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’ 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 performance under ASTM-5229 “Standard
Test Method Absorption Properties and Equilibrium Conditioning of
Polymer Matrix Composite Materials” test conditions, the CHA Series
strain gages are currently available in several uniaxial, tee
rosette, and rectangular rosette configurations.
CHA features and benefits are:
- Cast polyimide backing for flexibility and toughness
- Larger integral copper coated tabs for easier leadwire
connection
- Protective encapsulation film with enhanced moisture protection
for the most demanding applications
- Strain range: ±3% for all gage lengths, 5% for gage lengths of
0.250 inch or greater
- Fatigue life: ±1500 microstrain for 10^6 cycles
- Temperature range: –100° to +350°F (–75° to +175°C)
