Differential pressure (DP/∆P) is the difference in pressure between two points in a system. For example, if the liquid in one pipe flows at 100 psi and in another pipe flows at 50 psi, the differential pressure would be 50 psi. Read our blog to learn more.

Positive Pressure – A pressure greater than atmospheric or barometric pressure using ambient pressure as the reference.

Vacuum Pressure – A negative pressure less than atmospheric or barometric pressure using ambient pressure as the reference. Read our blog to learn more.

Compound Pressure – Measures both positive and negative (vacuum) pressures. Read our blog to learn more.

Open front case means there is no partition or barrier between pressure element and window. These cases are less expensive and most often used in commercial applications. Read our blog to learn more.

Solid-front case means there is a partition with minimal openings between the pressure element and window. These cases are typically more expensive but have an added safety feature. This is important for use in high-pressure applications in process plants, for example, that have the possibility of rupturing. Read our blog to learn more.

The first step in selecting a pressure gauge range is to understand the operating pressures of your process.
Ashcroft follows ASME B40.100 or EN-837-1 standards, which recommend the following:

• Operating pressure should be 25% to 75% of scale, and the gauge range should be twice the operating pressure.
• Ideally, the mid-scale on your dial should be around 12 o’clock, or the mid-scale of the full-scale gauge span.
• If pulsation is present, the maximum operating gauge pressure should not exceed 50% of the full-scale range.

If you want to avoid instrument problems stemming from corrosion, you should ensure the material for the instrument’s wetted parts is suitable for the process material’s composition, concentration and temperature. If it is not possible to choose a compatible wetted material, you can integrate a diaphragm seal/instrument isolator or isolation ring constructed from an appropriate material for the process.

Most gauges can be attached to a diaphram seal. If you don’t see the wetted material you need or if multiple wetted materials can be used for your application, select “not sure.”
