A system for protecting a transducer connected thereto by damping, through a pressurized fluid, a signal to be converted by the transducer is disclosed. The system includes a transducer protector apparatus having a housing and an element for damping the signal to be converted by the transducer. The housing includes a first connector for coupling with the transducible signal source and a second connector for joining the transducer. The housing also has a fluid-containing cavity and a member for transferring to the fluid in the cavity the transducible signal received through the first connector. The damping element includes a bore defined in the housing to directly communicate the cavity with an aperture in the second connector and a pin, having a predetermined diameter less than the diameter of the bore, disposed within the bore. The transducer protector apparatus may also include a valve assembly disposed within the aperture of the second connector and may have a valve capping plug and retainer associated therewith. The system further includes a device for pressurizing the fluid contained within the transducer protector apparatus.

A system for protecting a transducer connected thereto by damping, through a pressurized fluid, a signal to be converted by the transducer, said system comprising: a transducer protector apparatus, including: a housing, including: a first connector means for connecting said housing with the transducer, said second connector means having an aperture defined therethrough; a fluid-containing cavity defined within said housing; and a transducible signal transferring means disposed within said fluid-containing cavity for receiving the transducible signal from the source and for transmitting it to the fluid in said fluid-containing cavity; and damping means for damping the signal transmitted by said transferring means, said damping means including: a bore having a predetermined diameter defined in said housing, said bore communicating said fluid-containing cavity with said aperture in said second connector means; a pin having a predetermined diameter which is less than the predetermined diameter of said bore, said pin disposed within said bore so that a space exists between said pin and the wall of said bore; and a fluid contained in said space for providing a continuous fluid path through which the transducible signal transmitted by said signal transferring means can dampingly pass around said pin to the aperture of said first connector means; and means for pressurizing the fluid in said cavity and in the space betwen said bore and said pin, said means for pressurizing the fluid including: a container having a body of the fluid contained therein; a duct having a first end thereof disposed in said body of fluid; a valve having a first end connected to a second end of said duct; a three-ended connector means having a first end connected to a second end of said valve and a second end connected to said second connector means of said housing; and a pump connected to a third end of said three-ended connector means for pumping fluid between said container and said protector apparatus so that the fluid within said protector apparatus is thereby pressurized.
