154N Compensated 316L SS Pressure Sensor 19mm Diameter Package 0 - 100mV Output Absolute and Gage Temperature Compensated DESCRIPTION The 154N compensated is a 19 mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The 154N compensated 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 and constant voltage datasheets for more information on different features of the 154N.

For amplified output circuits, 3.012V 1% interchangeability with gain set resistor. See application schematic. 2. Measured at vacuum for absolute (A), ambient for gage (G). 3. Best fit straight line. 4. Over the compensated temperature range with respect to 25C. 5. Guarantees output/input ratiometricity. 6. Load resistance to reduce measurement errors due to output loading. 7. Between case and sensing element. 8. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer. 9. Maximum temperature range for product with standard cable and connector is -20C to +105C. 154N Compensated www.meas-spec.com 2/4 March 2011 154N Compensated DIMENSIONS CONNECTIONS 154N Compensated www.meas-spec.com 3/4 March 2011 154N Compensated APPLICATION SCHEMATIC ORDERING INFORMATION 154N - 050 G - C T Vent (T = Tube, Blank = No Tube) Electrical (C = Ribbon Cable with Connector, R = Ribbon Cable, P = Solder Pads) Type (A = Absolute, G = Gage) Pressure Range Model NORTH AMERICA EUROPE Measurement Specialties 45738 Northport Loop West Fremont, CA 94538 Tel: 1-800-767-1888 Fax: 1-510-498-1578 Sales: pfg.cs.amer@meas-spec.com Measurement Specialties (Europe), Ltd. 26 Rue des Dames 78340 Les Clayes-sous-Bois, France Tel: +33 (0) 130 79 33 00 Fax: +33 (0) 134 81 03 59 Sales: pfg.cs.emea@meas-spec.com ASIA Measurement Specialties (China), Ltd.
