The 9216 series NetScanner pneumatic px scanner w ptp integrates 16 silicon piezoresistive pressure sensors of any pressure range with the latest microprocessor technology in a compact, ruggedized package.  Each field replaceable pressure sensor incorporates a temperature sensor and EEPROM for storage of calibration data along with sensor identification information such as pressure range, factory calibration date and user-managed last or next calibration date. The microprocessor uses the data from the EEPROM to correct for sensor offset, span, linearity and thermal errors. The microprocessor’s digital temperature compensation algorithm reduces sensor thermal errors by a factor of ten or more over conventional sensor compensation. The microprocessor also controls the actuation of an integral manifold to execute on-line zero or span calibrations upon request. This capability virtually eliminates sensor offset drift error and provides system accuracy errors less than ±0.05% FS (Full Scale).
