85 Constant Voltage 316L SS Pressure Sensor Small Profile 0 - 100mV Output Absolute and Gage Temperature Compensated DESCRIPTION The 85 constant voltage is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The 85 constant voltage is offered in a weldable package or with a variety of threaded fittings such as 1/4 and 1/8NPT, 1/4BSP as well as custom process fittings. The 85 constant voltage is designed for OEM applications where compatibility with corrosive media is required. The sensing package utilizes silicon 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. Please refer to the 85 uncompensated and compensated datasheets for more information on different features of the 85.

Measured at vacuum for absolute (A), ambient for gage (G). 2. Best fit straight line. 3. Over the compensated temperature range with respect to 25C. 4. Guarantees output/input ratiometricity. 5. Load resistance to reduce measurement errors due to output loading. 6. Between case and sending element. 7. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer. 8. Maximum temperature range for product with standard cable and connector is -20 to +105C. 85CV www.meas-spec.com 2/4 September 2014 85 Constant Voltage DIMENSIONS APPLICATION SCHEMATIC 85CV www.meas-spec.com 3/4 September 2014 85 Constant Voltage ORDERING INFORMATION 85CV - 050 G - 0 C T Vent (T = Tube, Blank = No Tube) Electrical (R = Ribbon Cable, C = Cable with connector) Fitting Type (0 = Weldable, See Fittings) 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.
