SSI SERIES AMPLIFIED
STAINLESS STEEL
PRESSURE SENSORS
The SSI pressure sensors perform precision digital signal conditioning
and provide analogue and digital output at the same time. The sensors
are calibrated, temperature compensated and linearized and achieve
very high total accuracies. The stainless steel construction allows for
high media compatibility with corrosive liquids and gases. Available
packaging options include diaphragm versions with weld ring or
housings with G 1/8 and 1/4 NPT threaded pressure ports. All SSI
pressure sensors can be modified according to customer specific
requirements.

Specification notes (cont.)
(3) Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis, and temperature
effects. Linearity is the measured deviation based on a straight line. Hysteresis is the maximum output difference at any
point within the operating pressure range for increasing and decreasing pressure. Calibration errors include the
deviation of offset and full scale from nominal values.
(4) Max. delay time between pressure change at the pressure die and signal change at the output.
(5) The response time depends on the adjusted internal A/D resolution of the sensor. For 13 bit it is typ. 2 ms. Other A/D
resolutions and response time are available on request. Please contact TE Connectivity for further information.
(6) Sensors with lower current consumption are available on request. Please contact TE Connectivity for further information.
(7) Full Scale Span (FSS) is the algebraic difference between the output signal for the highest and lowest specified pressure.
