Types of pressure gauges that are indispensible for engineering industry

Posted by Third Coast Gage & Calibration on February 1st, 2019

Those who belong to the engineering industry must be aware of the pressure gauge and its immense significance. However, if we attempt to make a quick recapitulation of the function and utility of this instrument then it can be said that a pressure gauge is an indispensible instrument when it comes to measuring the condition of liquids and gases.  

Basically, this instrument calculates this by means of presenting how much force a particular variant of liquid or gas will exert at a given environment.

There are lots more you need to know about this mighty instrument to know why it is so important tin the engineering industry.

 So, presented here is a brief overview of the different pressure gauges shared by professionals connected with companies dealing with Depth Gages For Sale and Pressure Gauge Calibration Services In Texas. Watch out!

  • Diaphragm pressure gauge

The distinctive feature of the diaphragm gauges is that it comes in the form of an elastic membrane that elongates and tends to form a capsule by joining two diaphragms together when pressure is applied.

A pressure gauge usually comprises of quite a number of such diaphragms which are formed out of the same principle. However, this is simultaneously true that more the number of diaphragms in a gauge more will be its sensitivity.

Pressure applied on a single diaphragm makes it flexible, which in turn, passes on this pressure to the pointer of the gauge through the links in the instrument that connect the different diaphragms together.

  • Bellow gauge

Bellow gauge is another variant of pressure gauge that comes with the expectation. Here the professionals at Pressure Gauge Calibration Services In Texas comment that while its fundamental structure is that of stacked diaphragms, the diaphragms of bellow gauge are made from a number of   sheets.

When pressure is applied to the diaphragms of the bellow gauge, it makes the bellow expand and become longer than what its original dimension was. Nonetheless, when the pressure is removed, the bellows shrink and get back to their original shape.  

Unlike the diaphragm gauge, in this case the pressure from the pointer is transmitted to the bellows through interconnected links.

  • Bourdon gauge

This is the third variety of pressure gauge which comes with a distinctive C-shaped tube. When pressure is applied to the tube, it deforms itself by stretching outwards. This sets the tube in motion.

The mechanism behind bourdon gauge is that it has a pointer attached to the end of the tube through interconnected links. When pressure is applied, the pointer is set into motion due to the interconnected link gear system.  

Yet another significance of this pinion gear in bourdon tube is that it the pointer is dislocated from its position when the gear is set to a circular motion due to pressure inside the tube. Eventually, this repositioning helps in identifying the pressure inside the bourdon tube.
