25MX Plus, Multipoint & Single Precision Thickness Measurement Gage

 

The Panametrics- NDT™ 25MX PLUS is an ultrasonic precision thickness gage that provides cost-effective solutions in applications where the opposite side of the test material is difficult or impossible to reach. Multipoint and single thickness measurements can be made on a wide variety of materials including metal, plastic, rubber, glass, fiberglass, and composites.

Multipoint Thickness Measurements

 

Connected to the optional MX-8 multiplexer, the 25MX PLUS has the ability to collect and display thickness measurements from up to 8 separate transducers.

 

Special software on the 25MX PLUS allows the user to select:

 

• Number of channels (1-8)

• Max Mode

-Off

-Single Channel (manual switching)

-Single Sequence (switch through selected channels on command)

-Sequence (continuous channel switching)

• Channel Rate (1, 2, 4, 8, 16 or 20 Hz; thickness output and channel number)

 

Single Thickness Measurements

 

The 25MX PLUS operates as a ‘standard’ precision thickness gage when not connected to the MX-8 Multiplexer.

 

FEATURES

 

• Single or multipoint thickness measurements

• Connects up to 8 transducers

• User selectable: number of channels, channel sequencing, and channel rate

• Uses contact, delay line, and immersion transducers
