Materials are subjected to extreme stresses. However, are they able to withstand them?
Experimental stress analysis is the method of choice for
measuring material strain and determining mechanical stress.
The experimental QuantumX MX1615 is a powerful, universal amplifier that is now
available for your experimental stress analysis needs.
Benefit from sixteen individually configurable channels in a compact
housing.
Adjust different sampling rates in your channels - from quasi-static
through dynamic.
Use various transducer technologies to acquire data, for example full, half and
quarter bridges, voltage and temperature - all in one amplifier module. All from a
single source: Benefit from a factory-calibrated measuring chain
and easy transducer connection using TEDS.
The amplifier's high resolution enables you to acquire even the "smallest events".
MX1615 offers exceptionally high temperature stability
because it supports the secure four-wire configuration of strain gauges.
This is demonstrated by our experiment involving installed strain gauges and a
QuantumX MX1615 module.
Regardless of whether you're measuring point is subjectet to low or high
temperatures - the measurement results of the patented four-wire configuration
represented by the blue graph are reliable und precise. The results of the
two-wire configuration represented by the red graph are no longer significant.
Reliability in temperature stability thanks to the patented
four-wire configuration: A factor of primary importance, when you take
measurements at varying temperatures.
A key benefit provided by the MX1615 is its four-wire configuration
for reliable and significant measurement results in experimental stress analysis.
In our experiment, we simulate asymmetric changes in resistance on the
strain gauge wires that are also frequently found in actual installations.
Two-wire configuration:
the result is not stable. Changes in resistance are not corrected. Three-wire
configuration: The result is not stable. Changes in resistance a corrected in
one cable only. Four-wire configuration using MX1615:
The result is stable and reliable. With temperature variations, too.
Changes in resistance are corrected in both cables.
Yet another advantage: MX1615 offers outstanding immunity to
radiated electromagnetic interference. Your measurement results remain stable
thanks to the carrier frequency technology
developed by HBM. In another experiment we use a solenoid to
subject the strain gauges to electromagnetic interference. Red: Results
without using carrier frequency technology: The result is unusable.
Blue: Results of MX1615
using carrier frequency technology:
Secure, reliable, electromagnetic interference does not affect the
measurement results, since the frequency of electromagnetic radiation
is outside the carrier frequency range. A major benefit the measurements, for
example in rail traffic and power lines.
Benefit from using catmanĀ®AP software from HBM: Easy to use,
offering many functions for experimental stress analysis. Including,for example, a
very useful sensor database and integrated rosette calculation.
