| Model 154N UltraStable Medical Instruments 316 SS Pressure Sensor 0-100 mV Output Gage, Sealed Gage and Absolute Temperature Compensated Process Control Waste Water Management Refrigeration/Compressors Pressure Transmitters Level Systems DESCRIPTION The Model 154N is a media compatible, compensated, piezoresistive silicon pressure sensor packaged in a 316 stainless steel housing. The sensing package utilizes silicone 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 FEATURES O-ring Mount 0.1% Pressure Non-linearity -20c To +85c Compensated Temperature Range 1.0% Interchangeable Span (Provided By Gain Set Resistor) Solid State Reliability Low Power available.

Best fit straight line. Over Temperature range: -20C to +85C Span with respect to +25C. 15 psi range sensors have a temperature error of 0.75% (Max) of Zero from -20C to 85C. Guarantees output/input ratiometricity. 7. 8. 9. Load resistance to reduce measurement errors due to output loading. Between case and sensing element. Maximum temperature range for product with standard cable and connector is -20C to +105C. 10. Weight depends upon configuration (cable, connector). 11. Standard gauge units are not recommended for vacuum applications. For vacuum applications, contact factory. 12. For pressure ranges < 15 psi, consult factory on performance specifications.
