Dynamic Strain Measuring Instruments
Dynamic strain measuring instruments are applied for quickly changing phenomena, and thus different from static strain measurement: the measured results are not to be read on an indicator. Usually, therefore, a strain amplifier or a signal conditioner is used to amplify strain output, an AD converter and a PC are used to record and analyze the data.
Dynamic strain measurement requires response, stability, SN ratio and high resistance against external noise. Kyowa's dynamic strain measuring instruments satisfy these requirements with advanced technologies including high performance ICs, high density circuits and CST (capacitance self-tracking).
In addition, as recent measurement has become complex and diversified, dynamic strain measuring instruments are required to have versatile functions.
The multi signal conditioner MCF-B series meets these requirements. It supports conditioner card usage with not only strain gages and strain-gage transducers (load cells, pressure transducers, displacement transducers, acceleration transducers, and torque transducers), but also thermocouples. And combining the cards that match the measuring targets with the dedicated unit base, it is possible to cover a wide range of measurements.
Depending on the bridge excitation, dynamic strain measuring instruments are classified into two types: AC and DC. Kyowa names the AC type a strain amplifier and the DC type a signal conditioner.
AC type strain amplifiers are suitable for measuring small strain from strain gages, and DC type signal conditioners are for measuring large strain from transducers. DC type signal conditioners are further classified into constant-voltage and constant-current systems. The constant-current system is suitable for measurement with extension cables.
