2Versatile Chambers Simulate Real-World Conditions

MTS Series 651 Environmental Chambers enable test teams
and researchers to perform a wide array of mechanical tests inconditions that closely replicate the temperatures that materials
and components experience in their actual operating environments,
providing confidence in the operating range of a material in thereal-world.
To ensure accurate and consistent results, MTS chambers aredesigned to maintain a constant temperature within a few degreesof the desired setting and with very little temperature gradientacross the specimen. Heating is achieved with electrical heating

elements and a motor-driven fan for diffused convection heat.
Cooling is accomplished with liquid nitrogen. All chambersfeature a built-in temperature controller and all-welded construction
with Fiberglas™ insulation.
These chambers are engineered to integrate seamlessly with awide variety of floor-standing and tabletop load frames fromMTS, including the MTS Acumen™ Electrodynamic Test Systemand MTS Landmark® Servohydraulic Test Systems, and MTS
controllers, grips and fixtures.

PerformanceControlWith a temperature range of at least 440°C(800°F), chambers in the 651 series cantest as low as -150°C (-238°F) or as highas 540°C (1000°F). Forced convection
heating ensures rapid heat transfer andovershoot protection, while liquid nitrogenprovides efficient cooling.

These chambers have precise temperature
management and optional remote set-point
control to regulate temperature fromthe system PC. The fan, its blades and abaffle help ensure uniform temperatures
throughout the chamber while also
shielding the specimen from direct
exposure to radiant heat.

651.05F-01 chamber
for use on Acumen

Series 651 chambers are ideal for research,reliability testing, quality control andproduction testing. Typical applications
include body and engine mount tests,
tire cord tests, vibration isolator tests andmaterial studies of elastomers, plastics,
polymer matrix composites and laminates.

Engineered for Dependable Operation

Every aspect of Series 651 Environmental Chambers was designed using decades of
MTS experience developing test systems for numerous industries. These environmental
chambers may include:» Circulating fan helps ensures small
specimen temperature gradients» Removable “U-plug” sections allowing
chambers to be moved into place
after the specimen is mounted andinstrumented» Doors that open to 180° or can be liftedaway for convenient specimen access» Multi-panel, tempered optical quality
glass windows are sealed to reduce

fogging and frosting. If required for
non-contacting strain measurement
solutions or video monitoring, thechambers can be provided with
optional defrost elements» Internal light to illuminate the testarea is supported by 651.05 & .06.
651.10 chambers have an external
light mounted to the chamberwindow / door
