Overview For more than twenty years esa-systems has been manufacturing probes to measure any pressures relevant in aviation. Worldwide, a great number of aircraft have been equipped with esa-systems multiple probes, total energy probes and pitot tubes. Esa-systems supplies pressure probes worldwide to almost all sailplane manufacturers, several manufactures of general aviation and moreover, companies such as Diamond Aircraft and EADS are their customers. Esa-systems products are designed and manufactured in Germany.
Carbon Fiber vs. Aluminum Probes Most esa-systems probes are made of carbon fiber tubes with machined aluminum parts. The carbon fiber tubes are extremely strong and very light-weight. They also have less of a tendency to oscillate or vibrate than probes made of metal. However, most of them can be ordered with black aluminum tubes (instead of carbon fiber tubes) for the same price, but the carbon fiber versions are the most popular around the world and are the ones we stock. The black aluminum versions are special orders. I highly recommend the carbon fiber versions.
