60W 28/40kHz Dual Frequency Horn Type Ultrasonic Transducer for Immersible Transducer Packs and Industrial Cleaning

GB-382840-4SH Dual-Frequency Ultrasonic Cleaner Transducer (28/40 kHz, 60W)

Product Overview & Key Advantages

The GB-382840-4SH is a dual-frequency horn-type piezoelectric transducer designed for commercial and industrial ultrasonic cleaning systems. It operates at switchable 28 kHz and 40 kHz frequencies with a rated power output of 60W, providing uniform cavitation and stable energy conversion.

• High Efficiency: Maximizes electrical-to-acoustic energy conversion.
• Large Amplitude: Delivers high mechanical vibration output.
• Low Heat Generation: Maintains low operating temperatures during continuous cycles.
• Stable Output: Delivers consistent acoustic performance.
• Cost Effective: Optimized for long service life with minimal maintenance.
• Fast Delivery: Available directly from factory stock.

Structural Design & Engineering Highlights

• Bottom Grinding Wheel Finish: The radiation base is ground flat with a fine sandwheel to ensure uniform contact and maximum adhesion to the tank plate.
• Edge Flow Horn Design: The curved profile reduces stress concentration while increasing mechanical amplitude.
• High-Grade Top Insulation: Sealed with high-temperature and corrosion-resistant insulation adhesive to prevent dielectric breakdown and ensure long-term structural integrity.

Component Breakdown

• High-Strength Hexagon Bolt: Applies calibrated pre-stress to prevent ceramic element damage under high power.
• Strong Resistance Cap: Balances vibration load distribution.
• Copper Electrode Plates: Positive and negative terminals with high electrical conductivity.
• Piezoelectric Ceramics: High-performance rings (38 × 15 × 5.0 mm).
• Frosted Radiation Surface: Sandblasted bottom face engineered for direct epoxy bonding onto stainless steel (SUS) tanks.
• Insulation Tube: Isolates the central mounting bolt from the ceramic stack.

Technical Specifications & Dimensions

Mounting Hardware Options:

• Sticker Stud: Welded to the SUS tank plate via a capacitive discharge stud welding gun.
• Backnail Stud: Welded to the SUS plate via standard arc welding.

Installation Guidelines

1. Clean, degrease, and abrade the tank mounting surface.
2. Weld the threaded mounting stud perpendicular to the stainless steel plate.
3. Apply epoxy adhesive evenly to the frosted base of the transducer.
4. Thread the transducer onto the stud and tighten to specified torque.
5. Ensure the base makes flush, 100% surface contact with the plate. The stud must not be tilted, and no gaps or deformation should exist between the base and tank surface.

Wiring & Electrical Connection

• Cable Specification: Use wire with a cross-section of 1.5 mm².
• Connection Mode: Transducers must be wired in parallel.
• Polarity Instructions: Connect the positive (+) line from the generator to all positive electrode tabs, and the negative (-) line to all negative ground tabs.

Applications

Suitable for standard and customized ultrasonic cleaning setups:

• Ultrasonic Immersible Transducer Packs: Submersible boxes and immersible tube arrays for retrofit into existing tanks.
• Ultrasonic Cleaning Machines: Benchtop units, industrial degreasing baths, and multi-stage automated cleaning lines.
