Infrared & Ultrasound
Two Proven Technologies
‘To Help Keep Your Plant Running’
Increase your Equipment Reliability
with
Infrared Technology
What is Infrared?
Infrared is a form of electromagnetic radiation
Everything above -273 oC (absolute zero) emits infrared radiation
The heat we feel from the sun is infrared energy
Advantages of Infrared
Allows you to ‘see’ heat
Cost effective
Fast, non-invasive & safe to implement
Minimal downtime as a result of electrical and
mechanical problems
Effective prioritization of repairs
Improved employee safety
Energy savings
Wide range of applications
The Infrared Camera
The Infrared Camera sees the total energy emitted by an object
and translates it to temperature.
Infrared Image Interpretation
Emmissivity
Infrared Thermometer
A common misapplication of the
Infrared Thermometer relates to
its Distance-to-Spot Ratio.
The size of the laser spot is
not the size of the actual area
being measured.
A typical D:S ratio of 12:1 means
the area of measurement’s diameter is
1’ if you are 12’ away from the object
being measured.

Increase your Equipment Reliability
with
Ultrasound Technology
What is Ultrasound?
Human range (16Hz to 18KHz)
Industry Applied range (20KHz to 100KHz) is Heterodyned for
Audible Human range
Diagnostic Ultrasound is for Medical Imaging
Advantages of Ultrasound
Directional & Locatable
Useful in Many Environments
Early Warning Failure Indication
Wide Range of Applications
Supports Other Technologies
The Ultrasonic Probe
An Ultrasonic Probe hears electrical & mechanical problems as
well as airborne disturbances.

Underground Leaks
Ultrasonics along with Infrared
Imaging has successfully
located Floor Heating System
leaks embedded in 8” of
concrete
Heating loops were mapped on
floor.
The line was pressurized with
air to 50 psi so the Ultrasonics
could pinpoint the leak for
quick repair.
Valves & Steam Traps
Valves Effect Flow; Leakage
can effect the efficiency of
the system
Determine if the valve flow is
upstream or downstream
Test all types of valves, even
while operational.
Determine if a trap is
operating properly.

Ultrasonic Electrical Inspection
Inspect enclosed systems while
energized
Scan switchgear ‘before’ opening to
inspect with infrared
Prevent ‘Arc Flash’ injury

Arc Flash
Arc flash can kill.
There are many causes of arc flash. It can occur in
any electrical equipment regardless of voltage.
There are conditions, that produce the potential for
arc flash within enclosed cabinets, that can be
detected before flashover or arc flash incidents can
occur.
These conditions are arcing, tracking and corona.
Arc Flash Conditions
Corona
Only occurs at 1000V or higher, and is
undetectable by infrared inspection.
Tracking
Destructive dielectric breakdown that
results in a fault in the insulator.
Arcing
The main concern in low voltage
systems
