In addition, 5 VDC signals can be measured on any unused input channel. The 9022 also provides a precision +5 or +10 VDC excitation source to power external transducers. The scanner incorporates anti-aliasing filters for each channel with a choice of two frequency cutoffs; 30 and 250 Hz.
When used with 9400 transducers, the microprocessor corrects for pressure transducer zero, span, nonlinearity errors using data stored in the 9400's integral EEPROM. It also performs digital temperature compensation of the 9400s to reduce thermal errors by a factor of ten or more over conventional sensor compensation. The microprocessor also facilitates off-line rezero and span calibrations to maintain optimum sensor accuracy. This turnkey approach to all-media pressure measurements provides system static accuracy of up to ±0.05% FS.
The 9022 can sample using up to three concurrent scan lists at continuous rates exceeding 100 measurements per channel per second in engineering units. Pressure data in engineering units is output through an Ethernet 10 BaseT interface using industry standard TCP or UDP protocol. 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 9022 All-Media Intelligent Pressure Scanner is one component of the NetScanner™ System. Multiple NetScanner components measuring a variety of parameters and sharing the same command set can be networked to form a distributed intelligent data acquisition system.

- For channels measuring voltage inputs, measurements made from -FS to 0 VDC are specified at twice the error specification for the related range.
- Worst case at maximum tarnsducer load.

9022 Version 2.45 Release Notes
Last Released Version: Version 2.44
Version 2.45 Changes
- Improved TCP/IP reliability. The host must however wait 10 seconds after closing a connection before attempting to open a new connection.
- Enhanced temperature voltage calibration.
Command Summary:
- New commands:
- Set temperature gain reference coefficient: The ‘v01118 dddd..dddd’ command sets the gain reference coefficient used for the temperature signal where dddd..dddd is type float (follow this command with the ‘w07’ command to make the selection non-volatile). Example: v01118 .99999 sets the reference coefficient to .99999.
- Query temperature gain reference coefficient: The ‘u01118’ command queries the temperature gain reference coefficient.
