The Standard Open
type transducers consist of a
piezoelectric ceramic disc mounted at the
node of its fundamental resonant frequency,
a conical metal resonator bonded at the
center of disc acting as a rigid piston.
This special construction provides high
sensitivity, wider bandwidth, and excellent
durability in wide temperature and humidity
ranges and high stability in electrical and
mechanical characteristics. Due to its free
vibration character the open type
transducers are very suitable for continual
wave driving, such as Doppler motion

The Standard
Enclosed type transducers, are
designed to be hermetically sealed and can
be used for outdoor installations, as well
as dusty indoor atmospheres.
The transducers consist of a metal housing
with integral metal diaphragm. They operate
at resonance on the first harmonic overtone.
The backs of these transducers are
completely sealed with resin, protecting
them from exposure to the environment.
Although it is constructed to be watertight,
it is not recommended for use under water. |

The Pulse/Tone Burst
type transducers include two groups of
transducer: open type (PT) and
enclosed type (EP). Both of these two
type transducers are specially designed for
echo ranging systems having character of
short ringing comparing with our standard
type transducers. Several transducers of
asymmetric beam patterns were designed
specially for car reversing systems for
minimizing unwanted wave reflection picking
up from ground.
Transducers with
built-in temperature compensated capacitor
and of shorter ringing are available upon
request. |

Pro-Wave presents a series
of mechno-electrical sensors and detectors
produced by advanced piezoelectric polymer
film technology. The polymer film of
polyvinylidene fluoride (PVF2) exhibits a
conspicuous piezoelectric effect and also
has high compliance comparing with other
piezoelectric crystals or ceramic materials.
Because of its superior piezoelectric strain
constant (g value), 10-20 times larger than
piezoelectric ceramic, it is an ideal
sensing material for converting mechanical
to electrical energy.
Besides the standard products shown on this
catalogue, we are also developing a series
of sensing devices by using this particular
piezoelectric thin film material. Please
contact with us for your special needs.

斯闊企業新推出微孔噴嘴型超音波霧化換能器，此一先進之微機技術將改變超音波霧化器整體之結構。
微孔噴嘴型超音波霧化換能器由一厚度振動之壓電陶瓷片及一僅 50 μ m
厚度之金屬箔，在此一金屬箔上成形數千個約 7-10 μ m
微形噴嘴孔，利用如噴墨印表機之噴墨原理，將水或其他液體經由數十千赫芝以上之振動頻率霧化噴出。與傳統之超音波霧化器不同，液體不須預加在換能器上增加換能器工作負載；此新型換能器利用虹吸管原理將液體吸引至金屬箔下端
,
經由微孔利用高頻振動將液體霧化。因無長存液體負載，使用微孔噴嘴型超音波霧化器與傳統型超音波霧化器相較霧化效率可高數十倍以上。
除此目錄介紹之換能器外，
其他如圓型或特殊要求之換能器均可製作，請與我們聯絡 |
| 特 點 |
應 用 |
- 霧化粒徑均勻
- 霧化粒徑易於調整
- 無長存液體負載，霧化效率極高
- 無空化現象，霧化穩定
- 結構簡化小型
