85 Uncompensated SPECIFICATIONS 316L SS Pressure Sensor Small Profile 0 - 100mV Output Absolute and Gage FEATURES The 85 vacuum uncompensated pressure sensor is a small Weldable and Threaded Process Fittings profile, media compatible, piezoresistive silicon pressure sensor -40C to +125C Operating Temperature packaged in a 316L stainless steel housing. The 85 vacuum 0.1% Pressure Non Linearity uncompensated pressure sensor is offered in a weldable Solid State Reliability package or with a variety of threaded fittings such as 1/4 and 1/8NPT, 1/4BSP as well as other custom process fittings. APPLICATIONS The 85 uncompensated is designed for OEM applications where compatibility with corrosive media is required. The sensing Medical Instruments package utilizes silicon oil to transfer pressure from the 316L Process Control stainless steel diaphragm to the sensing element.

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. Values for 5PSIG devices are as follows: Non-linearity: 0.2% max Temp coefficient (span): -80 min, 80 max Long term stability (offset): 0.25 TYP 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. 9. Standard gage units are not recommended for vacuum applications. 10. Testing: 10.1 Units are not tested over temperature or pressure. 10.2 A final test is performed 1.5mA and room temperature for part functionality. 10.3 All units are subjected to 100% drift test. 11. Marking: Part marked with model number, pressure range, type (A for absolute, G for gage), lot number, serial number and date code. 12. Shipping and Packaging: The stainless steel diaphragm is protected by a static dissipative cap (No fitting options only). Each unit will be packaged individually in a plastic vial with anti-static foam. 13. Product description: Model 85-XXXX-XU(T) is a uncompensated micro machined piezoresistive silicon pressure sensor 14. Direct mechanical contact with diaphragm is prohibited. Diaphragm surface must remain free of defects (scratches, punctures, dents, fingerprints, etc.) for device to operate properly. Caution is advised when handling parts with exposed diaphragms. Use protective cap whenever devices are not in use. SENSOR SOLUTIONS ///85 07/2018 Page 2
