SDX15A4-A

Product Description

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 temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. Devices are available to measure absolute and gauge pressures from 1 psi up to 100 psi. The absolute devices have an internal vacuum reference and an output voltage proportional to absolute pressure. The output of the bridge is ratiometric to the supply voltage and operation from any DC supply voltage up to +20 V is 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-inlinepackage. This is the same familiar package used by IC manufacturers except it is only 0.470" long and has a pressure port(s). The pc board area used by each DIP is approximately 0.26 square inches. 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.

SPECIFICATION NOTES

Note1: Reference Conditions (unless otherwise noted):

           TA = 25°C, Supply VS = 12 Vdc, Common Mode Line Pressure = 0 psig. Pressure applied to port 2. For absolute            devices only, pressure is applied to port 1 and the output polarity is reversed.

Note 2: Full-Scale Span is the algebraic difference between the output voltage at full-scale pressure and the output

           at zero pressure. Full-Scale Span (FSS) is ratiometric to the supply voltage.

Note 3: Pressure 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 resistance is the resistance between VS and ground.

Note 7: Output resistance is the resistance 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.
