How the Thermal Imager Works and Thermal Imaging Buyers Guide

Thermal Imaging - Here's how it works:

A special lens focuses the infrared light emitted by all of the objects in view.

The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram. This information is obtained from several thousand points in the field of view of the detector array. 

The thermogram created by the detector elements is translated into electric impulses.

The impulses are sent to a signal-processing unit, a circuit board with a dedicated chip that translates the information from the elements into data for the display.

The signal-processing unit sends the information to the display, where it appears as various colors depending on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image.

How the Wahl Thermal Imager Works

Thermal Imaging is a technique for creating an image of a scene based on the invisible thermal radiation emitted from an object. Using this technology, thermal images of faults in mechanical or electrical plant can be displayed.

Thermal imaging can be used in any process where the temperature of the object gives an indication of its state not visible to the eye. For example, a loose electrical connection or a worn bearing will heat up. These defects can be seen with a thermal imager as a 'hot spot'.

The ability to measure the temperature of an overheating component enables the operator to determine the seriousness of the fault, and take corrective action before costly breakdown occurs.

Fluke 1AC-A1-II Volt-Alert Customer Reviews

By Elixirgy (California)

I work in a remodeling business, and this is an indispensable tool. I repeat, indispensable. The tip simply lights up when you touch it to the "hot" side of a Romex wire, instantly telling you if a wire is live or not. "Is this switch/receptacle that I'm about to take apart and work on/touch hot??" Well, now you know. It is important to use it for what it's designed for. It will not tell you if there is an open neutral or anything of the sort, so it's only good for minor troubleshooting (you'd need a Knopp, or something more specialized for that). If anything, it will err on the "hot" side. I.E: It will occasionally tell me a line is hot when it isn't (if there is allot going on in a box, or near dimmers etc.), but I've never had it tell me a wire was NOT hot, and get zapped by it (unless you touch the neutral side of a romex, but that would be your fault for not checking both sides of it! : )

So, for everyday work in the remodeling world, tracing wires, eliminating, and adding switches and receptacles, it can't be beat. It's tough, handy, quick and useful. A++

By E. Cole

Fine quality tool typical of Fluke.

The switch on this tester is much better than that found on the Greenlee tester. I am often working in cramped, dark areas and require a solidly built tester that doesn't suffer from inadvertent switch movement-a problem with the Greenlee and similar devices.

This tester, like every other non-contact (NC) tester I have used, will occasionally provide a "false positive" indication. This is often caused by an errant voltage present on a cable which is laying near an energized cable. This is due to inductance is is probably unavoidable with a NC device.

This is one of the best tool investments you can make-absolutely essential for electrical, plumbing, remodeling, or demolition. Work safely; always test it on an energized conductor and verify proper operation before use on unknown cables.

Highly recommended!

Car oxygen sensor replacement Data

How To Replace Oxygen Sensor
Ok, so you want to know how to replace your oxygen sensor eh? That's understandable. If you have been told that your oxygen sensor is bad or faulty, it will need to be replaced, and what better way to do that than by doing it yourself. Most mechanics will call this the DIY method, and it can be done with a few basic tools.

What you will need:

*An adjustable Crescent Wrench
*A Flat tip Screw Driver
*A New Oxygen Sensor

Now, because this is an article written on the general process of removing an oxygen sensor, remember that each vehicle is different and could have other things that need to be removed or replaced along the way.

Step One: Locate your Oxygen Sensor

On most vehicles, you will find your Oxygen Sensor located on your exhaust somewhere. On front wheel drive vehicle you will often find it on the front side of the engine when you open the hood. On rear wheel drive engines you will most likely find it located under the car right below the donut gasket. more

Car Oxygen Sensor Solutions
Virtually every car produced since the early 1980s contains a sensor that regulates oxygen flow to your engine. The oxygen sensor works by sending information to your vehicle's engine management system to help your car fun efficiently as well as to reduce noxious emissions. When an oxygen sensor fails your vehicle will run less effectively and devour more fuel. Thus, when oxygen sensor failure has been determined the sensor must then be replaced, a costly proposition if you rely on a garage to do the work for you. However, replacing an oxygen sensor is a task that you can do yourself, thereby saving you precious time and money. Let's take a closer look at just what an oxygen sensor does and the steps you can take to do the work yourself. more

How to Replace Your Car's Oxygen Sensor
The oxygen sensor (O.S) is a part of modern day electronic fuel injection systems and is essential in helping determine the precise amount of fuel needed for the engine to run efficiently. When this sensor fails, the vehicle will run in "open-loop" mode and will cause the vehicle to run much richer than necessary, which will waste more gasoline than is needed. It works by comparing ambient air with the amount of air inside the exhaust and then informs the engine control unit how rich or how lean the engine is running. The engine control unit can then command the fuel injectors to inject more or less fuel in the engine. It fails over time due to soot that coats the part and skews the reading. Another problem area in modern sensors is the (OS)heater. more

