Abstract

As a conventional antifouling measure to prevent adherence of aquatic organisms to a submersible sensor unit, a grease containing a stimulant, such as mustard, capable of repelling aquatic organisms is applied onto a sensing part thereof, thereby preventing adherence of the aquatic organisms. However, the irritant-containing grease applied onto the sensing part will come off within one to two months, resulting in disappearance of its effect. Thus, it is necessary to perform work of pulling up the submersible sensor unit and re-applying the grease, in each case. The present invention provides a water flow resistant submersible sensor unit which comprises an aquatic organism adherence preventive film capable of preventing adherence of aquatic organisms even when used in the submersible sensor unit for about half a year, almost without involving any underwater movement, and capable of, after use, being easily peeled off from the submersible sensor unit.
