Physical Dimensions
General Description
The Amplified with Voltage reference line of low pressure sensors is based upon a proprietary technology to
reduce all output offset or common mode errors. This model provides a very stable 4-volt output with superior
output offset characteristics. Output offset errors due to change in temperature, stability to warm-up, stability to
long time period, and position sensitivity are all significantly reduced when compared to conventional compensa-
tion methods. In addition the sensor utilizes a silicon, micromachined, stress concentration enhanced structure to
provide a very linear output to measured pressure.
These calibrated and temperature compensated sensors give an accurate and stable output over a wide
temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry
gases and the like.
The output of the device is 0.25 to 4.25 volts. The device operates from any dc. supply voltage of 5.5 to 16 volts.