Car Oxygen Sensors Data

Bad Car Oxygen Sensors
On most all gasoline powered cars and trucks manufactured since the late 1970's there is a very small yet very important part that is located in the exhaust stream, known as the Oxygen Sensor. It is commonly referred to by automotive technicians as the O2 Sensor. This little part looks like a spark plug in a way, as it is threaded on one end, but it has a wire with a connector on the end opposite the threaded end. The threaded end is screwed directly into the exhaust stream on the engine side of the catalytic converter. more


Optimizing Fuel Economy With Sophisticated Pontiac Car Oxygen Sensors
Automotive engine is a complex arrangement of system of machine operations that aims to establish fuel efficient operations. Designed to deliver powerful engine performance, Pontiac rides have been engineered to impress you with its great navigation and driving safety capabilities. By incorporating the use of advanced automotive engineering, your Pontiac investment surely meets your performance expectations. The secret to its unmatched riding and driving quality lie on the functionality and service of its electronic engine sensors. Engine sensors are employed to effectively keep you posted on the actual working conditions of your engine and its components. With computer assisted engine assemblies, electronic sensors are automated so timely adjustments to critical factory performance settings will be made. To continually enjoy fuel efficient combustion operations, your engine is equipped with top of the line Pontiac Oxygen sensor application to maintain excellent fuel efficiency status. As the name implies, it precisely measures the oxygen proportion of your engine’s yielded air-fuel ratio. Because the date is the most accurate way of determine how clean and efficient fuel is burnt, engine sensors are directly wired to the engine control unit (ECU) where necessary adjustments to combustion operations is determined. This way, the metered amounts of fuel delivered by fuel injection system is immediately adjustment to have lesser emission and therefore less fuel wastage. more

Tips for Recycling Your Car Oxygen Sensor
Car Oxygen sensors are found in the exhaust system of cars, where they're exposed to fuel and other toxic gases such as HC, CO and NO2. These substances can pollute the sensor and hinder its capacity to work efficiently. Oil, fuel and coolant contamination can cause damage as well. Excessive soot buildup in the sensor's ceramic parts can increase response time and consequently decrease its capacity to detect oxygen efficiently.

The presence of lead in poor quality gasoline also decreases the life span of oxygen sensors. Exposure to silicates and silicones also hinders their ability to function correctly. Because the sensor's function is to determine the best ratio of fuel and air mixture in the car's exhaust system, contamination can cause the gas combustion engine to run rich (with unburnt fuel) or lean (with excess oxygen). This can decrease the car's mileage. more


Accurate Air-fuel Ratio is Done by the Saturn Car Oxygen Sensor
Modern cars today have been equipped with the genius of the oxygen sensors. Saturn, a car company that is young at its early twenties, has proved its rightful place in the automotive industry by producing high-quality oxygen sensors. They have developed these complex components through the innovative car technology that reflects in their resume as a car company. Thus, their Saturn Oxygen Sensor promises only accurate measurements of air-fuel ratio to further help the driver with his car's needs.

The Saturn Oxygen Sensor is a part of the emissions control system and feeds data to the engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. A gasoline engine burns gasoline in the presence of oxygen. It turns out that there is a particular ratio of air and gasoline that is ""perfect,"" and that ratio is 14.7:1 (different fuels have different perfect ratios---the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). more

The Car O2 Sensor and You: Why You Need
Them Modern vehicles are much more complex than their predecessors. Numerous additions have been made to increase fuel economy, as well as to decrease emissions. One of these things is the O2 sensor. All modern cars have at least one sensor, though most have two and several have four sensors. These sensors are located at various points in the exhaust system and play a vital role in both fuel economy and emission regulation.

For the tuner, Car O2 sensors can be huge pain in the behind. Custom exhausts are a great way to add power and performance to your vehicle. Unfortunately, you can find yourself without a place for your oxygen sensors if you don't buy the right type of pipes and headers. Typically, one sensor will be mounted on the exhaust manifold gasket (which is replaced by the header) and the other will be placed midway down the exhaust pipe, usually just before the catalytic converter. more

The Real Deal with Oxygen Sensors
An oxygen sensor is a vital part of your Suzuki vehicle. After all, it is mainly one of the important parts responsible for keeping a vehicle’s gas mileage low. According to manufacturers of oxygen sensors, this part of the vehicle is one of the key components of the total performance of a vehicle. more
