The 154N vacuum gage is designed for o-ring mounting and OEM applications where compatibility with corrosive media is required. The sensing  package  utilizes  silicone  oil  to  transfer pressure from the 316L stainless steel diaphragm to the sensing element.  A ceramic substrate is attached to the package that contains laser-trimmed resistors for temperature compensation and offset correction. An additional laser-trimmed  resistor is included which can be used to adjust an external differential amplifier and provide span interchangeability to within ±1%. Please refer to the 154N uncompensated, compensated and constant voltage datasheets for more information on different features of the 154N.
