85 Uncompensated 316L SS Pressure Sensor Small Profile 0 - 100mV Output Absolute and Gage DESCRIPTION The 85 vacuum uncompensated pressure sensor is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. The 85 vacuum uncompensated pressure sensor 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 other custom process fittings. The 85 uncompensated 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. Please refer to the 85 compensated and constant voltage datasheets for more information on different features of the 85.

Measured at vacuum for absolute (A) and at ambient for gage (G). 2. Best fit straight line. Non linearity is 0.2% max for 5psiG devices. 3. Pressure hysteresis is min -0.1 to max 0.1 for 5psi absolute. 4. Bridge resistance is measured with both -E pins shorted together. 5. TC values are first order coefficients to a quadratic fit over a temperature range of -20 to +85C (0 to +50C for 5psi). 6. 5psiA is -1.7K ~ -1.0K ppm/C. 7. Between case and sending element. 8. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer. 85U www.meas-spec.com 2/4 June 2014 85 Uncompensated DIMENSIONS CONNECTIONS 85U www.meas-spec.com 3/4 June 2014 85 Uncompensated ORDERING INFORMATION 85 - 005 G - 0 U T Vent (T = Tube, Blank = No Tube) Electrical (U = Open Bridge, Uncompensated) 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.
