LEDs with adjustable threshold provide a visual alarm

Electronic & Software compatibility between F2000 Sr. & Jr.

32 channels – F2000 Sr.; 16 channels – F2000 Jr.

F2000 Jr. specially designed for hard to reach areas

New Design Features

Sensors and electronics

High sample rate for greater resolution of smaller flaws

Precisely matched sensors assure uniform channel response

Utilizes DSP technology for more in-depth, online processing

Electronics package with surface mount technology and

Miniaturized PC boards inside floor scanner

Alarm system

Protected LED Threshold alarms

Brighter, easy to see alarms

Alarm indicates when scanner is pushed too fast (to ensure speed control)

Wheels and suspension

8 large diameter wheels (3"/76.2mm dia)

Wide wheel base for increased stability

Double wheel axle design for heavily pitted topside and non-level plates

Chemically resistant wheels are designed to suppress vibrations and roll over debris without

sustaining damage

Maneuverability and Integration

Fixed wheels provide more stable and straighter scans

Detachable fixed stainless steel push handle for more control

Operation by one individual

Notebook PC mounted to handle

Software for the Storage Tank NDT System TT-F2000 Mark II Sr/Jr

Filters optimized to reduce background noise and enhance flaw signals

“Quick View" feature to simultaneously view phase and amplitude for easy flaw discrimination

Windows-based display program with embossing and 3-D rotational view capabilities

The top screen shows 3-D rotational image movable with program controls or with mouse; bottom shows line plot side view for 32 channels.

Detection Capabilities

Topside and Bottom side defects evaluated in a single scan

Detects 1/8" (3mm) diameter pits 50% deep on 1/4" (6mm) plates

Detects as low as 5% wall thinning

Clearly separates flaws from liftoff signals using the “QuickView" software

Detects flaws through nonmagnetic coating with thicknesses up to 1.00" (25.4 mm) *

Resolution may be compromised with thicker coatings

Options

Encoder: An electronic wheel feeds distance and speed information into the collection and display software for locating and mapping flaws

Mapping software: Takes plate dimensions input by user and draws entire tank floor (with the help of AutoCAD LT or Turbocar and the encoder data, the software plots each flaw seen by theF2000 System at the corresponding spot on the tank floor where it occurred)

Batteries: Two 12V batteries provide 10 hours of operation

Battery Charger: A dual battery charger can charge batteries overnight for a full day of power needs

F-2000 Jr.: 16 channel hand held scanner with wheels, for hard to reach areas such as sumps, annular rings, roof supports, and buckled areas

User friendly menu driven functions

Special real time signal processing algorithms

Real time 3-D display in full color

Rotating view for seeing hidden flaws

C-scan type overhead view shows defects for easy detection

Encoder data displayed for distance and location plots

Digital filtering for signal manipulation while preserving raw data

Zooming algorithms for detailed views

Uniquely separates pitting from gradual wall loss or gradual wall loss from pitting, by suppressing one or the other (see insert)

Shows wall thinning in percent loss or inches/mm remaining



Full screen view of calibration plate data for pits of 1/8” (3mm) to 1/2” dia. (12mm)	Zoomed up view of calibration data for 5/16” (8mm) pits 75%, 45%, 60% (first row) and 1/4” dia. (6mm) pits 60% and 30% (second row)
