The KPZ21 G is designed for measurement oi relative pressures up to 10 bar and for a wide range of gases or fluids. The sensor employs thin-film semiconductor strain gauges deposited on a beryllium copper isolating diaphragm. Sealing is obtained by pressure contact using an 0-ring in a groove provided in the transfer-moulded body and electrical connections are made via silverplated leads-outs to form a dual-in-line configuration. All pressure media, which do not attack CuBe, epoxy novolack piastre, epoxy glue and assembly parts may be used.
