Pressure indicators

Are you tired of constantly dealing with damaged components and unexpected system failures due to clogged filters? Introducing our cutting-edge differential pressure indicator solutions, designed to optimize your filtration systems and protect your critical equipment.

By incorporating our advanced differential indicators into your filtration process, you can minimize maintenance, improve efficiency, and ensure the longevity of your pumps, valves, and other vital components. Fluid Conditioning Products is a leader in providing advanced differential pressure indicator solutions for the global aerospace industry and beyond. For more than 60 years, FCP has designed and developed indicators used in hydraulic, lubrication, fuel, and pneumatic systems for all types of commercial and military aircraft

But that’s not all. Our indicators can also be found at sea and on land in aircraft carriers, submarines, destroyer ships, and tanks. Don’t let poor filtration hold you back. Please request a quote today and experience the difference our differential pressure indicators can make in your systems.

Advantages of Systems Using Pressure Indicators

Differential pressure indicators offer numerous benefits to your filtration systems. With reduced maintenance requirements, improved efficiency, and enhanced equipment protection, DPIs are essential to your operations. By measuring the difference in pressure between the inlet and outlet sides of your filter, you can easily detect when it’s time for a filter change or cleaning.

Reduce Maintenance

FCP indicators use a pop-up button that signals when a filter is clogged. More complex indicators may have an electrical switch that illuminates a light or triggers another response. These triggers let operators know when it’s time to clean or replace an oil filter rather than rely on scheduled maintenance or visual inspections that are time-consuming and labor-intensive.

Improve Efficiency

DP indicators play a crucial role in the efficiency of your machine’s filters. Because we equip our filtration systems with the appropriate type of indicator to meet customer engineering specifications, you can rest assured that your plane, ship, or fighter jet’s filtration is working at its best because operators will know when they need to be cleaned or replaced.

Protect Equipment

DPIs provide essential protection for your equipment by detecting clogged filters before they cause damage to critical components in your system. When filters become clogged, the pressure difference increases, leading to a higher risk of equipment failure due to excessive strain on pumps, valves, and other essential components.

Pressure Indicators Industry Applications


Differential indicators are vital for various industries, including manufacturing, aerospace, hydraulic systems, and process engineering. By incorporating DPIs into their filtration processes, these industries can optimize performance and protect their essential equipment. FCP manufactures mechanical indicators, including thermal lockout and anti-reset mechanisms.

FCP has also developed an indicator sensitive to thermal lockout. These devices are used in differential pressure indicators to prevent false activation below a predetermined temperature. The objective is to avoid unwanted indications during high fluid viscosity periods, such as when starting aircraft.

Hydraulic Systems


Although hydraulic oil won’t freeze at extremely low temperatures, it doesn’t move well when it’s cold. Our sensitive indicators are also used in hydraulic systems during cold weather to prevent thermal lockout and deregulation of the system’s fluids.


Other Applications


We continue to develop innovative ways to use indicators and ensure our filter units’ proper functioning and safety. Examples include indicators for low differential pressures, high pressures, or extreme temperatures.
