| Lewis transducers are not crystals. They are magnetostrictive nickel alloy units permanently silver-brazed to a heavy 316L stainless steel piate diaphragm. Lewis transducers are guaranteed for ten years not to fail or degrade. In fact, not one has ever failed. Lewis transducers are designed for heavy-duty continuous performance. They withstand abuse and high temperature operation. built to deliver years of proven service. Lewis immersible transducers can be installed in opposing configurations for high intensity cleaning applications. For difficult cleaning situations, Lewis offers the ultimate in high-density cleaning with opposed transducer systems operating at differing frequencies (i.e., 16kHz and 20kHz). |
