The SDX series sensors provide a very cost effective solution for pressure
applications that require small size plus performance. These calibrated and
temperature compensated sensors give an accurate and stable output over
a 0
°
C to 50
°
C [32
°
F to 122
°
F] range. This series is intended for use with
non-corrosive, non-ionic working fluids, such as, air and other dry gases.
The SDX series devices are specifically designed to measure low
pressures with a 0 in H2O to 10.0 in H2O full scale range. The output of the
bridge is ratiometric to the supply voltage up to 20.0 Vdc is acceptable.
The SDX series devices feature an integrated circuit sensor element and
laser trimmed thick film ceramic housed in a compact solvent resistant case.
The package is a double wide (i.e. 15,24 mm [0.600 in] lead spacing) dual
inline package. This is the same familiar package used by IC manufactures
except it has integral pressure port(s). The PC board area used by each DIP
is approximately 6,60 mm² [0.26 in²]. This extremely small size enables the
use of multiple sensors in limited available space. The DIP provides
excellent isolation to external package stress.
The DIP mounts on a PC board like a standard IC with through-hole pins.
The pins anchor the pressure sensor to the PC board which provides a more
secure and stable unit than other types of packages.

SPECIFICATION NOTES
Note 1: Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure. Span is
ratiometric to the supply voltage.

Note 3: Hysteresis is the maximum output difference at any point within the operating pressure range fro increasing and decreasing
pressure.
Note 4: Maximum error band of the offset voltage and the error band of the span, relative to the 25
°
C [77

Note 6: Input impedance is the impedance between VS and ground
Note 7: Output impedance is the impedance between the + and – outputs.
