Mechanical Installations

In many industries, mechanical systems serve as the backbone

of operations.

Thermal data collected with a thermal imaging camera can be

an invaluable source of complimentary information to vibration

studies in mechanical equipment monitoring.

Mechanical systems will heat up if there is a misalignment at

some point in the system.

Conveyor belts are a good example. If a roller is worn out, it will

clearly show in the thermal image so that it can be replaced.

Typically, when mechanical components become worn and less

efficient, the heat dissipated will increase. Consequently, the

temperature of faulty equipment or systems will increase rapidly

before failure.

By periodically comparing readings from a thermal imaging

camera with a machine’s temperature signature under normal

operating conditions, you can detect a multitude of different

failures.

This thermal image shows an electric engine under normal operation.

Motors can also be inspected with a thermal imaging camera.

Motor failures like brush contact-wear and armature shorts

typically produce excess heat prior to failure but remain

undetected with vibration analysis, since it often causes little

to no extra vibration. Thermal imaging gives a full overview and

allows you to compare the temperature of different motors.

Other mechanical systems monitored with thermal imaging

cameras include couplings, gearboxes, bearings, pumps,

compressors, belts, blowers and conveyor systems.

Examples of mechanical faults that can be detected with thermal

imaging are:

• Lubrication issues

• Misalignments

• Overheated motors

• Suspect rollers

• Overloaded pumps

• Overheated motor axles

• Hot bearings

These and other issues can be spotted at an early stage with

a thermal imaging camera. This will help to prevent costly

damages and to ensure the continuity of production.

Electrical systems

Thermal imaging cameras are commonly used for inspections of

electrical systems and components in all sizes and shapes.

The multitude of possible applications for thermal imaging cameras

within the range of electrical systems can be divided into two

categories: high voltage and low voltage installations.

High voltage installations

Heat is an important factor in high voltage installations. When electrical

current passes through a resistive element, it generates heat. An

increased resistance results in an increase in heat.

Over time the resistance of electrical connections will increase, due

to loosening and corrosion for instance. The corresponding rise in

temperature can cause components to fail, resulting in unplanned

outages and even injuries. In addition, the energy spent on generating

heat causes unnecessary energy losses. If left unchecked, the heat

can even rise to the point where connections melt and break down; as

a result, fires may break out.

Examples of failures in high-voltage installations that can be detected

with thermal imaging:

• Oxidation of high voltage switches

• Overheated connections •

Incorrectly secured connections

• Insulator defects

These and other issues can be spotted at an early stage with a thermal

imaging camera. A thermal imaging camera will help you to accurately

locate the problem, determine the severity of the problem, and

establish the time frame in which the equipment should be repaired.

A wide view of a substation can quickly show areas where unwanted high

resistance connections exist. No other predictive maintenance technology is

as effective for electrical inspections as thermal imaging.

One of the many advantages of thermal imaging is the ability to perform

inspections while electrical systems are under load. Since thermal imaging

is a non-contact diagnostic method, a thermographer can quickly scan a

particular piece of equipment from a safe distance, leave the hazardous

area, return to his office and analyze the data without ever putting himself

in harm’s way.

Thermal imaging cameras allow you to inspect high voltage installations

from a safe distance, increasing worker safety.

Continuity is very important to utilities since many people rely on their

services. Therefore thermal imaging inspections have become the core of

utility predictive maintenance programs throughout the world.

Thermal imaging cameras are used for inspections of electrical systems and

components in all sizes and shapes and their use is by no means limited to

large high voltage applications alone.

Electrical cabinets and motor control centers are regularly scanned with

a thermal imaging camera. If left unchecked, heat can rise to a point that

connections melt and break down; as a result, fires may break out.

Besides loose connections, electrical systems suffer from load imbalances,

corrosion, and increases in impedance to current. Thermal inspections can

quickly locate hot spots, determine the severity of the problem, and help

establish the time frame in which the equipment should be repaired.

Examples of failures in low voltage equipment that can be detected with

thermal imaging:

• High resistance connections

• Corroded connections

• Internal fuse damage

• Internal circuit breaker faults

• Poor connections and internal damage

These and other issues can be spotted at an early stage with a thermal

imaging camera. This will help to prevent costly damages and to avoid

dangerous situations.

Whether you intend to use thermal imaging cameras for

low voltage inspections in production plants, office facilities,

hospitals, hotels or domestic residences, FLIR Systems has

exactly the right thermal imaging camera for the job.

The BTU07 is a full featured and low cost BTU meter with Modbus over RS485 capability developed specifically for sub metering applications. The DFSR737A is unique among BTU meters by having the BTU calculator separate from the flow sensor, which allows the flow meter to be installed where it is needed, but with the BTU calculator and display installed anywhere it is convenient for tenant reading. The BTU07 comes as a set together with the flow and temperature sensors.
