60W 120kHz Precision Ultrasonic Cleaning Transducer Straight Column Sensor for Immersible Packs and Degreasing Tanks

GB-38120-4AH 120kHz 60W Industrial Ultrasonic Cleaning Transducer

Product Overview & Key Advantages

The GB-38120-4AH is a high-frequency (120kHz), straight-column piezoelectric transducer engineered for precision ultrasonic cleaning applications. Manufactured directly from industrial-grade aluminum alloy and high-stability piezoceramics, it delivers uniform acoustic cavitation with minimal thermal loss.

• High Conversion Efficiency: Optimizes electrical-to-acoustic energy transfer.
• Large Amplitude & Stable Output: Maintains consistent vibration intensity during continuous operation.
• Low Heat Generation: Extends continuous run time and protects internal piezoceramics from thermal degradation.
• Cost-Effective & Direct Factory Supply: Ensures industrial-level consistency and prompt delivery.

Structural & Engineering Innovations

• Fine Ground Base Surface: The bottom radiation face is ground with a fine sandwheel to enhance resin bonding adhesion to stainless steel tanks.
• Edge Flow Acoustic Horn: The smooth profile reduces energy concentration stress, increasing structural integrity and amplitude efficiency.
• New Top Insulation Design: Sealed with high-temperature, corrosion-resistant insulating adhesive to prevent electrical arcing and moisture intrusion.

Technical Specifications

Mounting Stud Options

• Sticker Stud: Welded to the stainless steel (SUS) plate using a dedicated stud welding gun.
• Backnail Stud: Welded to the SUS plate via manual arc welding.

Component Breakdown & Construction

Every GB-38120-4AH transducer is assembled using precision-machined components:

• Strong Resistance Back Cap: Provides uniform pre-stress distribution across the ceramic stack.
• Pure Copper Electrode Plates: Ensure optimal conductivity and low contact resistance.
• Central Insulation Tube: Prevents short circuits between the high-strength center bolt and the piezoceramics.
• High-Performance Piezoceramics: Industrial PZT rings designed for low dielectric loss at 120kHz.
• Frosted Radiation Surface: Textured base promotes epoxy mechanical interlocking.
• High-Strength Hexagon Bolt: Locks the assembly with precise torque to maintain stable resonant characteristics.

Tank Installation & Stud Alignment Guide

Step-by-Step Installation Procedure

1. Surface Preparation: Clean and degrease the bonding area on the stainless steel tank bottom.
2. Stud Welding: Weld the threaded studs strictly perpendicular to the tank surface.
3. Glue Application: Apply high-strength epoxy adhesive evenly across the frosted bottom of the transducer.
4. Mounting & Tightening: Thread the transducer onto the stud and tighten with a hex wrench to squeeze out air bubbles and form an even glue fillet.
5. Curing: Allow the epoxy to cure fully at the recommended temperature before wiring or liquid testing.

Crucial Installation Rules:

• Stud Perpendicularity: Studs must not be tilted. A tilted stud prevents flush contact and causes energy loss.
• Tank Flatness: Transducer radiation surfaces must seat completely flat against the tank with no gaps, intervals, or sheet deformation.

Wiring Instructions & Polarity Connection

• Wire Specification: Use 1.5 mm² multi-strand high-temperature copper wire.
• Connection Mode: Multiple transducers must be connected strictly in parallel.
• Polarity Connection:
  • Connect the generator Positive (+) output line to the positive electrode lugs (middle tab between ceramics).
  • Connect the generator Negative (-) output line to the negative electrode lugs (outer tabs / housing).
