25 DL Plus Ultrasonic Precision Thickness Gage with Waveform Display

 

The Panametrics-NDT™ Model 25DL PLUS ultrasonic precision thickness gage provides cost-effective solutions in applications where the opposite side of the test material is difficult or impossible to reach. An important benefit of this handheld unit is its ability to make thickness measurements on many materials in a wide variety of shapes and sizes. A large Liquid Crystal Display displays both the live ultrasound waveform and the thickness reading. Operation of this handheld gage is intuitive with a color-coded keypad and direct-access number keys. One of the many unique features of this gage, Application Auto-Recall, allows the user to select and recall any of the stored standard or custom transducer setups in the gage’s memory. This permits easy switching among our full line of contact, delay line, and immersion transducers to solve an almost infinite number of measurement problems.

INTERNAL DATALOGGER

 

The 25DL’s internal datalogger stores, recalls, and transmits 1,750 waveforms and more than 18,000 thickness readings along with alphanumeric Identificationcodes.

WAVEFORM DISPLAY

 

The A-Scan shows both the live waveform and the thickness reading, which is ideal for turbine blade inspections and any other application where the user needs to ensure proper transducer alignment.

25DL PLUS SPECIFICATIONS

 

MEASUREMENTS

 

Mode 1: Time interval between excitation pulse and first backwall echo. Using contact transducers

Mode 2: Time interval between the first interface echo after the excitation pulse and the first backwall echo. Using delay line or immersion transducers

Mode 3: Time interval between successive backwall echoes following the first interface echo after the excitation pulse. Using delay line and immersion transducers

 

Thickness Measurement Range:

Steel: 0.006 - 20" (0.15 - 500mm)

Plastic: 0.003 - 2"(0.08 - 50mm)

Thickness range depends on material, transducer, surface condition and setup selected, extended thickness ranges are possible using custom setups
