¢ Low Cost DIP General Description e« Temperature Compensated The SDX series sensors will « Calibrated Zero and provide a very cost effective Span solution for pressure applica- e¢ Small Size tions that require small size e Low Noise plus performance. These calib- e High Impedance for rated and temperature compen- Low Power sated sensors give an accurate Applications and stable output over a 0°C to 50°C temperature range. This icati series is intended for use with non-corrosive, non-ionic working Se rredcal Ecuipment fluids such as air, dry gases and the like. * Computer Peripherals The SDXLOO5D4 devices are specifically designed to measure « Pneumatic Controis low pressures. They feature a 0 to 5 IN H20 full scale pressure « HVAC range. . . . The output of the bridge is ratiometric to the supply voltage and Equivalent Circuit operation from any D.C. supply voltage up to +20 Vis acceptable. “ The SDX 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., 0.600” lead spacing) dual-inline-package. This is the same familiar package used by IC manufacturers except it has integral pressure port(s). The pc board area used by each DIP is approximately 0.26 square inches. This extremely small size = Out enables the use of multiple sensors in limited available space. 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 “ss and provide a more secure and stable unit than other types of i packages. me

Note 2: Span is the algebraic difference between the output voltage at full scale pressure and the output at zero pressure. Span is tatiometric to the supply voltage. Note 3: Hysteresis is the maximum output difference at any point within the operating pressure range for 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 reading. Note 5: Maximum difference in output at any pressure with the operating pressure range and temperature within 0°C to +50°C after. a) 100 temperature cycles, 0°C to +50°C. b) 1.0 million pressure cycles, 0 psi to full scale span. Note 6: Input impedance is the impedance between Vs and ground. Note 7: Output impedance is the impedance between the + and - outputs. Note 8: This is the common mode voltage of the output arms for Vs=12 Vdc. Note 9: Response time for a 0 psi to full scale span pressure step change, 10% to 90% rise time. Note 10:Long term stability over a one year period. Rev82396 er ee a
