Product Specification

Amplified Pressure Sensors
-10 cm H2O to 120 cm H2O Pressure Sensor

Amplified Output Pressure Sensors General Description
This Amplified Output pressure sensor is based upon a proprietary technology to compensate all errors. This model provides a calibrated amplified output with superior output characteristics. Output characteristics are tested at pressure and temperature and then digitally compensated using a proprietary 3D mapping scheme. 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 ratiometric to the supply voltage over a supply voltage range of 4.5 to 5.5 volts.

Amplified Output Pressure Sensors Features
• 4 Volt ratiometric output
• Temperature Compensated
• Calibrated Zero and Span

Amplified Output Pressure Sensors Applications
• Medical Instrumentation
• Respiratory Breathing
