• Absolute and Gage
• Temperature Compensated
DESCRIPTION
The 154N constant voltage is a 19 mm small profile, media compatible, piezoresistive silicon pressure
sensor packaged in a 316L stainless steel housing. The 154N constant voltage is designed for o-ring mounting
and OEM applications where compatibility with corrosive media is required.
The sensing package utilizes silicone 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 154N uncompensated and compensated datasheets for more information on
different features of the 154N.

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 sensing 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°C to +105°C.
