Generally, a hatch cover testing device is prepared out of two units which are known to be generator and receiver. Ultrasound with emission of particular frequency of 40,000 Hz, the generator manages to prove. With the integration of magnets, it can be attached to various surfaces easily within sealed areas. Receiver is capable of receiving the signals and conversion is made which results into the indication of W/T integrity. This advance and efficient system helps the entire areas under monitoring in functioning and enhance performance may be. Moreover, with the fire extinguisher monitoring range produced by Coltraco Ultrasonic Ltd, the results can be transferred to the computer where a permanent data can be stored. It further helps to compare the results and efficiency of these devices along with the installed system you have invested on for emergency situations. Portascanner™ II is
multiple cable transit areas testing device which is efficient to direct and convert the results to audio and display. This helps to alert the responsible person to give attention more promptly then other ways.
Receiver of Portascanner™ II
It consists of extension rod connector, Gain 1,2,3, Volume Up and Down Buttons, LCD Visual Display, Mode, On and Off Buttons and Headphone Connection. Following is the way of operation of receiver:
- It is tuned for detecting the particular frequency of ultrasound ways.
- It possesses audio and visual outputs.
- As sensor rod is attached to it, a user can scan the seal at close range entirely.
- LCD screen shows the visual output of detected ultrasounds.
- The visual data received can be converted to decibels (dB) reading which is perfect to be tested to certification society standards.
- Bar graph representation is also available.
- With standard jack of 3.5 mm, a headphone is attached to the receiver to receive audio signals.
- Heterodyning is the process through which receiver converts the ultrasound waves into audio signals so that user can easily hear.
Generator of Portascanner™ II
It consists of Power On and Off Buttons, Transducers, Low Battery Indication and Battery Compartment. The operation of generator of this
cable transit watertight areas testing are mentioned below:
- It is placed on one side of the sealed compartment and turned on.
- Sensor rod is utilized to scan the seal by user standing on the other side of the compartment.
- Increased signal strength will be shown apparently for leak sites.
- The numerical display and volume of audible signals can easily show the strength of the signals received by the receiver.
