A manometer is an analog or digital gauge used to measure the pressure of a fluid.
The operation of the manometer is carried out through a Bourdon tube, when it receives pressure it extends and transmits a movement to a needle that is described in a sphere previously regulated to an established pressure scale.
They are used in any type of industry where it is required to know the pressure being worked on. Mining, food, steel, petrochemical, energy, automotive, domestic.....
Industrial analogue pressure gauges are basically built with a stainless steel casing and you can select either a brass or stainless steel fitting. They can have a glycerin bath inside, which allows a better definition of the reading.
The scale can vary from 0 to 1000 bar, (see other scales)
