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.  APPLICATIONS 316L SS Pressure Sensor 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). Best fit straight line. Values for 5PSIG devices are as follows: Non-linearity: ±0.2% max Temp coefficient (offset): -80 min, 80 max Long term stability (offset): ±0.25 TYP Pressure hysteresis:-0.1min,0.1max. Bridge resistance is measured with both –E pins shorted together. TC values are first order coefficients to a quadratic fit over a temperature range of -20 to +85°C (0 to +50°C for 5psi). Between case and sending element. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer. The maximum pressure that can be applied without changing the transducer’s performance or accuracy Standard gage units are not recommended for vacuum applications. 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. Marking: Part marked with Model Number, Pressure Range, Type, Lot Number, Serial Number and Date Code. 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.
