41S30 20Khz Ultrasound Replacement Dukane Converter with Air
Cooling Hole
Description:
Ultrasonic transducer is an energy conversion device that converts
the input electrical power into mechanical power. It is the heart
of the ultrasonic welding machine. Only with a suitable ultrasonic
transducer can the ultrasonic welding machine be better used.
This 20 KHz Ultrasonic Dukane 41S30 Converter uses the same piezo driver assembly as 110-3122 standard heavy
duty transducer but has a sealed housing and a 24" cord terminating
in a mil-spec connector to facilitate use in harsh environments or
where the equipment must be hosed down for cleaning. The housing has fittings for 1/4" OD poly tubing
to carry dry cooling air to and from the driver assembly. Can not
be mounted in a standard Dukane press. Requires the use of
200-1233-10 ultrasound cable. Output thread is 1/2-20.

How to Choose the right transducer?
The choice of ultrasonic transducer should pay attention to the
matching of input and output, mechanical installation and matching
size, and the following parameters should be considered:
1. Resonant frequency:
The frequency refers to the frequency measured by the transmission
line method with a frequency generator, millivoltmeter, or the
frequency measured with an impedance characteristic analyzer or
similar instruments. Generally known as small signal frequency. The
opposite of it is the machine frequency, that is, the actual
operating frequency measured when the customer connects the
transducer to the drive power supply through a cable and is
energized with no load or load. Because the matching circuits of
customers are different, the frequency of the same transducer with
different driving power supply is different, and such frequency
cannot be used as the basis for ordering.
2. Transducer capacity:
That is, the free capacitance of the transducer can generally be
measured with a capacitance bridge at a frequency of 400Hz-1000Hz,
or an impedance characteristic analyzer similar to the instrument.
The capacitance of the ultrasonic transducer can also be measured
with a general portable capacitance meter.
3. Way of working:
Due to different processing methods and requirements, the working
methods of ultrasonic transducers can be roughly divided into
continuous working (metal welding) and pulsed working (plastic
welding). Different working methods have different requirements for
the transducer. Generally speaking, continuous work has almost no
pause time, but the working current is not very large, and the
pulse work is intermittent, with pauses, but the instantaneous
current is very large, and the power in both states is very large.
Ultrasonic transducer type and maximum power:
There are different requirements for the nominal power of machines
for different purposes, and the nominal power of the same
ultrasonic transducer may be different when used on different
machines. To avoid ambiguity, customers should specify the
structure of the transducer, such as column type, inverted horn
type, etc., as well as the diameter and number of piezoelectric
ceramic wafers.
