154BC Low Cost 316L Stainless Steel or Titanium 19mm Diameter Package 0 - 100mV Output Gage and Absolute Wide Compensated Temperature Range DESCRIPTION The 154BC is a 19mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel or ASTM Grade 2 CP titanium housing. The 154BC is a low cost unit designed without a header for o-ring mounting and OEM applications where compatibility with corrosive media is required. The titanium option offers greater resistance to corrosive materials and harsh cleaning chemicals, opening the range of its application use to things such as dialysis machines and salt/brackish water measurements. The sensing package utilizes silicone oil to transfer pressure from either a 316L stainless steel or titanium 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 154.

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 25°C. 5. Guarantees output/input ratiometricity. 6. Load resistance to reduce measurement errors due to output loading. 7. Between case and sensing element. 8. 2X or 500psi, whichever is less. The maximum pressure that can be applied without changing the transducer’s performance or accuracy. 9. 3X or 600psi, whichever is less. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer. 10. Maximum temperature range for product with standard cable and connector is -20°C to +105°C. 154BC www.meas-spec.com 2/4 February 2015 154BC DIMENSIONS 154BC www.meas-spec.com 3/4 February 2015 154BC APPLICATION SCHEMATIC ORDERING INFORMATION 154BC - S - 100PG - C Model - Material - Pressure Type and Range - Electrical 154BC - - P = Solder Pads R = Ribbon Cable C = Cable w/ Connector S = 316L Stainless Steel T = ASTM Grade 2 CP Ti - 015PG 030PG 050PG 100PG 300PG 007BA 012BA 018BA 028BA NORTH AMERICA EUROPE Measurement Specialties 45738 Northport Loop West Fremont, CA 94538 Tel: 1-800-767-1888 Fax: 1-510-498-1578 Sales: [email protected] 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: [email protected] ASIA Measurement Specialties (China), Ltd.
