Everything is digital and computerized today. However, there is still a need for analog gauges and instruments and this why Anderson instrument distributors offer both selections. If you are in the processing business, you need accurate and reliable instruments. So, should you choose digital gauges or tried and true dial gauges?
Analog Gauges
Let’s examine a dial type pressure gauge for an example. The dials are simple and easy to read. Inside the gauge is a tube which is curved. When pressure is applied through the gauge, the tube begins to straighten out. This tube is called a Bourdon tube (named after its inventor). The end of the tube is connected to a mechanism and gear which turns a shaft, rotating a needle or dial on the face of the gauge. This type of gauge has been around since the mid 19th Century and is very accurate.
Digital
When you buy a digital pressure gauge from Anderson instrument distributors it may look very much like the Bourdon type. However, they are not the same inside and the mechanisms are quite different. Digital gauges utilize high tech sensors and a microprocessor which also works as a transducer. When pressure is registered, it is turned into a digital signal. Digital data is a series of numbers with one and zero and this is how computers read and store information.
What’s the Difference?
You’ll discover a major difference in price. Digital gauges are more expensive and they need a source of power (like a battery) to operate the sophisticated mechanism. anderson instrument distributors sell analog gauges which are very affordable and they do not require a power source.’
It is easier to read a digital gauge and it delivers precise and even fractional measurements. You also can read them remotely with the right equipment. Your decision will depend on your situation.
