Piezoresistive silicon pressure sensor JC-CT02
●Product overview
JC-CT02 piezoresistive silicon pressure sensor compensated is a 19 mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The JC-CT02 compensated isdesigned 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%
