sx smt series microstructure pressure sensors 0 psi to 1 psi through 0 psi to 150 psi the sx smt series provides a most cost-effective method of measuring absolute and gage pressures in a fully packaged sensor. these sensors are designed primarily for use with clean, dry gases such as air and nitrogen. this series features the standard sx chip in a ceramic, surface mount package. the standard version features a low profile plastic lid to better withstand high temperatures. the optional ported device offers a tube attachment port that is particularly useful in gage applications. the 4-pin closed bridge configuration allows electrical connection with additional pads provided for mechanical support. pulsed power is recommended to achieve maximum accuracy and conserve battery power in portable applications. features ? low cost ? small size ? absolute or gage pressures ? high-impedance bridge ? low power consumption potential applications ? pneumatic controls ? automotive diagnostics ? medical equipment/ instrumentation ? dental equipment ? environmental controls ? barometric pressure measurement ? altimeters ? pneumatic controls ? battery powered equipment
