Keller OEM Sensors, Transducers Series 6S / SC OEM all media pressure sensor

These piezoresistive pressure transmitter-heads are produced on the new KELLER automatic brazing lines, making possible the mass production of high quality pressure transmitters at low cost. This new technology allows the crevice-free construction of the pressure port without using seals or O-rings. In the brass sensor line (Series 6 MC), a steel insert and a nickel dia-
phragm are brazed into a brass housing. In the steel version (Series 6 S, Series 6 SC), all parts are of stainless steel (AISI 316 L). The header with the silicon pressure sensor and the glass feed-through pins are welded to the steel insert underneath the oil filling. These transducers are the ideal basis for pressure transmitters, pressure switches or digital pressure instruments. The transducer heads come in 3 basic versions: 6MC: Compact version in brass, lowest price, accuracy 1 % FS.  Ranges 5!-200 ba Series 6 SC / 6 MC: Ranges 5!-200 ba 6SC: Compact version in stainless steel, accuracy 0,5 % FS.  Ranges: 5!-200 bar. (Compact Version) 6S: Stainless steel, highest performance, accuracy 0,5 % FS.  Ranges: 0,3!-1000 ba
