SS109 piezoresistive OEM pressure transducer
2013-06-19

Piezoresistive OEM Pressure transducers absolute- and gauge Pressure

The SS109 series pressure transducers are extremely durable, even when exposed to fast pressure peaks. They have been developed especially for the measurement of high pressures. The SS109 series sensor for ranges 2­-1000 bar uses a thicker glass feed through and a wire-bonded measuring cell.

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 filed with silicone oil for the transfer of the pressure from the diaphragm to the sensing component.

All metal parts in contact with the pressure media are made of stainless steel AISI 316 L. The fully welded housing is vacuum-tight. The connecting pins allow direct PCB mounting or can be used for connecting cables.

Typical applications: Industrial processes, aviation electronics, servo controls,oil industry, robotics

A Rugged Pressure Transducer
The piezoresistive chip immersed in silicone oil is welded into a housing made of stainless steel AISI 316 L.

High Sensitivity
A nominal signal of 100 mV is obtained at a supply current of 1.5 mA for all standard pressure Ranges.
