IPT0001D33R

INTEGRATED PRESSURE TRANSDUCER 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 • ±0.04% FS Total Error Band (absolute pressure units) ±0.10% FS Total Error Band (gauge/differential pressure) from -40 to +85°C.

Accuracy is only achieved after applying the correction coefficients and algorithm as shown in section 3.2. of User’s Manual (FS = Full Scale). For 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 IPT is 2 psi (-1 to +1 psi). Pressure range 1psi gauge has total error of ±0.20% FS. (2) After applying the correction coefficients stored in EEPROM, the resultant pressure reading is expressed in PSI (pounds per square inch). (3) Not including mounting hardware.
