8 channel ultrasonic multiplexer
The Mantis â€œModel 800â€ 8 channel multiplexer is designed to provide eight separate ultrasonic pulserreceiver transducer channels to a single ultrasonic flaw detector. These channels are activated in sequence using the transmitter output of the flaw detector to trigger the multiplexer channels thus requiring one pulsedisplay time frame for each channel. The Mantis model 800 includes the â€œMAX Channelâ€ selector switch which allows the multiplexer to apply the entire pulse rate supplied by the flaw detector to only those channels used. If only one channel is selected, then 100 percent of the pulse rate is applied to that channel.
This model also includes the â€œFlaw Gate Inâ€ feature. This feature allows the LEDs on the front panel to illuminate green when each channel is activated but if the flaw detector gate responds to an indication within the gate, the LED for that specific channel will illuminate red. This feature allows the operator to identify the transducers that receive a return indication that exceeds the flaw gate.
Individual channels can also be selected using the sequence toggle switch sequence push button feature. This feature allows the operator to sequence between pulserreceiver channels and display only the channel desired. Displaying only one channel provides for an easy gain and damping adjustment for a specific transducer.
