ABSTRACT:
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.
