Cole-Parmer 630-0209 固体探头尖端

探针（有时也被称为牛角）的二分之一波长的长的工具，作为机械变压器转换器所产生的振动的振幅增加。它们包括两个部分，每个部分具有不同的横截面面积。在其谐振频率驱动时，探头绕其中心纵向膨胀和收缩。但是，没有发生纵向运动上面的螺纹结点（没有活动的区域），允许附件被连接到探头在这一点上。上段和下段，更大的放大系数之间的质量比越大。具有较小的喷嘴直径的探头气蚀的产生更大的强度，但所释放的能量被限制在更窄，更集中的字段。相反，探针尖直径较大的生产强度较小，但能量被释放更大的区域。前端直径越大，体积越大，可以进行处理，但在较低的强度。高增益探针产生更高的强度比标准探头具有相同的直径，通常推荐用于处理较大的卷或困难的应用。探针制备高品位钛合金Ti-6AL-4V，因为其较高的拉伸强度，良好的声学特性，在超声波频率，高耐腐蚀，低毒性，和优良的耐气蚀。他们可高温高压灭菌。

Probes (sometimes referred to as horns) are one-half wavelength long tools that act as mechanical transformers to increase the amplitude of vibration generated by the converter. They consist of two sections each having different cross-sectional areas. When driven at its resonant frequency, the probe expands and contracts longitudinally about its center. However, no longitudinal motion occurs at the threaded nodal point (area of no activity), allowing accessories to be connected to the probe at that point. The greater the mass ratio between the upper section and the lower section, the greater the amplification factor. Probes with smaller tip diameters produce greater intensity of cavitation, but the energy released is restricted to a narrower, more concentrated field. Conversely, probes with larger tip diameters produce less intensity, but the energy is released over a greater area. The larger the tip diameter, the larger the volume that can be processed, but at lower intensity. High gain probes produce higher intensity than standard probes of the same diameter, and are usually recommended for processing larger volumes or difficult applications. Probes are fabricated from high grade titanium alloy Ti-6Al-4V because of its high tensile strength, good acoustical properties at ultrasonic frequencies, high resistance to corrosion, low toxicity, and excellent resistance to cavitation erosion. They are autoclavable.
