Bolt Gage 3 Features
Bolt Gage 3 Builds on the Best
Bolt Gage 3 offers all of the unique features of other Power-Dyne ultrasonic bolting products
in an improved system. From its improved package and ergonomics to expanded functionality
and ease-of-use, Bolt Gage 3 is better.
How Bolt Gage 3 Works
Bolt Gage 3 sends ultrasonic waves down the length of the bolt. Its microprocessor and
software analyze the returning echo duration and compare the information to a reference
value for the bolt. Bolt Gage 3 analyzes this information and displays bolt stretch, stress and
load. This method of measuring "tightness" is far more accurate than that of applied torque,
which is an indirect method subject to variables such as friction, lubricity, torsion and bending.
Bolt Gage 3 may be used during tightening for process control, or after tightening for quality
control and maintenance.
Fast, Easy and Automated
Bolt Gage 3 automatically adapts to different bolt geometry's by adjusting the receiver gain,
delay, threshold and polarity. Temperature compensation is also automatic. An integral
oscilloscope verifies your set-up with a graphic display of bolt echo. In fact, Bolt Gage 3 set-up
is the most automated in the industry.
Improved Data Management and Handling
Bolt Gage 3 stores information for up to 5,000 bolts on each removable data storage card.
Multiple cards provide virtually unlimited storage. Bolt Gage 3 file management has improved
with the availability of alphanumeric characters for project/bolt-typenames. Project file names
can be edited and individual project files can be deleted. An exponent key permits the use of
large values with minimal effort. Data and oscilloscope traces can both be printed to Epson or
compatible printers through an integral, modular RJ-45 quick-connect cable. Data can also be
transferred to and from personal computers for use in popular spreadsheet and database
Ergonomically Designed with Durability in Mind
In the field, at the lab or on the factory floor, Bolt Gage 3 stands up to the tough stuff. Its
microprocessor, electronics and oscilloscope are housed in a rugged, heavy-duty case with
sealed display. A tactile-responsive, sealed silicon rubber keypad protects the system in
demanding field and industrial environments. The swivel-locking carrying handle is designed
for ease of portability.
Programs with Built-In Bolting Expertise
Bolt Gage 3's patented operating system builds Power-Dyne's extensive bolting expertise into
software. Programs perform automatic field calibration to NIST (NBS) standards. Bolt tensile
calibration is standard. Accurate tracking into the "yield" region is also available. No other
system offers as much bolted joint expertise built into software. Our programs work the way
bolts do.
Transducers for Every Bolting Application
  • Power-Dyne offers a full line of standard transducers to allow magnetic coupling to a
    wide range of fastener sizes. Outside diameters range from .375 in. to 1.16 in with
    frequency ranges from 2.25 MHZ to 10 MHZ. Power-Dyne can also supply special
    design transducers to meet almost any requirement.
  • Power-Dyne's wide range of transducers may be attached with av ariety of methods.
    Magnetic, adhesive or mechanical attachment,in top or right-angle configurations, are
    all available. Standard and special cables are also available. A high temperature
    transducer may be used on joints as hot as 400º F (205º C) without cool-down. You can
    verify bolt loads at actual process temperatures.
Transducer Multiplexer - Makes One Bolt Gage 3 Work Like Sixteen
Power-Dyne's new transducer multiplexer and software can simultaneously monitor loads in up
to sixteen bolts from a single Bolt Gage. Additional multiplexers can be coupled to monitor
larger groups of fasteners. Special software combined with the multiplexer provide fully
programmable operation and storage or readings from up to sixteen bolts or more. The
system displays single or multiple bolt data in real-time. Multiple reference standards may be
used. Project data is automatically date-stamped and multiple-pass readings may be stored.
As with other Bolt Gage 3 programs, data can be transferred to and from popular PC-based
