TE Connectivity (Berwyn, PA) has announced the 86BC, a 16-mm piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. O-ring mounting supports integration into industrial applications. The header-less unit utilizes silicon oil to transfer pressure from the steel diaphragm to the sensing element. A ceramic substrate is attached to the package containing laser-trimmed resistors, for temperature compensation and offset correction. An additional laser trimmed resistor adjusts an external differential amplifier and provides span interchangeability to within ±1%. Other features include 0-100mV output, -40 °C to +105 °C operating temperature, 1.0% interchangeable span, solid state reliability, and ±0.3% pressure non-linearity.
