t actuator with force capacity
t up to ±25 kN (±5620 lbf)
• High-stiffness,
t precision-aligned load frame
t with twin columns and
t actuator in upper crosshead
• 100 mm (4 in) of
t usable stroke
• Designed for both dynamic
t and static testing on a variety
t of materials and components
• Choice of hydraulic
t configuration and dynamic
t performance to suit
tapplication
• Extra-height frame option for
t testing longer load strings
• Adjustable upper crosshead
t with hydraulic lifts and
t manual locks fitted as
t standard for easy
t adjustment of daylight
• Patented1 Dynacell™ load cell
t technology for faster testing
t and reduction of
t
t inertial errors
• Compact tabletop
t servohydraulic fatigue testing
t system – frame requires less
t than 0.4 m² (4.3 ft²) of space
• Optional hydrostatic bearing
t actuators for higher side-load
t resistance or material critical
t applications, such as
t low-cycle fatigue
• Designed to be used with the
t 3520 Series of Hydraulic t
t Power Units
• Compatible with a large range
t of grips, fixtures, chambers,
t video extensometers,
t protective shields, and
t other accessories
Controller and Software
The Instron 8872 is supplied with a digital 8800 controller that
provides full system control including features such as automatic
loop tuning, amplitude control, specimen protect, 19-bit resolution
across the full range of transducers, and adaptive control technology.
It also allows access to WaveMatrix™ Dynamic Testing Software,
Bluehill® Software for static tests and other application specific
software, such as the Low Cycle Fatigue or Fracture Mechanics suite.
