    First I'm new to this awesome forum. Second i know there are a lot of ultrasonic cleaner threads on here and i have been through some of them but it seems like none get finished. :) So I was wondering if anyone knew how to build a driver for a bolt clamped langevin for a ultrasonic cleaner. I was looking at this langevin:


    Bolt Clamped Langevin Transducer

    Part Number: SMBLTD45F40H
    Bolt-clamped Langevin type transducers (BLT) are common vibration sources in high-power ultrasonic applications such as ultrasonic cleaning tanks, ultrasonic plastic welding, ground sonar transducer, Bio Diesel mixer transducer, Solid separation transducer, stop organism growth on boat hull, Biodiesel mixing transducer, High-Torque Traveling Wave Ultrasonic Motor

    Piezo Material:
    SM118
    Body Material: Aluminum
    Dimensions: 53.75 x 45 x 35 mm
    [​IMG] Resonant frequency fr: 40 KHz±1 KHz
    Maximum Output Power : 70W, alone, or 50W for parallel connection
    Mechanical Q: 1000
    Maximum allowable velocity :40 cm/s
    Maximum allowable Temperature : 120 C
    Resonant impedance Zm:
    ≤50 Ω
    Static capacitance Cs: 4000pF ±10

    Test Condition:
    23±3 °C 40~70% R.H.
    fr, Zm, Kp => Test voltage 1Vrms
    Cs => LCR meter at 1KHz 1Vrms
    Drawings: SMBLTD45F40H,
    Applications: High-power ultrasonic applications such as ultrasonic cleaning tanks, ultrasonic plastic welding, ground sonar transducer, Bio Diesel mixer transducer, Solid separation transducer, stop organism growth on boat hull, Biodiesel mixing transducer, High-Torque Traveling Wave Ultrasonic Motor and others.
    Notes: For the thickness of the ring transducer used (5.5mm), the maximum input voltage is 1,650V but the power output should not exceed 70W for single transducer or 50W for parallel setup. If the temperature is higher than 120C the transducer will depolarize and maybe fracture. So the operating voltage suggested is between 450-500V.

    Any Help or suggestions would be awesome!

    Thank You!
