Reliable Pressure Switches: A Critical Component for Hazardous Areas

Reliable Pressure Switches: A Critical Component for Hazardous Areas

In no application is pressure switch reliability more critical than when dealing with explosive atmospheres, flammable material, or other hazardous locations. Because of our quality standards and wide range of hazardous certifications, Custom Control Sensors has prided itself as being the industry standard for Class I Div. 1, 2 safety monitoring and protection.

Hazardous Applications where CCS products are found:


Recent Advances in Commercial Aviation Safety: Pilotless Planes

Recent Advances in Commercial Aviation Safety: Pilotless Planes

Technology in the Cockpit

We've all heard of the push to develop driverless car technology so it makes sense that the most recent advance in commercial aviation safety is the pilotless plane.

One such aircraft was tested this month in New York. Thom Patterson of CNN wrote that the experimental plane known as Centaur, "flew with no pilot in the cockpit, becoming the first large-scale fixed wing unmanned aircraft to fly at an FAA-approved test site, according to Aurora Flight Sciences Corp.,

The Importance of Good Fuel and Oil Management on Aerospace Engines

The Importance of Good Fuel and Oil Management on Aerospace Engines

Fuel and Oil Management Essential to Aviation Safety

Aircraft safety issues arise from three fuel-related conditions: fuel starvation, which means the fuel fails to reach the engine, complete fuel exhaustion before landing, or contamination and dirty fuel and oil which clogs filters and leads to increased maintenance costs or worse engine shut down. Therefore, fuel and oil management on aerospace engines is an essential component to safety and reliability.

O-Ring Matrices

CCS has created a few matrices that can be useful in determining the correct o-ring seal for a given pressure switch application. The o-ring seal is important in that it seals the pressure port to the rest of the pressure switch and prevents any leakage of the medium being sensed.

This picture shows a cutaway portion of the pressure port for a 604 series pressure switch. You can see the o-ring seal sits right below the polyimide diaphragm for the 604 series. The o-ring and the diaphragm both make direct contact with the medium so so it is very important that they are both chemically compatible with that medium otherwise the seal could fail.
