Cole-Parmer 630-0210 螺紋探頭

探針（有時(shí)也被稱為牛角）的二分之一波長的長的工具，作為機(jī)械變壓器轉(zhuǎn)換器所產(chǎn)生的振動(dòng)的振幅增加。它們包括兩個(gè)部分，每個(gè)部分具有不同的橫截面面積。在其諧振頻率驅(qū)動(dòng)時(shí)，探頭繞其中心縱向膨脹和收縮。但是，沒有發(fā)生縱向運(yùn)動(dòng)上面的螺紋結(jié)點(diǎn)（沒有活動(dòng)的區(qū)域），允許附件被連接到探頭在這一點(diǎn)上。上段和下段，更大的放大系數(shù)之間的質(zhì)量比越大。具有較小的噴嘴直徑的探頭氣蝕的產(chǎn)生更大的強(qiáng)度，但所釋放的能量被限制在更窄，更集中的字段。相反，探針尖直徑較大的生產(chǎn)強(qiáng)度較小，但能量被釋放更大的區(qū)域。前端直徑越大，體積越大，可以進(jìn)行處理，但在較低的強(qiáng)度。高增益探針產(chǎn)生更高的強(qiáng)度比標(biāo)準(zhǔn)探頭具有相同的直徑，通常推薦用于處理較大的卷或困難的應(yīng)用。探針制備高品位鈦合金Ti-6AL-4V，因?yàn)槠漭^高的拉伸強(qiáng)度，良好的聲學(xué)特性，在超聲波頻率，高耐腐蝕，低毒性，和優(yōu)良的耐氣蝕。他們可高溫高壓滅菌，螺紋連接接受更換提示，微尖的和擴(kuò)展。單獨(dú)訂購更換尖。

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, and available with threaded ends to accept replaceable tips, microtips and extenders.
