Keller UK’s Piezoresistive Pressure Transmitter-Heads

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 diaphragm 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.
