NetScanner™ Model 9116 Ethernet Intelligent Pressure ScannerThe Model 9116 Pneumatic Intelligent Pressure Scanner is a completely self-contained high performance pressure acquisition module for multiple measurements of dry, non-corrosive gases. The scanner integrates 16 silicon piezoresistive pressure sensors of any pressure range with the latest microprocessor technology in a compact, rugged package. |

Each field-replaceable pressure sensor incorporates a temperature sensor and EEPROM for storage of calibration data as well as 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 zero, span, linearity and thermal errors. It also performs digital temperature compensation of the sensors to reduce 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 calibration upon request. This capability virtually eliminates sensor zero drift error and provides guaranteed system accuracy of up to ±0.05% FS (Full Scale) after rezero. This enhanced pressure scanner provides User Accessible Memory (UAM) to facilitate Test Configuration Management (TCM) through functionality derived from the IEEE-1451 standard for smart transducers. This enables test parameters to be entered and stored within the scanner for access by the host controller during test setup and operation. The 9116 can sample using up to three concurrent scan lists at continuous rates up to 500 measurements per channel per second in engineering units. Pressure data in engineering units is output through an auto-negotiating 10 or 100 Mbit Ethernet interface supporting both TCP and UDP protocols. The scanner is supplied with comprehensive Visual Basic-based software called NUSS for PC compatible computers. Firmware upgrades are made available at no charge via PSI’s website and can be downloaded to the scanner over the Ethernet interface using NUSS. The Model 9116 Intelligent Pressure Scanner is one component of the NetScanner™ System. Multiple NetScanner components measuring a wide variety of parameters and sharing the same command set can be networked to form a distributed intelligent data acquisition system. Dated 0904
