The 400C series of force transducers is the next generation of our widely used 400A and B series. Advancements include new 2 and 4 channels versions of the amplifier for potential simultaneous measurements and new detachable cables for the sensor heads. This new series, like its B predecessor, has the sensitive signal processing circuitry in the transducer head itself. These new circuits allow any sensor head in the series to be plugged into the control electronics. Researchers can now purchase multiple heads to cover different force ranges, or as spares, and use them with a single controller. Other benefits of the new design are reduced noise, increased sensitivity, and greatly improved linearity.
The 400C series of isometric force transducers enables contractile measurements from a variety of muscle types and sizes and are designed to meet the needs of muscle researchers. Each model is capable of measuring force in both tension and compression. These transducers are more robust and have less compliance than typical semi-conductor strain gauges. Physiologists now have a reliable and more economical way to quickly measure the contractile properties of all muscle types and connective tissue.
There are seven models in the series with the most sensitive model featuring a resolution of 10nN (1 microgram). The range of models allows researchers to measure forces from individual cells, single fibers and whole muscle covering a force range from 0.5mN to 10N.
Researchers can confidently measure force with extremely low compliance (<5µm at full load), eliminating any significant length change in the sample. The design provides excellent thermal stability and minimal sensitivity to vibration and interference. It also provides reliability and ease-of-use without troublesome compensation and filtering techniques
