Under Construction !!

The page, that is - the penetrometer was built in 1994 and is now on its way to Titan!

The penetrometer is mounted on the bottom of the Huygens probe descent module and will record the impact with the surface. It comprises a disk of PZT-5A piezoelectric ceramic hel under preload between two Vespel washers with a hemispheric-tipped titanium bolt. When the head is pressed, the ceramic generates a charge which is recorded by an amplifier and telemetered back to Earth
