Keller OEM Sensors, Transducers Series 8 OEM all media pressure sensor

The Series 8 pressure sensors are extremely durable, even when exposed to fast pressure peaks. They have been developed especially for the measurement of high pressures. The Series 8 sensor for ranges 400!-1000 bar uses  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 inluences by a stainless steel housing sealed with a concentrically corrugated diaphragm. The housing is illed 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 200 mV is obtained at a supply current of 1 mA for all standard pressure ranges.
Flexibility Versions: Absolute and sealed gauge pressure. 9 nominal measurement ranges from 10 to 1000 bar. Different materials and oil illings (see options verso).Quality
Each pressure transducer is subjected to comprehensive tests for its pressure response and temperature characteristics, and is delivered with an individual calibration certiicate stating the characteristics as well as the results of all tests which were performed. Special testing is available if demanded by the customer.
The Series 8 can also be delivered with a laser welded media isolation diaphragm (see data sheet Series 3 L - 10 L). The new technique for laser welding stainless steel diaphragms further improves the resistancy against crevice corrosion and still retains all the traditional performance, stability and quality for which KELLER is renowned.
