Title:
MANUFACTURE OF SIGNAL CONDITIONING PLATE AND METHOD FOR ADJUSTING STANDOFF DISTANCE THERETHROUGH
Document Type and Number:
WIPO Patent Application WO/2015/111938
Kind Code:
A1
Abstract:
The present invention provides a manufacture of a signal conditioning plate and method for adjusting a standoff distance therethrough, the method comprising the steps of: providing fixing casing in a fixing part, and inserting and fixing an underwater hydrophone into/to the fixing casing; forming, in a vertical moving part, a hydrophone hole through which the underwater hydrophone can pass, and positioning the vertical moving part at the upper part of the fixing part such that the vertical moving part is spaced from the fixing part at a predetermined distance; providing a height adjusting part between the fixing part and the vertical moving part so as to structurally connect the fixing part and the vertical moving part; and vertically moving the vertical moving part through an expanding or contracting action of the height adjusting part so as to adjust a distance between the fixing part and the vertical moving part, such that a standoff distance between the underwater hydrophone and the vertical moving part is adjusted. According to the present invention, it is possible to avoid an area where measurement of an underwater hydrophone is impossible by suitably adjusting a standoff distance according to a frequency band of noise to be measured when underwater noise is measured, and also, to firmly fix the underwater hydrophone to a signal conditioning plate such that the fixed state is not released even though the underwater hydrophone is exposed to an underwater environment and an external force is applied to the underwater hydrophone. Thus, problems such as the impossibility of utilizing signals due to an area where measurement is impossible which occurs in a specific frequency band when underwater noise is measured, or the deterioration of the reliability of the measurement result, do not occur.
