M (Ø = 19 mm) |
60 mbar up to 20 bar 100 mbar up to 50 bar |
in industrial devices and precision instruments, especially hydrostatic level measurement and applications demanding high performance yet mechanical robustness and overload capability, also high resistance against aggressive media |
