Advanced Sensors Technology: Cutting-Edge Refinement

Micro-Measurements®, a Vishay Precision Group, Inc. (VPG) brand, has launched a series of products built using its Advanced Sensors strain gage technology.

 

Addressing the growing demand for force and strain sensors needed to manufacture precision transducers and for stress analysis test and measurements, Micro-Measurements Advanced Sensors strain gages offer a tighter resistance tolerance, improved gage-to-gage repeatability, and better stability than standard strain gages while their advanced fabrication process helps to significantly reduce lead times.

Key Advantages of Advanced Sensors Technology

As the foundation of consistently reliable and precise transducers, Micro-Measurements Advanced Sensors strain gages are built on a new manufacturing process using state-of-the-art equipment and tooling. This results in tighter tolerance products with shorter manufacturing lead times as compared to conventional manufacturing techniques.

 

Advanced Sensors Technology was shaped by decades of in-house expert knowledge, experience gained across our global portfolio of successful applications, and sustained attention to customer feedback.

 

Today customers across the world benefit from Advanced Sensors Technology in experimental stress analysis and as the sensing elements in a wide variety of transducers. This technology guarantees precise measurement of physical variables, including weight, force, torque, pressure and more.

Micro-Measurements Advanced Sensors Strain Gages Ensure:

  • tighter resistance tolerance

  • improved gage-to-gage repeatability

  • better stability than standard strain gages

  • significantly reduced lead times

 

The Micro-Measurements’ Advanced Sensors Technology product portfolio includes:

  • Linear gages

  • Shear gages

  • Circular gages

 

All gages are arranged as individual, half-bridge and full-bridge configurations-- in ranges from 350 Ω to 20 kΩ, with added flexibility in mounting options. The technology advances grid-to-grid tolerances and matching, enabling improved strain and force sensor performance.

 

In the case of full-bridge gage configurations, all intra-bridge connections are integrated directly into the pattern. This eliminates the need for traditional intra-bridge soldering. Our unique addition of gold-plated solder pads improves solder-joint reliability and reduces the risks of solder pad oxidation prior to lead wire attachment.

 

Advanced Sensors Technology safeguards close matching of grid-to-grid thermal characteristics and bridge circuit thermal output cancellation specifications--- two essential steps in accurately measuring strain.
