Integrated Pressure Transducer (IPT)

ETLG Inertial Aerosystems:The Integrated Pressure Transducer (IPT) provides high accuracy pressure data in an industry standard SPI digital format. Manufactured by Honeywell Aerospace, the core of the IPT is a proven Honeywell silicon piezoresistive pressure sensor with both pressure and temperature sensitive elements.

The IPT is small and lightweight and can be easily integrated by the user into a wide variety of applications that require high performance in a small package. Applying the coefficients stored in the on-board EEPROM to the normalized IPT pressure and temperature output yields highly accurate and stable pressure readings over the -40 to 85°C compensated temperature range.

The IPT has high accuracy of ±0.04% FS Total Error Band (absolute pressure), to ±0.10% FS Total Error Band (gauge/ differential pressure)  over a wide temperature (-40 to 85°C). No additional pressure and temperature calibration is necessary.

An industry standard interface ( Digital SPI Output) provides ready communication between a µController/µProcessor and the IPT.

Small and Versatile-Volume (16 cmᶟ ). Lightweight – less than 10 grams. Media Interface – Handles most dry gas media.

APPLICATIONS: Air Data Computers, Altimeters , Cabin Air Pressure , Engine Test Cells , Flight Test Systems , Meteorology , Flow and Pressure Calibrators  Instrumentation and Analytical Equipment , Research and Development.
