The Model 9216 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, ruggedized package. Each fieldreplaceable 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 guaranteed system accuracy of up to ±0.05% FS (Full
Scale).

The 9216 can sample using up to three concurrent scan lists at continuous rates up to 500 measurements per channel per second in engineering units with timestamps. Pressure data in engineering units is output through an autonegotiating 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 our website and can be downloaded to the scanner over the Ethernet interface using NUSS.

The Model 9216 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.
