ICP® Beschleunigungssensoren mit hoher Empfindlichkeit

für niedrige Frequenzen und seismische Anwendungen

Diese Sensoren wurden speziell für Anwendungen entwickelt, wo es nötig ist, sehr kleine Schwingungen zu erkennen, wie sie bei großen Strukturen, Fundamenten, Gebäuden und Erdstößen vorkommen. Für diese Sensoren typisch sind die aussergewöhnliche Auflösung verbunden mit einem besseren Ausgangssignal und weniger Rauschen. Alle Sensoren sind hermetisch in einem Titanium- oder rostfreiem Stahl-Gehäuse versiegelt.

Die Modelle mit 2-Pol Militär-Stecker sind zusätzlich elektrisch isoliert und hervorragend gegen hochfrequente und elektromagnetische Störungen geschützt.
