Factors to Consider When Buying Vacuum Gauge

Tech

Various types of pressure gauge and sensors are available out there and you can pick anyone according to your requirements. Choosing the right pressure gauge can be a daunting task if you do not have any prior experience and knowledge. Vacuum gauges are used to measure the density, pressure,and level of liquids, gas, vapors, etc.

With so many brands and types available in the market, choosing the best vacuum gauge can be a confusing task. You can, however, make the task easy with few simple steps. In this article, we will highlight the key factors you need to consider when buying vacuum gauges. Hence, go through the article and shop like a pro. 

Pressure Ranges 

Pressure range or operating range is one of the most important factors to look for. You need to evaluate your purpose or working principles before choosing the pressure range. If you are looking for low vacuum ranges, active strain gauges, bourdon tubes, bellows and capacitance sensors can be the best options.

If you are looking for a mid-range vacuum, you can go with capacitance sensors, Pirani type gauges thermocouple, etc. For high-pressure ranges, you can pick Bayard-Alpert hot cathode or cold cathode gauges can be the best choices. 

Direct or Indirect 

When shopping around, you will come across two types of vacuum gauges – direct vacuum gauge and indirect. The categories are divided according to their functionality. It often depends on the way these gauges are used – either gauges are used directly to measure pressure by impinging the molecules available in gas or they measure pressure indirectly by using properties available in gasses.

The measurement of gas property can vary with pressure. Here, you must remember one thing that indirect gauges act according to the level of gas. Direct gauges, on the other hand, are used for low vacuum range, while indirect vacuum gauges are used for middle and high vacuum ranges. 

Types of Gauges 

Different types of pressure gauges are available out there and you have to be careful while choosing the one. As a user, you must pick the right type of gauge so that you can implement it for the right job. If you are planning to measure atmospheric pressure, choose gauge pressure.

Compound pressure is another common variant of the vacuum gauge pressure tool and like the gauge pressure, it is also vented into the atmosphere. 

Likewise, if you want a pressure gauge that is not vented to the atmosphere, you can go for the sealed pressure gauge. Absolute pressure works differently. It is not vented and it comes with a sealed chamber under a complete vacuum.

Control 

Some users often want to check the indicated vacuum pressure manually, while others prefer turnkey systems that feature interlocks. You can find many variations of advanced gauges. Relay control is one of the most popular features customers prefer when buying the best vacuum gauge.

The relay control becomes active at a certain vacuum level. Such pressure measuring equipment offer analogue output that interfaces with a PCL or other advanced system to control or regulate the entire system.

The Cost 

Cost is certainly an important factor that you need to be careful about especially when you come with a tight budget. If you want to buy the best vacuum gauge, you certainly have to pay a good amount for a quality product. Hence, plan your budget and consider the cost of the tool before you make any decision. Cheap options will always be there but you must not compromise with the quality just to save on a few bucks.

These are some of the key factors you need to look at when buying the best vacuum gaugeIf you are a first-time buyer, you can also talk to an expert or browse across the best vacuum gauges online to make an informed choice without any hassle.
