Bad Oxygen Sensors

Author: Monty Carlos
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.
This little component is the most neglected part on most vehicles, and is responsible for a myriad of engine performance and drivability issues, as well as poor gas mileage when it goes bad. If you own a gasoline powered vehicle and you know that this little gem has not been changed in the last 40,000 miles, no matter what make or model you have, just change it. You'll be glad you did.
The Oxygen Sensor is the heart and soul of all computerized fuel delivery systems. The Oxygen Sensor does just what its name states, it senses the oxygen content in your engines exhaust. It measures the oxygen level coming out of the exhaust and sends a signal to the vehicles computer that will in turn send a signal to the fuel injectors, telling them to pulse more fuel to go richer, or to pulse less fuel and go leaner. It simply makes sure that your engine is attaining complete combustion of the fuel by maintaining a 14.7:1 air to fuel ratio. When this happens the only thing that should come out of your tailpipe is Oxygen and Water, which are the only byproducts of complete combustion.
Whether you are a novice mechanic that likes to change your own parts, or you're the type of person that has a mechanic that takes care of your issues, do not overlook this inexpensive part. And if your gas mileage isn't what it used to be, or your engine surges and hesitates, change the O2 Sensor whether your think it's bad or not before you do any other expensive diagnostic testing, because 9 times out of 10 it will fix your problem. Be sure to change the oil right after installing a new O2 Sensor, as if the sensor was bad and the engine was running rich, then your crankcase will surely have a lot of fuel mixed with the oil.

Safety Sensors

Author: Leon Cowper

Technological developments are making the use of safety sensors in our household appliances more common and compulsory. The popularity of these sensors has been in its turn increasing their capabilities and rendering them more economical.

Usage of sensors in day to day household appliances

Believe it or not, safety sensors are being used all around you for various safety detections. Washing machines incorporate it to ensure safe washing process. Temperature sensors are used in the kitchen. Magnetic sensors are used for detecting limits. Gas sensors are used to detect any leakages well in time. Then there are pressure sensors, position sensors and even UV sensors. These find usage in different ways in our day to day life, in order to protect you from any incidental or major hazard.

Role of sensors in improving household appliances

Increasingly, experts from all fields, including engineers, technicians, developers and scientists, are focusing on possible usages of modern sensors in household appliances. Any developments in this connection would result in safer, more efficient and more intelligent machines. The underlying objective would remain to simplify the process and make the user experience comfortable, safe and wasting the least amount of energy and relevant resources. Of course, the concern of motor protection is also there. For example, the research goes on to improvise washing machines so that they use less detergent, less water and less electricity. The machine provides excellent results in the safest manner and for a longer time.

In the end, modern sensors are an advantage of technology that detect any unsafe conditions and give necessary signal so the user stays safe from any harm. Look up www.control-logic.com.au for safe, economical and reliable safety sensors.

Thermal Imaging Scope - FLIR Thermalvision

Author: Arthor Pens

A thermal imaging scope has a wide range of uses and this technology is currently being utilized in areas such as fire fighting, power line maintenance, building construction, the military and even in some luxury cars. A thermographic camera can be very similar to a modern camcorder in both operation and appearance and enables the user to see in the infrared spectrum. This technology will detect temperature changes in objects as well as heat patterns. A thermal imaging scope us useful in helping to discover problems before they become too costly for repair and can also be used to monitor existing problems allowing vital maintenance to be scheduled at convenient times. Many cameras equipped with a thermal imaging scope have the ability to record as an option, allowing for later viewing.

Fire fighters often use a thermal imaging scope to enable them to see through smoke which save precious time when attempting to find people in burning and smoke filled buildings. It can also be useful in localizing the base of a fire. Power line maintenance can be costly and dangerous if problems are not detected early. A thermal imaging scope enables power line technicians to locate joints that are overheating alerting them to signs of failure thus eliminating potential hazards.

A thermal imaging scope is a useful tool in the construction industry for detecting heat leaks. If thermal insulation develops faults, technicians can easily see these thermal signatures allowing them to improve the efficiencies of a cooling or heating system. The technology of a thermal imaging scope is also being used to enhance the safety of some cars. This system gives the driver vital visual information that goes well beyond the normal range of the typical headlamp as well as being able to see past the glare of on coming headlamp's giving the drive more time to react to potential hazards. The maintenance of electrical and mechanical systems in industry and commerce are greatly enhanced by using the technology of a thermal imaging scope. Capturing images, using the camera settings, can detect problems such as steam traps in heating systems enabling technicians to conduct repairs in a time and cost effective manner.

A thermal imaging scope is widely used in the military and other protection agency services. It has many positive useful applications in the areas of homeland security and defense, law enforcement, tactical military operations, border and coast patrol, anti-terrorism, nuclear and critical facility surveillance to name but a few. There are numerous models of cameras that come equipped with a thermal imaging scope such as the SPI Flir thermalvision camera scope which is compact and state of the art in thermal image viewing. It is a completely weather resistant system and utilizes US military standard eye cups. Other models can compensate for most any environmental conditions by using a unique scope with a floating reticule. Features such as digital zoom and user interface make these cameras a strong and sound piece of equipment in many surveillance applications.

The technology used in a thermal imaging scope has many useful applications in a wide range of areas such as homeland security, policing, industry, commerce and personal uses such as hunting. Cameras equipped with a thermal imaging scope are now compact, user friendly and extremely versatile.
