Dynamic Strain Measuring Instruments
Measuring Instruments
Dynamic strain measuring instrument is applied for quickly changing phenomena, and thus different
from static strain measurement, the measured results cannot be read on an indicator. Usually, therefore,
a strain amplifier or signal conditioner is used to amplify strain output, an A/D 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, CST (Capacitance self-tracking) and
thorough environmental tests.
In addition, recent measurement has become complicated and diversified, dynamic strain measuring
instruments has been requiring versatile functions. The multi conditioner MCD-A series meets these
requirements, therefore this 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 frequency conversion type sensors such as a
rotary encoders, piezoelectric sensors, and by combining cards with dedicated unit bases that match
the measuring targets, it is possible to provide a range of types of measurement.
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.
