DESCRIPTION
The 89 compensated is a small profile, media compatible, piezoresistive silicon pressure sensor
packaged in a 316L stainless steel housing. The 89 compensated features 5/16-32 UNEF threads and can be
welded in place. It can also be packaged in a variety of threaded fittings such as 1/4 and 1/8NPT, 1/4BSP as
well as custom process fittings. Contact factory for threaded fitting options.
The 89 compensated is designed for high pressure 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 compensated 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 89 uncompensated and constant voltage datasheets for more information on
different features of the 89.

Notes
1. Calculated at FSP, 3000psi and 5000psi parts are tested at 2500psi.
2. Best fit straight line between 0 and FSP.
3. Over the compensated temperature range with respect to +25°C.
4. Load resistance to reduce measurement errors due to output loading.
5. Between case and sensing element.
6. 3X or 20,000psi, whichever is less.
7. 4X or 30,000psi, whichever is less. The maximum pressure that can be applied to a transducer without rupture of either the sensing
element or transducer.
8. Maximum temperature range for this product with standard cable and connector is -20°C to +105°C.
