Strain Gage Sensors Offer Improved Humidity Protection

The Micro-Measurements brand of Vishay Precision Group, Inc.  introduced the CHA Series – humidity resistant strain gage sensors. Micro Measurements is a worldwide industry leader in the field of stress analysis using resistive-foil sensors for high-precision strain, high-stress and force mechanism measurements.
 

The new CHA Series humidity resistant strain gages are the latest addition to the company’s CEA Series strain gages, which are among the most popular of Micro-Measurements’s offering of strain gages.  The CHA Series offers better humidity performance compared with the CEA family, making it the ideal choice for the most demanding applications such as humidity conditioned composite materials. Built to improve perfromance under ASTM-5229 “Standard Test Method Absorption Properties and Equilibrium Conditioning of Polymer Matrix Composite Materials” test condisions, the CHA Series strain gages are currently available in several uniaxial, tee rosette, and rectangular rosette configurations.
