Piezoresistive OEM Pressure Transducers Series 7

The Series 7 pressure sensors are for medium pressure ranges, and are the smallest, lightest isolated OEM-sensors available. They have a diameter of only 15 mm without compromising quality and performance.

A high-sensitivity piezoresistive silicon chip is used for pressure sensing. The chip is protected against ambient influences by a stainless steel housing sealed with a concentrically corrugated diaphragm. The housing is filled with silicone oil for the transfer of the pressure from the diaphragm to the sensing component.


They should be preferred over Series 9 where smallest dimensions and low weight bring advantages.

The LC version has embedded signal conditioning providing a 0.5-4.5 v output ( requires a regulated 5v supply).

 

Specifications
Excitation Constant Current 0,5 to 5 mA;
Specifications apply for 4 mA
LC models require 5v regulated supply
Pressure Ranges 5...200 bar (abs.)
Dimensions ø 15 x 5 mm
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: 5...200 bar: nominal 600 mV FS. LC models 0.5-4.5v O/P
Note: For best linearity, the full scale signal should be kept low. At 100mV FS, linearity of 0,1% is realisable. For highest performance with digital compensation, signals of 500...700mV FS give best results. Silicon sensors start to fail at 600mV, most at 750mV, with extremes at 1000mV at 1mA excitation.
