All You Need to Know About a Digital Tire Pressure Gauge
All tires need a certain amount of pressure to operate properly. This is usually prescribed by the car manufacturer. Under normal conditions, it is possible to maintain a constant air pressure inside the tire, as long as there are no defects in the tire and the external weather conditions do not change.
A tire pressure gauge is a device that can measure the air pressure inside a tire. Damaged, old, or worn out tires tend to lose their air pressure fairly quickly. Therefore, investing in a tire pressure gauge is a great way to make sure that you always have the optimum air pressure in your tires.
Setting the correct tire pressure is virtually a science. While the recommended factory settings will work out great for normal day-to-day driving, in more competitive conditions, improper tire pressure can have wide ramifications. In most competitive motorsports, for example, a lot of attention is given to the air pressure in the tires at any point during a race as the tire pressure can have a significant impact on the vehicle's performance and fuel efficiency.
A digital tire pressure gauge consists of a digital readout (i.e., LCD screen), at one end, and a valve that matches the tire valve at the other end. When it is placed over the tire valve, the air inside the tire exerts a force on the device. This force is converted into a numerical value and displayed on the screen.
Digital tire pressure gauges tend to be very accurate. The error range in some models is as low as +-0.05 psi over a range of 5-150 psi. While these can be fairly expensive, investing in one can save you a lot of money over the long run as your car's performance and fuel efficiency, not to mention tire life span, will improve significantly if you maintain the optimum tire pressure as recommended by your car manufacturer.
Digital tire pressure gauges tend to come in a wide variety of shapes and sizes. Because of their digital nature, they can be molded into any shape. When you're out shopping for one, make sure to get something that is ergonomically designed and is easy to handle and use. If you have poor eyesight, get something that has a large LCD screen with clearly visible readings. It is also wise to go for a model with a backlight, as you might have to use the device in the dark or in bad weather conditions.
A battery powered pressure gauge is recommended over one that is powered by an electrical unit as you can toss the battery powered device into your trunk and use it outside your garage. Always remember to keep an extra set of batteries handy.
A true auto-enthusiast might want to go for a model that will allow him to connect it to the air compressor valve and the tire valve simultaneously. This will let you adjust the tire pressure as you read it, saving you oodles of time and effort.
There is a wide variety of models when it comes to picking a digital tire pressure gauge. You shouldn't go over the top and pick up a fancy $200 model. Just get something that is within your budget and is accurate enough for your needs.

The Best of Industrial Valves & Pressure Gauges 101
Valves are an integral part of the day-to-day functions- plumbing valves used in taps for hot and cold water, gas control valves on cookers and barbecues, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.
Valve is a device that regulates the flow of gases, fluidized solids, slurries or liquids by opening, closing or partially obstructing various passageways. Industrial Valves are used in a variety of commercial, residential, military applications, and also in transportation. Oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing constitute the majority of valves used by industry. These may be operated manually, or automatically, driven by changes in pressure, temperature or flow. Based on the varying needs, valves may be of different types.
- A eck valve llows fluid to flow through it in only one direction. Check valves are two-port valves, that is, they have two openings in the body, one for fluid to enter and the other for fluid to leave.
- Ball Valves are principally designed as on/off isolation valves for a wide range of temperatures and pressures; they have inherent quick opening flow characteristics. Specially designed ball valves however, may offer good flow control capabilities at high pressure.
- Butterfly valves are for quick turn on or Shut Off applications including agricultural and irrigation, water distribution and waste treatment. Industrial applications including chemical, paper and pulp, and a wide array of industrial mediums.
- Gate valve are commonly used in many garden, irrigation, and industrial flow control systems.
There are a wide range of industrial applications in which Pressure Gauges are utilized. Pressure Gauges are designed to measure the pressure of a gas or liquid. These instruments monitor and indicate the internal pressure and/or vacuum of vessels and systems, especially those having dynamic working characteristics that require regular monitoring. These vary in style, size, pressure ranges, and wetted parts material, depending on the application. Specialty tanks, such as fire extinguishers and medical gas cylinders use pressure gauges. The important types include:
- Liquid Filled Pressure Gauges can be filled with various fluids, such as silicone oil, mineral oil and glycerin. The liquid filling provides protection to internal components of the gauge in severe environments in which the gauge may endure excessive vibration and pulsation. Gauges made of stainless steel can be used in corrosive environments or in applications that have strict sanitary requirements and are capable of withstanding high pressure cleaning.
- Industrial Pressure Gauges have heavy-duty sensing elements and case designs and higher accuracy requirements than general purpose utility gauges, and are built for extended life, designed for harsh, corrosive environments.
