A device that is used for measuring the pressure in a gas or liquid is known as a pressure gauge. These pressure gauges are commonly used in every part of the globe in factories and industries since they come at an affordable price.

These are pressure sensors that are used readily in industrial equipment. Since these are installed on a huge number, their maintenance becomes quite hard. Because of this reason, it’s not an uncommon scenario to find a lot of gauges that don’t work properly.

This can turn out into a bad situation due to having a failed pressure gauge, the safety of these instruments might be compromised, which is why it’s important to have the right one like WIKA pressure gauge. If you have the right pressure gauge, installing only a few instead of a lot of them is a better option for safety and accuracy as well.

Let’s have a look on the steps to choose the right pressure gauge:


If you are using a mechanical gauge then you can measure the accuracy by full-scale range calculated in percentage. The best mechanical gauges are manufactured by WIKA that are reliable and long-lasting for any industrial purpose.


There are multiple sizes of pressure gauge dials that have a diameter that ranges from 11⁄2˝ to 16˝. For the most part, intelligibility necessities, space constraints and required gauge precision decide dial size. For 0.25 to 0.5% accuracy, the requirement of dial sizes are generally large. 


Natural contemplations incorporate surrounding temperature, air-borne particulate, buildup, dampness, water and synthetic substances, all of which can influence gauge execution. 

Encompassing temperature may influence the precision and trustworthiness of the gauge. Encompassing conditions may necessitate that the gauge is segregated from temperature boundaries. At the point when required, the gauge ought to be detached from temperature limits with an adaptable line gathering. 

At the point when surrounding conditions are destructive, contain an enormous number of particulate or if the gauge will be presented to a wet or moist condition like mugginess, wash-downs or downpour, determine a gauge that is weatherproof/hermetically fixed or fluid filled. 


The wetted pieces that are present in the pressure gauge, the cylindrical tube and its attachment must be compatible with procedure media in order for it to work properly. If not perfect with the wetted pieces of the gauge, consumption will happen. Erosion of gauge wetted parts will, in the end, cause gauge disappointment and perhaps wellbeing issues. At the point when the gauge wetted parts are not good with the procedure media, a stomach ought to be considered. 

5. Size Of The Connection

Gauges are accessible with an assortment of different connections that includes NPT, DIN, JIS, BSP and SAE. Procedure pressure gauges with 41⁄2˝ dial sizes or bigger are frequently provided with a 1⁄2˝ NPT connection that will support the gauge the best way. 

Elements to think about when choosing a pressure gauge association to incorporate procedure pressures, gauge estimate and weight, space impediments, spill uprightness, and past experience.

6. Range of Pressure

ASME B40.100 prescribes that typical working pressure be kept to 25%-75% of the scale. On the off chance that throb is available simultaneously, greatest working gauge pressure ought not to surpass half of the full-scale run.  

To find the right pressure gauge,  consider the process of the gauge, how much range it provides you, in what environment it needs to be used, proper accuracy of the gauge, the dial size and the requirements for mounting of the gauge.
