IC Sensors MODEL 154N Ultrastable 316 SS Pressure Sensor 0-100 mV Output Gage, Sealed Gage and Absolute Temperature Compensated DESCRIPTION The Model 154N The Model 154N is a media compatible, compensated, piezoresistive silicon pressure sensor packaged in a 316 stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316 stainless steel diaphragm to the sensing element. The Model 154N is designed for low pressure applications. 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 sensitivity variations by setting the gain of an external differential amplifier to within 1% interchangeability. Alternatives include cap-ring Models 84 or 86, 1/4 NPT Model 96, and Model 85. High pressure sensors are also available.
