| Model 4425 * * * * * PC Board Mountable Pressure Sensor 0-100 mV Output Voltage Excitation Differential and Absolute Temperature Compensated DESCRIPTION The 4425 is a temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-inline 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 0-50C using laser-trimmed resistors. The pressure sensor is available in absolute 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 model 4426. For pressures below 1 psi, refer to the model 4415/4416.
