				Data Logger View

The Nova 900 Series Precision Ultrasonic Thickness Gages represent the latest release and a dramatic advancement in portable ultrasonic thickness gages. A proprietary monolithic integrated circuit chip and a highly advanced microcomputerized design have permitted the achievement of performance levels considered only conceptual, The outgrowth of this technology has been the development of 3 portable models an 2 Benchtop in the Nova 900 Series. These ruggedized, highly stable models have been carefully designed to offer a choice of features to best suit the application level, gaging environment and user preference. All five models provide the identical base gaging performance, with variations in options and the supporting features. The Nova 910 and 950 incorporate a backlit LCD menu display AND a bright LED numeric display which improves view ability at a distance. The 910 is a basic gage emphasizing operational simplicity for the more straightforward, less demanding applications. The Nova 950 offer a wide variety of supporting features including 50,000 point Data Logger, User setup parameters can be modified and stored, High/Low alarms, Industry First Scan Bar, Scrolling 'B' Scan and more.

*AutoSet...patented*

AutoSet... Incorporated Into All Models AutoSet is the most outstanding feature ever designed into an ultrasonic thickness gage. It automatically recognizes the transducer which has been selected for a given application and then automatically sets all corresponding circuit parameters for peak performance... WITHOUT expensive 2 or 3 pole custom cables.A simple and easily available BNC probe cable is all that is required. AutoSet's elaborate software program issues digital commands to optimize and properly set the pulser characteristics, transducer damping and zero (autozero), receiver characteristics, a host of logic and gating functions, the thickness readout range (autorange) and gaging precision. Another program, operational during calibration, even "recognizes" the basic class of material being gaged and automatically refines the measurement accuracy. *Velocity control:* Calibration is performed by either entering the know ultrasonic velocity for the material being gaged or by setting up on a known thickness of the material. Conversely, material velocity can be measured for material of known thickness.

Advanced Pulser / Receiver

Featured is a highly advanced pulserreceiver system which operates under automatic microprocessor control. AutoSet commands the pulser/receiver to set the proper balance between system sensitivity and bandwidth for each selected application (transducer). The receiver's design includes digitallycontrolled AGC (automatic gain control), DAC (distance amplitude correction) and polarity. A unique dual pulser circuit substantially enhances performance, The net result is remarkable resolving power for thin materials and exceptional penetrating power

Power is provided by both a rechargeable 'AA' batteries ( user replaceable via back panel) and a universal AC plug in adapter. A power divider circuit permits the AC adapter to independently power the gage, as well as simultaneously charge its battery pack. Thus, continuous operation is always assured from an AC line source, regardless of battery condition or charge level. A battery low charge level indicator is included, while a power cutoff circuit automatically protects the battery pack from unintentional over or discharge. Also to conserve battery charge level, the gage automatically turns itself off if not used after a short time.

	Extra Modes: Select from factory preset setups or Modify & Save up to 30 user definable setups or let AutoSet do the work! Industry's First ScanBar displays an analog representation of current thickness The Delta mode; plus and minus variations from a selected nominal thickness. The industry's FASTEST Responding, Adjustable HI/LO Alarms can be set, even activating a front panel LED in an optional Alarm Light Transducer. 500 Hz Acquisition Rate!! "TMin" displays the minimum thickness detected across a surface scan 500 Hz Acquisition Rate!!. The Modify mode stores up to 30 application setups in memory. 2 Point Cal Provides optimum accuracy where geometry may need to be considered Lock provides added protection against accidentally altering the controls. OnBoard Data Logger: Over 50, 000 thickness readings and locations can be stored in memory. The stored data can be sent through the USB or RS232C port to a computer.

Applications & Transducers

There are a broad array of Nova AutoSet transducers available for the Nova 900 Series. Rather than offer many thickness gages dedicated to various applications, the transducer actually sets a single gage to optimize for a given application. Transducers available include contact, delay line, bubbler, immersion as well as the ability to custom configure a probe to an application and assign it an AutoSet "channel"

Just a few of the applications supported include:
Chemical Milling, investment castings such as turbine blades for aerospace or power generation, wax castings, steel, aluminum, plastics, composite materials, fiberglass, rubber, cast parts and more...
