SDX01D4 - Honeywell Sensing and Control

SDX Series

Plastic Silicon Pressure Sensors

Low Cost, Temperature

Compensated, DIP, 0 psi to 1 psi,

0 psi to 100 psi

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 [32 °F to 122 °F] temperature range. This series is intended

for use with non-corrosive, non-ionic working fluids such as air

and dry gases.

Devices are available to measure absolute and gage pressures

from 1 psi (SDX01) up to 100 psi (SDX100). The absolute

devices have an internal vacuum reference and an output

voltage proportional to absolute pressure. The SDX devices

are available in standard commercial and prime grades

(SDCXXXXX-A) to allow optimization of accuracy and cost in

any given application.

The SDX devices feature an integrated circuit (IC) sensor

element and laser trimmed thick film ceramic housed in a

compact solvent resistant case. The package is a double-wide,

dual-inline package (DIP). This is the same familiar package

used by IC manufacturers except it is only 11,94 mm [0.470 in]

long and has a pressure port(s). The PC board area used by

each DIP is approximately 0.26 in2. 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.

The output of the bridge is ratiometric to the supply voltage and

operation from any dc supply voltage up to 20 Vdc is

acceptable.

Notes:

1. Full-Scale Span is the algebraic difference between the output voltage at full-scale pressure and the output at zero pressure.

Full-Scale Span is ratiometric to the supply voltage.

2. Maximum pressure above which causes permanent sensor failure.

3. Reference conditions:

• T

A = 25 °C (unless otherwise noted).

• Supply VS = 12 Vdc, Common Mode Line pressure = 0 psig.

• Pressure applied to Port B. For absolute devices only, pressure is applied to Port A and the output polarity is reversed.

4. Maximum zero pressure offset for absolute devices is ±500 mV.

5. Hysteresis is the maximum output difference at any point within the operating pressure range for increasing and decreasing

pressure.

6. Maximum error band of the offset voltage and the error band of the span, relative to the 25 °C [77 °F] reading.

7. Maximum difference in output at any pressure within the operating pressure range and the temperature within 0 °C to 50 °C

• 1.0 million pressure cycles, 0 psi to full-scale span.

8. Input resistance is the resistance between VS and ground.

9. Output resistance is the resistance between the + and - outputs.

10. Common Mode voltage of the output arms for VS=12 Vdc.

11. Response time for a 0 psi to Full-Scale Span pressure step change, 10% to 90% rise time.
