SDX010IND4

Microstructure Pressure Sensors Compensated 0 in H2O to 5 H2O in H2O SDX IND Series and 0 in H2O to 10 in H2O FEATURES Low Cost Dual Inline Package Temperature Compensated Calibrated Zero and Span Small Size Low Noise High Impendance for Low Power Applications TYPICAL APPLICATIONS Medical Equipment Computer Peripherals The SDX series sensors provide a very cost effective solution for pressure Pneumatic Controls applications that require small size plus performance. These calibrated and HVAC 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 H O to 10.0 in H O full scale range. The output of the 2 2 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 mm 0.26 in . 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.

Span is ratiometric to the supply voltage. Note 2: Reference conditions (unless otherwise noted): Supply voltage, V = 12 Vdc, TA = 25 C 77 F , Common Mode Line Pressure = S 0 psig, pressure applied to port 2 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 F reading. Note 5: Maximum difference in output at any pressure with the operating pressure range and temperature within 0 C to 50 C 32 F to 122 F after: a) 100 temperature cycles, C to 50 C 32 F to 122 F b) 1.0 million pressure cycles, 0 in H O to full-scale span 2 Note 6: Input impedance is the impedance between V and ground S 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. Honeywell Sensing and Control 2
