In the field of industrial instrumentation, reliable measurement is not a luxury, it’s a necessity. Pressure instruments, especially those operating in extreme or corrosive environments, require more than just standard protection. They need engineered solutions that perform under pressure, literally.
Diaphragm seals are used to isolate pressure instruments from process media that could clog, corrode, or otherwise interfere with their accuracy. Whether it's a high-viscosity fluid, an aggressive chemical, or a process that requires strict hygiene, diaphragm seals help maintain instrument integrity and performance.
But not all diaphragm seal assemblies are created equal. The quality of the weld, the purity and precision of the fill, and the compatibility with various instrument brands are the factors that separate our systems and processes from the rest. At Aircom, we’ve taken those factors and built a process around doing them right, in-house.
Here is how we do Diaphragm Seal Assembly the Aircom Way.
Welding is one of the most critical steps in diaphragm seal assembly. A poorly executed weld can compromise system pressure, leak fill fluid, or introduce inconsistencies in instrument readings.
That’s why every seal at Aircom is welded by our experienced technicians, in-house, using precision welding equipment. We don’t outsource this step because we don’t compromise on quality. Our welds are clean, consistent, and tested, ensuring a secure mechanical bond and long-term durability even in high-pressure or corrosive environments.
A diaphragm seal is only as good as its fill process. We apply Pascal’s Principle to ensure accurate pressure transmission between the diaphragm and the connected instrument.
Using carefully calibrated techniques, we inject the seal with high-grade fill fluid under vacuum and temperature-controlled conditions. The goal? Zero air pockets. Zero lag. Full system responsiveness.
This level of care ensures that your pressure transmitter or gauge reads consistently, no matter the conditions.
Instrumentation doesn’t live in a lab, it lives in the field. That’s why every Aircom diaphragm seal assembly undergoes pressure and calibration testing to ensure performance under realistic conditions.
We subject every unit to thermal, static, and pressure validation. If it doesn’t pass our standards, it doesn’t ship. It’s as simple as that.
Your plant may run Rosemount transmitters—or it may use a mix of brands. That’s not a problem. Aircom’s diaphragm seal assemblies can be designed to work with any brand. We’re fully equipped to pair our sealing solutions with all major instrumentation platforms.
This flexibility makes it easier for operations teams and integrators to get a custom-fit solution without vendor lock-in.
We build our seals in a clean and controlled environment designed to reduce the risk of contamination and ensure consistent assembly quality. More importantly, every member of the Aircom team brings expertise, attention to detail, and pride to their role. We don’t just build products, we build the Aircom Way.
