  • Page 41: Parts Of An Echosounder

    EQ42/50/52 Principles of operation Chapter 8 8.1 Parts of an echosounder An echosounder is composed of a display screen, processor, and receiver/ transmitter unit which in the case of the EQXX, are housed in one unit. Connected to this unit by a shielded cable is the transducer which is mounted horizontally on the bottom of the hull or on the transom.

  • Page 43: Transducer Beamwidth

    EQ42/50/52 Principles of operation Chapter 8 8.2.1 Transducer beamwidth The transducer mounted to the hull of your vessel serves as both a “speaker” when transmitting, and as a “microphone” when the echosounder is receiving. Similar to the way a flashlight focuses light, most of the sound from your transducer is focused downwards with a smaller amount going out to the sides.
  • Page 44: Effects Of The Vessel's Speed

    EQ42/50/52 Principles of operation Chapter 8 The center of the sound beam is the most intense, then as you move out towards the sides of the sound beam there is a point where the intensity of the sound is half what it was in the center. The distance moved is the “beamwidth”.

The EQXX allows you to set the alarm depths and to enable or disable both the minimum and maximum depth alarms.

  • Page 71 EQ42/50/52 Glossary of terms Appendix A Ping to ping filter – can be set to either on or off. With the filter “off”, then each received echo will be reflected on the screen. Whereas with the filter “ON”, the system will compare every two echoes received and only reflect on the screen what is received from both echoes, which will give a more uncluttered and precise presentation.
  • Page 72 EQ42/50/52 Glossary of terms Appendix A Transducer – the transducer serves as the acoustic “loudspeaker” and “microphone” to send and receive the signals through the water. Transducers are most often made from ceramic elements carefully built into a robust housing. The ceramic elements change shape when a voltage is placed across them (when the EQXX transmits a signal), and they also generate a voltage when they encounter sound waves (as when the EQXX receives an echo).
