Pressure Systems rackmount version of its highly successful NetScanner System features the latest generation Model 98RK-1 Scanner Interface Rack and Model 9816 Pneumatic Intelligent Pressure Scanners for ultra high speed scanning of multiple pneumatic measurements in turbomachinery testing.

The enhanced Model 98RK-1 rack utilizes a high performance switch enabling the 9816 scanners to communicate with the host computer via an auto-negotiating 10/100/1G Base T Ethernet interface. The rack also provides power and pneumatic connections for up to eight internally-housed 9816 scanners. Additionally, the 98RK-1 can provide power and communication for up to three external NetScanner System components such as PSI’s Model 9022 for all-media pressure measurements or Model 9032 for high-accuracy barometric or reference pressure measurements.

Model 9816 scanners integrate 16 silicon piezoresistive pressure sensors of any pressure range with a microprocessor. 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, and user-managed last or next 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 sensor data to correct for zero, span, linearity and thermal errors. It also performs digital temperature compensation to reduce sensor thermal errors by a factor of ten or more over conventional compensation. The microprocessor also controls the actuation of an integral manifold to execute on-line zero calibrations 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.

Each 9816 can sample using up to three concurrent scan lists at continuous rates up to 100 measurements per channel per second in engineering units. Pressure data is output over the Ethernet interface supporting both TCP and UDP protocols. The NetScanner System 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 9816 scanners using NUSS.

The NetScanner™ System is an array of system components measuring a variety of parameters and sharing the same command set that can be networked to form a comprehensive distributed intelligent data acquisition system.

Section 1.3.2 Manifolds and Pressure Connections

Add the following NOTE to the paragraph:

"9816 scanners with front-mount quick disconnect (QDC) panels have all necessary input fittings on the panel. Therefore, the run reference (RUNREF) input ports on the rear of the 98RK are not utilized. Previously, compression fittings were installed in these rear ports. The input ports now have plugs, rather than fittings, installed.

Paragraph (4) should read;

Slide the front panel forward as far as it will go (approximately d").

Page 5-16Section 5.1.6.2 Tubing Plate O-Ring ReplacementAdd a new paragraph (5) to read as follows:

"Inspect for the presence of optional shim washers around each of the six (6) screws. If washers are present, retain for use in reassembly."

Renumber remaining paragraphs accordingly.Change paragraph (7) to read: (additions are in italics)

Examine the tubing plate and calibration manifold to verify that no contaminants are on either surface. This generally requires microscopic examination. Replace the tubing plate by slowly placing the plate on the calibration manifold housing. Make sure the O-ring/cup seal side is down toward the pneumatic sliding manifold and the guiding pin on the calibration manifold housing fits into the mating hole of the tubing plate. Also, ensure that shim washers, if used, are reinstalled between the tubing plate and the calibration manifold assembly.

Section 5.1.6.6 Module Rear Manifold O-Ring Replacement

Paragraph (4a) to read as follows:For glued O-ring replacement (O-rings will be black)

(4a) There are only two O-rings on this panel that are glued; the larger black ones. One is for the purge port and the other surrounds a blanking pin. Using a glue syringe, line the O-ring cup(s) with appropriate glue, such as 3M Scotch Grip 1357. Insert a new O-ring (PSI part number 61-03-50120) and press it into the cup with your hand. Allow the glue to dry for approximately 10-15 minutes. Clean any excess glue with appropriate cleaning solvent, and dry. Be extremely careful not to allow any excess glue to cover the tubing ports.

Section 5.1.6.7 Rear Panel Quick Disconnect (QDC) O-Ring Replacement

NONE of the O-rings on this panel are glued. All are pressed into place over a flared center tube.
PSI part number for these O-rings is 61-03-4762. All O-rings are black.

Delete paragraph (6) and renumber the remaining paragraphs (6) through (10).
