TA3540 Deflectometer

Description

The TA3540 Deflectometer is designed to interface with Thwing-Albert materials tester operating with MAP4 Materials Testing Software. The Deflectometer is designed to report extremely accurate position/deflection data for tests such as flexural bend and compression strength for materials such as rigid plastics, metal, composites, corrugated, and paperboard.

The Deflectometer is supplied with the necessary components to easily integrate with our single and dual column test frames.

• Full bridge, 350 ohm strain gaged design 
• Adjustable magnetic base for easy mounting – can be used upside down also.
• Spring-loaded arm will break free under excessive displacement
• All standard units have linearity of 0.25% of FS or better
• Includes a Shunt Calibration System 
• Rugged, dual flexure design for improved performance
