If you run a processing business, you may have a lot of equipment, and some are probably very sensitive to pressure. For example, when liquids get hot, they boil, but in an enclosed system an enormous amount of pressure can build up. In fact, in some cases, the possibility of an explosion is very real, and it is vital to monitor these conditions closely and constantly. Anderson instrument distributors can give you both analog and digital pressure sensors but which one is the best choice? Here is more on the subject to help you make an informed decision.
Analog
Analog devices like gauges and scales have been around for over one and one-half centuries. In the 19th Century, pressure gauges and pressure relief valves were extremely important to business running steam driven equipment. For a long time, steam engines were the norm until gasoline and diesel engines finally took over.
Analog gauges from Anderson instrument distributors use Bourdon tube technology. This kind of tube is curved, and it straightens out as pressure gets applied. The tube is connected to a device with a needle, and it moves in a circle, each mark on the gauge denotes a certain amount of pressure. Analog pressure gauges are simple yet accurate.
Digital
Digital pressure gauges use pressure sensitive elements. As they sense pressure, they send a digital signal to a control unit. Digital means numbers, and it is the language computers use to store and process information.
Digital gauges are very accurate and are often used in control systems. They can measure pressure readings from a remote location, and there are no parts to wear out, but they do require a power source. Some companies need both types of gauges. Talk to your Anderson instrument distributors about your pressure gauge needs. They are there to help you choose the right instruments and equipment for your business.
