Pressure gauges are important devices used in many applications. Some of the common applications of a sophisticated pressure gauge are to measure liquid or gas pressure in many industries such as the chemical, beverages, oil and gas, medical, power and other industries. In addition, there are simple pressure gauges such as tire pressure gauges and fuel pressure gauges generally used for normal applications in homes and small commercial shops.

Pressure gauges minimize accidents in an industrial environment and save costs by preventing production downtime. Pressure gauges come in different types based on their ability to measure a particular range of pressures. These are positive pressure gauges, vacuum pressure gauges, compound pressure gauges and differential pressure gauges. You can select one of these pressure gauges depending on your requirements.

Before selecting a pressure gauge, you must know the following things:

1. Range of pressure you want to measure
2. Environmental considerations such as temperature, humidity and other conditions which can affect the performance of your pressure gauge
3. Level of accuracy required

Figure out important parameters related to pressure gauges

The first step in selecting a pressure gauge is to understand its different technical properties. Some of the important parameters to know before selecting a pressure gauge are process media, pressure range, material, environment and mounting requirements.

I recommend: Transcat, one of the most reputed pressure gauge manufacturers, explains various technical parameters and guidelines for a pressure gauge. Airedale Instruments also provides guidelines for choosing the correct pressure gauge.

Buy pressure gauges from reputable manufacturers

Once you have identified your requirements, look around before you buy; pressure gauge manufacturers have many models available in the market. Select pressure gauge manufacturers that have a good range of products.

I recommend: Honeywell is one of the most reputable manufacturers of digital pressure gauges, offering diverse gauges such as water pressure gauges, oil pressure gauges and air pressure gauges. Ashcroft also offers wide varieties of pressure gauges available with a broad range of dial sizes, accuracies, pressure ranges, materials and other features.

Consider leasing pressure gauges to save cost

If you require a pressure gauge for short-term duration or have budgetary constraints, renting rather than purchasing may be a better option.

I recommend: GE Sensing & Inspection Technologies offers a rental program to meet your short-term requirements for various types of pressure gauges. You can also rent pressure gauges with various pressure ranges through SEMCO Maritime, which caters to the marine and energy sectors.
