50W 40kHz Horn Type Ultrasonic Cleaning Transducer for Precision Lab Hardware DIY Wash Tanks and Immersible Transducer Box Systems

GB-3540-4SH 50W 40kHz Industrial Ultrasonic Transducer

Product Overview

The GB-3540-4SH is an industrial-grade 40kHz 50W piezoelectric ultrasonic transducer engineered for precision ultrasonic cleaning equipment and immersible transducer packs. Built with high-stability PZT piezoelectric ceramics and precision-machined aluminum alloy front and rear masses, this transducer provides stable energy conversion, high acoustic amplitude, and low heat buildup under continuous industrial operation.

Key Advantages

• High Conversion Efficiency: Optimized electromechanical coupling coefficient for consistent acoustic cavitational output.
• Low Heat Generation: Minimal dielectric loss to prevent frequency drift during long operating cycles.
• Precision Ground Surface: Sanded radiating face to ensure direct acoustic coupling and durable epoxy adhesion to stainless steel tanks.
• High-Strength Mechanical Clamping: Prestressed high-tensile center bolt design to maintain mechanical integrity under intense vibration.

Technical Specifications

Component Structure & Materials

The transducer uses a Langevin sandwich structure engineered for maximum vibrational stability:

1. High-Strength Hexagon Bolt: Applies uniform pre-stress force to ensure ceramic rings operate under compression.
2. Aluminum Rear Mass: Provides matching acoustic impedance for backward wave reflection.
3. PZT Piezoelectric Ceramic Rings: High-Q piezoelectric material for sustained electromechanical conversion.
4. Copper Electrode Plates: High-conductivity terminal lugs for polarity termination.
5. Insulation Tube: High-dielectric central sleeve to prevent internal short circuits.
6. Horn-Type Aluminum Front Mass: Precision-beveled acoustic radiator that focuses ultrasound waves into the liquid medium.
7. Ground Radiating Face: Flat, sandblasted contact surface to eliminate air pockets during tank bonding.

Stud Welding & Installation Instructions

Proper mechanical mounting and epoxy bonding are essential to prevent transducer detachment, uneven cavitation, or tank cavitation erosion.

Mounting Steps:

1. Tank Surface Preparation: Clean and degrease the bottom or side wall of the stainless steel (SUS) tank.
2. Stud Welding:
   • CD Weld Stud: Fastened to the tank plate via a stud welding gun.
   • Arc Weld Threaded Stud: Attached via arc stud welding for heavy-gauge plate installations.
3. Epoxy Application: Apply high-temperature industrial epoxy resin uniformly across the radiating face.
4. Threaded Fastening: Screw the transducer onto the welded stud. Torque securely to squeeze out excess glue and eliminate air bubbles.
5. Curing: Allow full epoxy cure time before tank filling or power activation.

Note: The transducer radiating base must seat parallel and flush against the tank surface without angular tilt or central gaps.

Wiring & Electrical Connection

• Connection Mode: Multiple transducers in an ultrasonic system must be connected in parallel.
• Wire Specification: Use high-temperature stranded copper wire with a cross-section of 1.5 mm².
• Polarity Guide:
  • Connect all positive electrode lugs (center terminal plate) to the Positive (+) generator output line.
  • Connect all negative electrode lugs (outer terminal plates / housing ground) to the Negative (-) generator output line.
