Most of our industrial mechanical systems are run through hydraulic pressure. For example you might have seen huge hydraulic press in some industrial units which are used to press different items. These are run by hydraulic pressure. Similarly, you may have seen the car lifters in motor workshop or motor service pumps. These hydraulic lifters can lift the large forks to a desirable height. The mechanic thus lifts your vehicle up to desired height for different maintenance jobs. This elevated position of your car enables him to work on the lower body of the vehicle which he cannot approach without lifting the vehicle to a certain height.
Also you may have seen some kinds of air pumps. Electrical motors are mounted on the top of ironic cylindrical body. Air is filled in the tank with the help of electric motor which enable pump to work. The cylinder is made up of iron and the edges are electronically welded. Each cylinder has its specific capacity to accommodate air pressure. To judge that capacity of cylinder, some type of gauge is used which is known as hydraulic measuring equipment. This device helps you fill the cylinder to a specific level by viewing reading from the gauge.
All the above examples explain importance of pressure measuring hydraulic gauges. If there were no such instruments installed with the above set ups, you could not be able to judge the air pressure thus leading to some unwanted incidence. A hydraulic gauge is usually a small round shaped instrument which is equipped with a dial and one or two needles pointing to different levels mentioned on the dial. The pointing needles move with increasing pressure and thus you can judge the inner pressure. There are a number of hydraulic pressure measuring equipments available in the market. You can select one according to requirement of your job.
