Piezoresistive OEM Pressure Transducer Series 100 pages

Piezoresistive OEM Pressure Transducers
Series 10
sealed gauge, absolute, vented gauge, differential
The Series 10 pressure transducers cover all pressure ranges from 100 mbar to 1000 bar. They
have been produced for over 30 years and are the premium product of the KELLER OEM-line.
They are delivered with engraved serial number and electrical leadouts. Several millions of these
pressure transducers are in use world-wide in a variety of different applications. Main fields of
application are: Level technology, pneumatics, hydraulics, avionics.
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 so as to ensure the transfer of the pressure from
the diaphragm to the sensing component.
Serie 10
All metal parts in contact with the pressure media are made of stainless steel 316 L. The fully
welded housing is vacuum-tight.
A Rugged Pressure Transducer
The piezoresistive chip immersed in silicone oil is welded into a housing made of stainless steel
316 L.
High Sensitivity
A nominal signal of 200 mV is obtained at a supply current of 1 mA for the standard pressure
ranges above 2 bar.
Serie 10 HD
Flexibility
Versions: absolute pressure, sealed gauge, barometric, vented gauge and wet/wet differential.
18 nominal measurement ranges from 0,1 to 1000 bar. Different materials (Hastelloy, Platinum,
Inconel, Monel among others). Various kinds of oil filling (olive oil, fluorinated oil, low temperature oil etc.)
Quality
Each pressure transducer is subjected to comprehensive tests as to its pressure response and
temperature characteristic, and is delivered with an individual calibration certificate stating the
characteristics as well as the results of all tests which were performed. Special testing is avai­able
l
if demanded by the customer.
The Series 10 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.
