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. FEATURES AND BENEFITS  High Accuracy Over a Wide Temperature Range From -40 to 85 C 0.04% FS Total Error Band (absolute pressure), to 0.10% FS Total Error Band (gauge/ differential pressure) (1)  Stored Correction Coefficients in EEPROM – Ready to use; No additional pressure and temperature calibration necessary. Simplifies System Design – No additional signal compensation needed to achieve a highly accurate pressure reading.  Digital SPI Output  Industry Standard Interface – Ready communication between a µController/µProcessor and the IPT.  Small and Versatile  Volume ~ 1 in3 (16 cm3) Lightweight – Less than 10 grams. Media Interface – Handles most dry gas media. APPLICATIONS:  Air Data Computers  Altimeters  Cabin Air Pressure  Engine Test Systems  Flight Test Systems  Meteorology  Flow and Pressure Calibrators  Instrumentation and Analytical Equipment  Research and Development Excellent Pressure Stability 0.04% FS Total Error Band, -40 to 85ºC, Absolute ISO-9001 ISO-14001 Small and Lightweight ±0.10% FS Total Error Band, -40 to 85ºC, Gauge/ Differential

(1) Total Error is the sum of worst case linearity, repeatability, hysteresis, thermal effects, and calibration errors over the operating temperature range. Accuracy is only achieved after applying the correction coefficients and algorithm as shown in section 3.2. of Product Specification (FS = Full Scale) . F or total error calculations of differential units, “Full Scale” is the pressure difference between the minimum and maximum pressures. For example, full scale for a 1 psid PPT is 2 psi ( -1 to +1 psi). Pressure range 1psi gauge has total error of ±0.20% FS. (2) After applying the c orrection coefficients stored in EEPROM, the resultant pressure reading is expressed in PSI (pounds per square inch). (3) Not including mounting hardware.
