The core of the IPT is a proven Honeywell silicon piezo-resistive pressure sensor with both pressure and temperature sensitive bridge elements. The IPT is both small and lightweight and can be easily applied to a wide variety of applications that require high performance in a small package. Applying coefficients stored in the on-board EEPROM to normalized IPT pressure and temperature digital output yields accurate and stable pressure readings over the -40ºC to +85ºC temperature range. The IPT piezo-resistive pressure sensing die contains two bridge circuits; one for pressure and one for temperature. The IPT provides an analog–to-digital converter for each of these data channels; 24-bit for pressure and 16-bit for temperature.
