Temperature Compensated
The 85 compensated is a small profile, media
compatible, piezoresistive silicon pressure sensor packaged in a
316L stainless steel housing. The 85 compensated 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 compensated 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. An
additional laser trimmed resistor is included which can be used to
adjust an external differential amplifier and provide span
interchangeability to within ±1%.
Please refer to the 85 uncompensated and constant
voltage datasheets for more information on different features of
the 85

Notes
1. For amplified output circuits, 3.012V ±1% interchangeability with gain set resistor. See application schematic.
2. Measured at vacuum for absolute (A), ambient for gage (G).
3. Best fit straight line.
4. Over the compensated temperature range with respect to 25°C.
5. 15psi range sensors have a temperature error
–
offset of ±0.75% (max).
6. Guarantees output/input ratiometricity.
7. Load resistance to reduce measurement errors due to output loading.
8. Between case and sending element.
9. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer.
10. Maximum temperature range for product with standard cable and connector is -20 to +105°C.
