The NetScanner™ System is a comprehensive, distributed data acquisition system centered
around PSI’s proven Intelligent Pressure Scanner technology. The rackmount configuration of
this system is comprised of Model 98RK-1 Scanner Interface Racks, each housing up to eight
(8) Model 9816 Rackmount Intelligent Pressure Scanners networked via the Ethernet
interface. The 98RK-1 chassis provides communication, power supply and pneumatic
connections to the 9816 scanners. The 98RK-1 utilizes an integral gigabit switch to connect all
scanners to a host computer. Each 98RK-1 can also provide power and communication to as
many as three (3) remotely connected NetScanner modules such as the Model 9116
Pneumatic Intelligent Pressure Scanners, Model 9022 All-Media Intelligent Pressure
Scanners, Model 9046 Intelligent Temperature Scanners, and Model 903x Pressure
Controllers. Refer to their respective datasheets for more information on these NetScanner
System components. A typical system configuration is shown in Figure 1.2.
Each Model 9816 Rackmount Intelligent Pressure Scanner module integrates sixteen (16)
silicon piezoresistive pressure sensors and a unique patented calibration manifold with an
onboard
32-bit microprocessor. This provides compensated engineering unit (EU) data output via
the Ethernet interface. Each pressure sensor is packaged with an integral EEPROM for storage
of calibration data unique to the sensor. Integrating the EEPROM within the sensor enables
simple ‘plug and play’ field replacement of transducers with automatic uploading of sensor data
during system power-up.
