The emitters of ultrasound: characteristics of ultrasound action

Emitters (ultrasound) are used extensively in sonar. Additionally, the device used in the receivers. Modern versions are distinguished by high frequency and have good conductivity. The sensitivity of the emitter depends on many factors. It is also worth noting that the models used terminals that affect the overall level of resistance.

Diagram of the device

The Standard scheme of the device contains two terminals and a single capacitor. The rod used with a diameter of 1.2 cm Magnet to operate the system will need a neodymium type. At the bottom of any radiator you'll stand. Capacitors can be attached via an extender or terminals. Winding solenoid is used with conductivity of 4 MK.

Ring modification

The Ring of submersible ultrasonic transducers, as a rule, produced for the sounders. Most models have a dipole capacitors. Lining under them are selected from the rubber. The total resistance in devices of this type is equal to 50 Ohms. Terminals are used with and without an adapter. At the top of selenoid is a protective ring. The rod used with a minimum diameter of 2.2 cm, In some cases, capacitors are used with channel-type protection system. The conductivity in the discharge is not less than 5 MK. The frequency can vary greatly. In this case, a lot depends on the sensitivity of the element.

Device with Yar

The Ultrasonic transducer for humidifier with Yar is considered to be very common. If we consider the standard model, then it has three condenser. As a rule, they used a three-band type. The overall level of resistance in the emitters of this type is 55 Ohms. They are often raised on fish finders and low-frequency receivers. Also models suitable for converters. Magnets are used with a diameter of 4.5 cm Coasters made from brass or steel. The conductivity in the discharge is not more than 5.2 Microns.

Some modifications are used with overhead Yar. Typically, it is located above the stand. It should also be noted that there are emitters with single-pole adapters. The solenoids are only suitable for them with high conductivity. At the top of the device you are using multiple rings. The sensitivity of the discharge is approximately 10 mV. If we consider the modification for resistor capacitors, they have a common resistance level comes to a maximum of 55 Ohms.

Model with dual coil

Transducers (ultrasonic) with double winding recently manufactured amp. Such devices are widely used in converters. Some emitters are made with dual capacitors. The windings are used with a wide ribbon. The rods fit with a diameter of 1.3 cm Terminals must have a conductivity of not less than 5 MK. The frequency depends on many factors. First and foremost take into account the diameter of the rod. It should also be noted that the extenders are used with linings and without them.

The Emitters at the base of the reflector with your hands

The reflectors can be ultrasound emitter with their hands. Primarily harvested neodymium magnet. Stand applies a width of about 4.5 cm Stroke may only be installed after the rod. It should also be noted that the magnet is fixed on the lining and closes the ring.

The Terminals for the device selected conductor type. Conductivity at the discharge should be about 6 MK. The overall level of resistance in the emitters of this type is equal to 55 Ohms. Capacitors are used. Directly reflectors are selected small thickness. To set elements will have to use a blowtorch. The upper part of the rod is twisted on the film. In this case, it is important not to block the terminal.

Device for echo sounders

Emitters (ultrasound) for echo sounding devices have good conductivity. The diameter of the rod, the standard model is equal to 2.4, see Rings typically use a slinky type. Modern models are made with a conical base. They have a small weight and they can operate in high humidity conditions. Solenoids are used of different diameters. At the bottom of the device necessarily is wound tape. If necessary, the transducer for a Fishfinder can be done independently. Capacitors are employed the two-channel type. If we consider the device with the core at 2.2 cm, the total resistance level it will be 45 Ohms.

Modifications for repolocation

Emitters (ultrasonic) for repolocation are made with terminals of different conductivity. The most popular are considered to be modifications to the adapter and sensitivity at 12 mV. Some devices are equipped with a compact single-channel capacitors. Conductivity in loading is 2 MK. The magnets are established emitters of different diameter.

Most of the models are made with low stands. It should also be noted that the devicestand high frequency. The terminals have good conductivity, but in this case much depends on the thickness of the rod. In the upper part of the winding is installed protective ring. To increase the conductivity of the emitter terminal applied with a sensitivity of 15 mV.

Model low wave drag

The Ultrasonic transducer for humidifier low wave resistance stands out with compact dimensions. The windings are used with a thickness of 0.2 cm, the Magnets are mounted on stands or plates. The terminals are fixed in the upper part of the device. The standard version includes three capacitor.

The total resistance is 30 Ohms. The capacitors in some models apply two-channel type. The conductivity is about 2 MK. There are also some modifications with reinforcing bars of large diameter. They are used in sonar. Most emitters are made especially for converters. Rings are used to clamp rubber or plastic. The average diameter of the core of the modification is equal to 2.2 cm.

Device-high wave drag

Modifications of this type are made, generally for receivers. The overall level of conductivity they have is 4 MK. Most of the devices from the contact terminals. It should also be noted that there are devices with a sensitivity of 15 mV. The capacitors on the modification select the channel type. Also there is a resistor model. They have a common resistance level starts at 55 Ohms. Magnets powerful ultrasonic transducers are installed only neodymium type. The average component diameter is 4.5 cm Stand can be made with lining or insulating protective films.

Model odnopestichnyj capacitors

This type of Device is able to provide a conductivity at 5 MK. They have a fairly high sensitivity. The terminals on the ultrasonic transducer set with a diameter of 2 cm of the Winding are used only with rubber rings. At the bottom of the device applied to the dipole terminals. The overall level of resistance when the load is 5 Ohms. Capacitors may be installed to the radiators through the extenders. To extend the low frequency used by the adapter.

If necessary, you can make modifications on the two capacitors. This terminal is installed with a conductivity of from 2.2 MK. The rod is chosen with a small diameter. It should also be noted that you will need a short kickstand made of aluminum. As insulation for the terminals used duct tape. In the upper part of the radiator attaches two rings. Capacitors are mounted directly via the dipole extender. The total resistance must not exceed 35 Ohms. The sensitivity depends on the conductivity of the terminals.
