TRANSDUCER 7 kHz
Principle / Application
The Tonpilz type 7 kHz transmission transducer, is suspended at the nodal point. It is particularly adapted for the construction of hull antennas for active sonars.
It is made up of an aluminium bronze casing and a coaxial jumper cable.
On request it can be fitted with two types of mechanical interfaces, as optional suggestions.
