(SDXxxxyy-A)
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] temperature range. This series is intended
for use with non-corrosive, non-ionic working fluids such as air, dry gases
and the like.
TYPICAL APPLICATIONS
• Medical Equipment
• Computer Peripherals
• Pneumatic Controls
• HVAC
Devices are available to measure absolute and gage pressures from 1 psi
(SDX01) up to 100 psi (SDX100). The absolute devices have an internal
vacuum reference and an output voltage proportional to absolute pressure.
The SDX devices are available in standard commercial and prime grades
(SDCxxxyy – A) to allow optimization of accuracy and cost in any given
application.
The SDX devices feature an integrated circuit (IC) sensor element and laser
trimmed thick film ceramic housed in a compact solvent resistant case. The
package is a double-wide (i.e. 0.600 inches lead spacing) dual-inline
package (DIP). This is the same familiar package used by IC manufacturers
except it is only 11,94 mm [0.470 in] long and has a pressure port(s). The pc
board area used by each DIP is approximately 0.26 in2. This extremely small
size enables the use of multiple sensors in limited available space. The DIP
provides excellent corrosion resistance and 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 and provide a more
secure and stable unit than other types of packages.
The output of the bridge is ratiometric to the supply voltage and operation
from any dc supply voltage up to 20 Vdc is acceptable.
