DESCRIPTION
The Model 154N
The Model 154N is a media
compatible, compensated, piezoresistive silicon
pressure sensor packaged in a 316 stainless steel
housing. The sensing package utilizes silicon oil to
transfer pressure from the 316 stainless steel
diaphragm to the sensing element.
The Model 154N is designed for low pressure
applications. A ceramic substrate is attached to the
package that contains laser-trimmed resistors for

1. For amplified output circuits, 3.012V ± 1% interchangeability with
gainset resistor. See Application Note TN-003.
2. Measured at vacuum for absolute (A), ambient for gage (G).
3. Best fit straight line.
4. Over Temperature range: -20°C to +85°C Span with respect to +25°C.
5. 15 psi range sensors have a temperature error of ±0.75% (Max) of Zero
from -20°C to 85°C.
6. Guarantees output/input ratiometricity.
7. Load resistance to reduce measurement errors due to output loading.
8. Between case and sensing element.
9. Maximum temperature range for product with standard cable and
connector is –20°C to +105°C.
10. Weight depends upon configuration (cable, connector).
11. Standard gauge units are not recommended for vacuum applications.
For vacuum applications below 1/2 atmosphere, contact factory.
12. For pressure ranges < 15 psi, consult factory on performance
specifications.
