DESCRIPTION
The 154BC is a 19mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a
316L stainless steel or ASTM Grade 2 CP titanium housing. The 154BC is a low cost unit designed without a
header for o-ring mounting and OEM applications where compatibility with corrosive media is required. The
titanium option offers greater resistance to corrosive materials and harsh cleaning chemicals, opening the range
of its application use to things such as dialysis machines and salt/brackish water measurements.
The sensing package utilizes silicone oil to transfer pressure from either a 316L stainless steel or titanium
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 154N uncompensated and constant voltage datasheets for more information on different
features of the 154.

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. Guarantees output/input ratiometricity.
6. Load resistance to reduce measurement errors due to output loading.
7. Between case and sensing element.
8. 2X or 500psi, whichever is less. The maximum pressure that can be applied without changing the transducer’s performance or accuracy.
9. 3X or 600psi, whichever is less. 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°C to +105°C.
