CETR
offers a wide range of solutions to meet your testing, research and analysis
needs for various electrical and electronic components, such as contacts,
connectors, brushes, commutators, etc.
If you wish to perform
your own tests, CETR manufactures and sells the world’s most advanced testers,
backed by a full warranty, outstanding customer service, on-site installation
and in-depth training.
If you would like
testing performed for you, CETR lab performs a wide range of tests to meet
your testing needs. Strict confidentiality of your data is always guaranteed.
Our single-platform,
multiple-configurations fully-computerized UMT testers of the unique acclaimed
modular design can perform practically all common mechanical and tribological
tests of any electrical components with simultaneous measurements of forces,
wear and deformation, electrical resistance and/or voltage drop, which has
made them the most widely used testers for electrical components in the world.
Some
of the typical tests routinely run on the UMT-series testers for electrical
components:
-
durability of electrical
brushes,
-
durability of electrical
contacts and connectors,
-
study of speed, load and
temperature effects on durability,
-
optimization of the
spring-load on electrical components,
-
optimization of materials
for electrical components,
-
design optimization of
electrical components.
The
attached documents list some of the typical applications:
In all these and
numerous other tests, the UMT can perform an automated synchronized control of
several specimen motions with linear speeds from 0.1 micron/s to 30 m/s (7
orders of magnitude!) and angular speeds ranging from 0.001 to 7,000 rpm,
under the precision loads from 1 µN to 1 kN (9 orders of magnitude!). In
these unprecedented wide ranges, the UMT can automatically monitor a number of
process parameters in-situ with a high sampling rate:
-
Normal load (servo-controlled, constant or
changing, e.g., sinusoidal),
-
Friction force, torque and coefficient (static
and dynamic),
-
Wear depth and rate,
-
Deformation depth and rate,
-
Contact and surface electrical contact
resistance,
-
Voltage,
-
Contact high-frequency acoustic emission,
-
Temperature and humidity.
The above tests can be
performed in optional controlled environmental conditions, including
temperature from -25C to 1,000 ºC, humidity from 5 to 95 %RH, various gases,
vacuum (to 10E-6 torr).
