NetScanner 9916 Pressure Scanner

Each field-replaceable pressure sensor incorporates a temperature sensor and an integral EEPROM for storage of personalized calibration data as well as sensor information such as serial number, pressure range, factory calibration date. Integrating the EEPROM within the sensor enables simplified field replacement of sensors with automatic uploading of sensor data during power up. 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). The Model 9916 can sample using up to three concurrent scan lists a continuous rates up to 100 measurements per channel per second in engineering units with timestamps. Pressure data in engineering units is output through an auto-negotiating 10 or 100 Mbit Ethernet interface supporting both TCP and UDP protocols. The Model 9916 data output optionally includes data time stamps derived from either the 9916 internal real time clock, NTP clock or an IEEE 1588-2008 Precision Time Protocol (PTPv2) grand master clock.

The scanner is supplied with comprehensive software called NUSS for PC compatible computers. Firmware upgrades are available at no charge and can be downloaded to the scanner over the 9916 Ethernet interface using NUSS. The Model 9916 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.
