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.

Notes
1. Measured at vacuum for absolute (A), ambient for gage (G).
2. Best fit straight line.
3. Over the compensated temperature range with respect to 25°C.
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 +105°C.
