Elcometer 204, 304 & 307 Transducers

The Elcometer range of dual element transducers is designed to ultrasonically measure material thickness when access is only available to one side of the material under inspection.

Transducer List

 

Dual element material thickness transducers are ideal for inspecting metal substrates but can also measure thicknesses of other materials, such as plastic, composites or fibreglass.

 

Dual Element Transducer A dual element transducer consists of two crystal elements housed in the same casing, separated by an acoustic barrier. One crystal transmits sound energy whilst the other crystal receives any reflected sound energy.
   
  A single element transducer consists of single crystal element housed in casing. The single crystal both transmits and receives the sound energy. It is common for a Single Element Transducer to be supplied with a delay-line to enable precision measurements on thinner materials.

 

Frequency and Diameter Disks

Transducers can be selected by frequency and the size of crystal. Frequency of a transducer is determined by the type of material and expected thickness range. The choice of the crystal size is determined by the access, shape and surface finish of the object to be measured. Each ultrasonic transducer can be easily identified by the disk on the top.

 

 

 

 

 

 

 

 

Dual Element Transducer Characteristics Explained

Dual Element Transducers denoted as HD/CT (Highly Damped Transducer/ Damped Coating Thickness Transducer) are necessary when using the Echo-Echo ThruPaint™ (E-E) measurement mode. Additionally CT (Damped Coating Thickness Transducer) enables simultaneous coating thickness and material thickness measurement on selected gauge models.

Special transducers are available for taking thickness measurements on high temperature surfaces.

 

 

Super Standard
High power transducer for increased range and penetration through sound absorbing materials.

 

High Damped
Limiting the duration or decreasing the amplitude of vibrations. For use with EE (ThruPaint™) only.

 

Composite
High gain transducer for increased power and penetration. 

 

High Resolution
Features increased near surface resolution, ideal for use on thin substrates.

 

Coating Thickness
Utilising ThruPaint™ technology these transducers are capable of simultaneous measurement of coating and material thickness.

Technical Specification

 

Intelligent Dual Element Transducers

 

When selecting a transducer it is important to choose one which will meet the specific application’s needs. The type of material to be tested, the measurement range, the shape of the substrate (curved or flat) and the size of the material should be considered when selecting the appropriate transducer. All part numbers starting with ‘TXC’ are Potted Right Angle transducers and are supplied with a calibration certificate.

 

The Elcometer Transducer range has intelligent automatic transducer recognition ensuring correct probe identification even when the transducer is changed.
