Open your car's glove compartment, pull out your owner's manual, and look up “tires." You should find details including front and rear “PSI" listings. PSI stands for pounds per square inch. This number is determined by your vehicle's manufacturer, and it's how you can tell if your tires are properly inflated.PSI is based on your vehicle's:Total weight and size.Towing weight capability.Recommended ...

How to Check Your Tire PressureChecking tire pressure is easy. You can do it right at home or at the gas station. Just be sure you check the pressure when your tires are cold, or haven't been driven in several hours. This will give you the most accurate reading.The most important piece of equipment you need is an accurate tire pressure gauge. You can find battery-operated digital gauges, or more t...

Even brand new tires with minimal wear and tear lose air constantly. Factors that can affect tire pressure include:Hot or cold temperatures.Driving distance.Towing or carrying added weight in your vehicle.Most tire and vehicle manufacturers recommend checking your tire's pressure each month, as they can lose multiple pounds of pressure within that time from simple daily use.In addition, it's impor...

According to the National Highway Traffic Safety Administration, under-inflated tires have a higher risk of damage and failure. Not only will they wear out faster if under-inflated, but faster deterioration can also lead to reduced control of your vehicle, tire blowouts, and crashes.In addition to safety, there's also an environmental and economic benefit to keeping your tires full of air. Gas mil...

By checking tire pressure once a month, you'll get a good idea how they are performing. If your tires are fairly new and continue to leak air, you should consult your dealer or mechanic. You may have a faulty valve or other damage that is difficult to detect... which could unfortunately result in the need to replace the tires completely. But with proactive maintenance, you could catch an issue bef...

Bimetal thermometers rely on the principle that different metals expand at different rates when exposed to heat. By bonding two different metals together to make a bimetallic strip, it becomes more sensitive to small temperature changes. Most of the bimetal strips use high thermal expansion alloy like steel or stainless steel coupled with low thermal expansion ally such as Invar.Two construction m...

Digital pressure gauges use pressure transducers to provide a reliable, high accuracy reading on an attached digital display. Our display takes the signal from the transducer and processes it according to your settings to give you a pressure reading in the unit of measure of your choosing - adjusting it for activated features like tare or peak hold.Unlike analog, or dial, pressure gauges, digital ...

On a residential heating boiler the automatic water-feeder/pressure reducing valve that automatically provides makeup water to the heating boiler if pressure drops below 12 psi. So 12 psi is the typical "cold" pressure for residential boilers.If your building is taller than two floors, the installer may have needed to boost the starting "cold" water pressure for your boiler to overcome the hot wat...

Pressure and Temperature gauge on hot water or hydronic heating boilers: this gauge displays the heating boiler internal pressure and temperature.Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open.Typical operating temperature settings on a boiler call for a Lo...

Body temperature is a great indicator of something being amiss so it is important to know how to use a digital thermometer properly. Being aware of the necessary steps will help you to determine what type of illness that you are dealing with.Step 1 – PrepareEven if the digital thermometer has been stored prior to use, it is prudent to give it a clean before using it again. This can either be done ...

An electric thermometer uses electricity to measure temperature. An electric resistor known as a thermoresistor is the key to the electric thermometer. This sensor's resistance is changed by a fluctuation in temperature. A small computer calculates the change and converts the readout to temperature. This technology allows much faster temperature taking at the doctor's office as well as on a buildi...

The majority of boiler pressure gauges are defective or inaccurate.When dealing with boiler pressure problems, the FIRST thing that must be done is to verify the accuracy of the pressure gauge. A test gauge is easy to construct.What you need:1. A 0-30 (best) or 0-50 (OK) PSI pressure gauge. Higher pressure gauges are useless for this application as they lack the resolution needed for a proper read...

Bimetal thermometers use two strips of different metals to convert temperature into mechanical displacement. The different metals, often steel and copper or steel and brass, are joined together throughout their length and will expand at different rates as they are heated. He difference in expansion will cause the strip to bend one way if heated or the other if cooled. This movement correlates to t...

How is the water thermometer invented ?The water thermometer has been around for centuries, but not many people are aware of the origins of this instrument. The following is a brief synopsis of the origin and development of the water thermometer.OriginsThe first water thermometer was created during the 16th century. In the year 1593, Galileo Galilei did the existing thermoscope one step better and...

How to ensure that the water Temperature is just proper?There are pool heaters offered in the marketplace to preserve h2o heat in early spring and even into fall but how do we know we have the appropriate pool water temperature? Practically nothing can spoil your swimming pool celebration than dipping in chilly h2o but how warm must pool drinking water be? Pool water that is way too very hot is n...

Does it feel boiling hot to you today or is it just me? And how we can tell? If I say today's hotter than yesterday and you disagree, how can we settle the argument? One easy way is to measure the temperature with a thermometer on both days and compare the readings. Thermometers are simple scientific instruments based on the idea that metals change their behavior in a very precise way as they get ...

How to measure humidity?Before we can figure out how to measure something, we have to have an idea of what we're measuring—and what our measurements will mean. We measure most things in scientific units of one kind or another, such as kilograms, meters, or seconds; but humidity is slightly different, and we typically measure it in two quite different ways.One possible measurement is called the sp...

Bimetal refers to an object that is composed of two separate metals joined together. Instead of being a mixture of two or more metals, like alloys, bimetallic objects consist of layers of different metals. Trimetal and tetrametal refer to objects composed of three and four separate metals respectively. A bimetal bar is usually made of brass and iron.Bimetallic strips and disks, which convert a tem...

How to operate Bimetal Thermometer ?The temperature is measured with a bimetal system inside the thermometer stem. The bimetal system consists of two metal strips bonded together that have different expansion coefficients. Therefore, one strip will expand faster than the other causing the bimetal strip to curl in proportion to its temperature. The bimetal system is helically wound and heat treat...
