Keller Series 7S/9S miniature pressure transducer

Quick Overview

The Keller Series 7S / 9S is the latest development in media isolated piezoresistive silicon chip pressure transducers. The new low mass one-piece housing is smaller with a brazed stainless steel diaphragm for lower production cost, giving excellent long-term stability combined with easy installation.

Piezoresistive OEM Pressure Transducers Series 7S / 9S

The Series 7S / 9S is the latest development in media isolated piezoresistive silicon chip pressure transducers. The new low mass one-piece housing is smaller with a brazed stainless steel diaphragm for lower production cost, giving excellent long-term stability combined with easy installation.

The Series 7S / 9S can be installed into a housing using an O-ring seal, or it can be welded. Welding should only be made to the flange at the rear of the transducer. Performance specifications will remain unaffected by the installation or welding process. The O-ring seal may be fitted directly below the flange, or as a peripheral seal at the front face of the transducer. The rear flange can be modified or machined off completely where space is important.

 

 

Series 7 S: ø 19 mm

Series 9 S: ø 21 mm

Specification
Excitation Constant Current 0,5 to 5 mA;
Specifications apply for 4 mA
Pressure Ranges 0,2...200 bar (abs., gauge)
Dimensions Height 5,5 mm (diameter see above)
Linearity typ. < 0,5 % FS max. < 1,0 % FS
Comp. Temp. Range 0...50°C -10...80°C
T.C. of Zero < 0,1 mV / °C < 0,2 mV / °C
T.C. of Sensitivity < 0,01 % / °C < 0,03 % / °C
Long Term Stability typ. 2 mV 3 mV
Signal Ranges: 0,2...1 bar: 400 mV / bar
Ranges: 2...200 bar: nominal 600 mV FS
Note: For best linearity, the full scale signal should be kept low. At 100 mV FS, linearity of 0,1% is realisable. For highest performance with digital compensation, signals of 500...700 mV FS give best results. Silicon sensors start to fail at 600 mV, most at 750 mV, with extremes at 1000 mV at 1 mA excitation
