315C/322C: High-Speed Length Controllers

The 315C/322C high-speed length controller allows complete automated control of length measurements to assess the dynamic properties of non-biological specimens such as natural and synthetic polymers, fibers, films and coatings. Our length controllers can also be used to stretch artificial muscle, spider silk and other biological tissues including plant cells.

These controllers provide a range of lengthcontrol and response times uniquely suited to answer a number of researcher questions. Our fastest model, the 315C, can change length in as little as 200µs and has a length frequency response up to 2.4 kHz. All models allow the researcher to resolve lengths as small as 1 micron. Integrator models (315C-I and 322C-I) have less than 0.01 micron/mN isometric compliance. With tensile limits of 300mN and 200mN, respectively, our  high-speed length controllers have more than enough force for any tissue sample.

In addition, front panel manual length control allows the researcher to set the steady-state arm position, while the circuit design prevents the motor from being operated beyond its safe limits.
