-100 deg to +400 deg F (-75 deg to +205 deg C)

Strain Range

+ 10% for gage lengths under 1/8 in (3.2 mm)
+ 20% for 1/8 in and over

Fatigue Life

10 ⁴ cycles at + 1000 microstrain
EP-Series gages show zero shift under high-cyclic strains.

Please note : The performance data given here are nominal , and apply primarily to gages of 0.125-in (3-mm) gage length or larger. Reference Table
