Cygnus Instruments Ltd
Ultrasonic Hatch Cover Testing
Cygnus Instruments also manufacture an ABS type approved ultrasonic hatch cover leak detector, Cygnus Hatch Sure, which is used to evaluate cargo hold hatch covers and door seals to determine water leaks and weather tightness.
The hatch sure transmitter is a powerful, battery operated, ultrasound transmitter with 19 x 40 KHz elements. The transmitter can be placed in the bulk carrier hold where it will the fill the hold with ultrasound and any ultrasound that escapes, through gaps in damaged areas of the hatch cover seals, can then be detected by the hatch sure receiver.
The transmitter has six selectable pre-set power levels to give variable output allowing the unit to be used in confined spaces, such as testing watertight doors.
The hatch sure receiver is used to display the sound energy level from the hatch sure transmitter, that passes through any gaps in the bulk carrier hold or cargo hold, which enables the user to quickly and accurately locate any leaks from the bulk carrier hold, cargo hold hatch covers or even door seals.
