DESCRIPTION
The 86BSD is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L
stainless steel housing. This 14-bit digital output pressure sensor supports I
2
C and SPI interface protocols, may
come in a 3.3 or 5.0Vdc supply voltage and is designed for o-ring mounting. The sensing package utilizes
silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element.
The 86BSD is designed for high performance, low pressure applications. A custom ASIC is used for
temperature compensation, offset correction, and provides a digital output of 10~90% or 5~95%.
For a similar sensor with stainless steel fittings, refer to the 85BSD digital output pressure sensor.

Notes
1.
Measured at vacuum for absolute(A), ambient for gage(G) and sealed gage(S). Output is not ratiometric to supply voltage.
2.
Accuracy: combined linearity, hysteresis and repeatability.
3.
Total Error Band: includes calibration errors and temperature effects over the compensated range. See Figure 3.
4. The deviation from a best fit straight line (BFSL) fitted to the output measured over the compensated temperature range. For errors
beyond the compensated temperature range, See Figure 2.
5.
Between case and sensing element.
6. 2X or 400psi, whichever is less. The maximum pressure that can be applied to a transducer without changing the transducer’s
performance or accuracy.
7. 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.
8. Maximum temperature range for product with standard cable and connector is -20°C to +105°C.
9. Start time to data ready is the time to get valid data after POR (Power on Reset). The time to get subsequent valid data is t hen
specified by the response time specification.
