Keller OEM Sensors, Transducers Series 9 OEM all media pressure sensor
The Series 9 pressure sensor is the most economic version for pressure ranges from 100 mbar to 200 bar. The standard version is supplied with connecting pins (leadouts are itted only on request) and the serial number is not engraved. 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 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: Measurement of altitude, aviation electronics, meteorology, servo controls,
robotics, hydraulics, sanitary and pharmaceutical engineering, underground mining, injection engineering! Rugged, Small Dimensions, Light Weight The piezoresistive chip immersed in silicone oil is welded into a housing made of stainless steel
316L. Diameter 19 mm; Height 5 mm; Weight 8 grammes. High Sensitivity A nominal signal of 200 mV is obtained at a supply current of 1 mA for standard pressure ranges above 2 bar.
Ranges from 0,1 to 200 bar
Absolute pressure, sealed gauge, differential, barometric, vented gauge and wet/wet differential. 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 demanded by the customer.
The Series 9 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 mproves the resistancy against crevice corrosion and still retains all the traditional performance, stability and quality for which KELLER is renowned.
