MS4425
PC Board Mountable Pressure Sensor
0-100 mV Output
Voltage Excitation
Differential, Gage, and Absolute
Temperature Compensated
DESCRIPTION
The MS4425 is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-
in- line configuration and intended for cost sensitive applications where excellent performance and long-term
stability are required.
Integral temperature compensation is provided over a range of 0-50°C using laser-trimmed resistors.
The pressure sensor is available in absolute, gage or differential pressure ranges from 0-1 to 0-300 psi. The
pressure ports are 1/8” barbed ports which mate with 3/32” ID tubing. These tubes are parallel to the printed
circuit board to allow other boards to be located above the sensor. For a vertical mounted tube in gage or
absolute pressure, refer to the MS4426.

Notes
1. Ratiometric to supply voltage.
2. Best fit straight line. Non linearity for 5 psi Differential devices is 0.75%.
3. Maximum temperature error between 0°C and 50°C with respect to 25°C. For errors beyond the compensated temperature, see
Temperature Error Multiplier Chart below.
4. Long term stability over a one year period with constant voltage and temperature.
5. 3X or 400 psi max, whichever is less.
6. For more details refer to 4425/4426 Mounting Application Note.
