Integrated Pressure Transducer
IPT
Honeywell’s Integrated Pressure Transducer (IPT) provides high accuracy pressure data in an industry standard SPI
digital format. 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.
