The EPOCH 600 provides excellent quality ultrasonic perfor-
mance. Based on the same digital architecture as the EPOCH XT,
LTC and EPOCH 1000 Series, the EPOCH 600 provides flexible,
powerful pulsing and receiving features to accommodate the
needs of most flaw detection inspections.
Pulser/Receiver
The EPOCH 600 comes standards with powerful flaw detection
capabilities, such as:
• PerfectSquare ™ tunable square wave pulser
• Digital high dynamic range receiver
• Eight 100% digital filter sets
• Auto or manually adjustable PRF from 10 Hz to 2000 Hz
• Pulser voltage from 100 V to 400 V
• Amplitude resolution to ± 0.25%
• Five customizable digital measurements
Optimized Access to Powerful Features
Knob
The adjustment knob on the EPOCH
600 is used along with the CHECK
and ESC keys to adjust parameter
values in either coarse or fine incre-
ments. You have the ability to lock
the knob to prevent accidental pa-
rameter value changes during an in-
spection. This configuration provides
smooth value slewing for customers
who prefer adjusting parameters us-
ing a knob. The knob configuration
is designed to meet the requirements
of IP66.
Navigation Pad
The EPOCH 600 navigation pad is a
hallmark feature of the EPOCH flaw
detectors. The up and down arrows
on the navigation pad are used for
coarse parameter adjustment, and
the left and right arrows for fine
adjustment. The navigation pad also
contains additional functions and
frequently used parameters such as
gain, save, and the CHECK and ESC
keys. The navigation pad configura-
tion is designed to meet the require-
ments of IP67.
Options for Comfortable Navigation
In order to accommodate different user needs and preferences, the EPOCH 600 is available in
two hardware configurations: one with an adjustment knob and the other with a navigation area
on the keypad. The adjustment knob and the arrow keys on the navigation pad are responsible for
parameter adjustment and value slewing.
Standard Software Features
Dynamic DAC/TVG: Calculates signal amplitude as a percent-
age or decibel level compared to a DAC curve or a reference
echo amplitude fixed at a time-varied gain. DAC versions include
ASME, ASME 3, JIS, and Custom. Also includes several key fea-
tures: dynamically adjustable DAC curves, switchable DAC and
TVG views, and custom DAC warning curves.
DGS/AVG: This flaw sizing technique allows echo signals to be
evaluated with a DGS/AVG diagram associated to a particular
type of probe and material. The DGS/AVG diagram illustrates the
relationships between echo height, flaw size, and distance from
the transducer.
Curved surface correction: Corrects sound path information when
using an angle beam transducer to circumferentially inspect a
curved surface for either tubular or bar inspections.
