SDX Series Plastic Silicon Pressure Sensors Low Cost, Temperature Compensated, DIP, 0 psi to 1 psi, 0 psi to 100 psi DESCRIPTION The SDX devices feature an integrated circuit (IC) sensor The SDX Series sensors provide a very cost-effective solution element and laser trimmed thick film ceramic housed in a for pressure applications that require small size plus compact solvent resistant case. The package is a double-wide, performance. These calibrated and temperature-compensated dual-inline package (DIP). This is the same familiar package sensors give an accurate and stable output over a 0 C to 50 used by IC manufacturers except it is only 11,94 mm 0.470 in C 32 F to 122 F temperature range. This series is intended long and has a pressure port(s). The PC board area used by 2 for use with non-corrosive, non-ionic working fluids such as air each DIP is approximately 0.26 in . This extremely small size and dry gases. enables the use of multiple sensors in limited available space. The DIP provides excellent corrosion resistance and isolation Devices are available to measure absolute and gage pressures to external package stress. from 1 psi (SDX01) up to 100 psi (SDX100). The absolute devices have an internal vacuum reference and an output The DIP mounts on a PC board like a standard IC with voltage proportional to absolute pressure. The SDX devices through-hole pins. The pins anchor the pressure sensor to the are available in standard commercial and prime grades PC board and provide a more secure and stable unit than other (SDCXXXXX-A) to allow optimization of accuracy and cost in types of packages. any given application. The output of the bridge is ratiometric to the supply voltage and operation from any dc supply voltage up to 20 Vdc is acceptable.
