The Portascanner® Watertight is a watertight integrity testing device. It has two main components – a generator and receiver. The ultrasound generator emits a specific frequency of ultrasound (40,000 Hz). It is magnetic so can be attached onto a wide range of surfaces within sealed areas. The receiver then picks up the signal and converts it into a result indicating W/T integrity.
We have mentioned the details of two main functioning unit of this ultrasonic hatch cover tester below:
Generator – Portascanner® Watertight
The generator is an ultrasonic generator with three transducers. This will produce a strong signal in one direction i.e. directly from the transducer, which fills the compartment being tested with ultrasound pulses e.g. providing sufficient coverage to fill the hold when the hatch-covers are closed. The generator is permanently fitted with a powerful magnet which allows it to be attached to the vessel’s structure where required. A magnet cover is provided when the magnet is not in use
Receiver – Portascanner® Watertight
The receiver uses ultrasonic technology to convert the 40KHz pulses sent by the generator into three easily comprehensible readings: audible, bar graph and numerical which enables the operator to understand if the seal is wholly watertight or to what extent a leak exists.
