New Micro-Measurements Bridge Completion Modules (BCM) Improve Quality of Strain Measurements for Broad Range of Applications...
May 27 2020 - 1:38PM
The Micro-Measurements® brand of Vishay Precision Group, Inc.
(NYSE: VPG) (www.micro-measurements.com), today introduced the
MRF-Series Bridge Completion Modules (BCM). Built with Vishay
foil resistors, the most stable resistor technology available, the
MRF-Series improves the quality of strain measurements for a broad
range of applications, such as medical, smart manufacturing,
structural health monitoring (SHM), machine health monitoring
(MHM), and human health monitoring (HHM).
Micro-Measurements is a worldwide industry leader in the field
of stress analysis using resistive-foil sensors for high-precision
strain, high-stress and force mechanism measurements.
Since many general-purpose instruments do not provide internal
bridge completion capability, the MRF-Series of BCMs effectively
implements a full Wheatstone bridge for accurate and stable
measurements when testing specimens structured as a ¼ -bridge
(single gage) or ½ -bridge (dual gages).
“The accuracy of the strain measurement depends on the quality
of the strain gage used, but also on the bridge completion circuit
attached to it. Installing it close to the strain gage and using
Bulk Metal® Foil resistors helps to optimize the measurement
accuracy. Micro-Measurements offers a wide selection of qualified
and dedicated BCM for strain gage sensors that cover the spectrum
of values. The MRF-Series are specially fabricated using Bulk
Metal® Foil resistor technology to meet the highest performance
standards under a wide range of environmental conditions.
These MRF modules are designed to ensure reliable and repeatable
accurate results,” said Ron Zuckerman, Sr. Manager of Sales &
Marketing for Micro-Measurements Advanced Sensors.
The MRF-Series modules are offered in several configurations
that will allow for bridge completion for 120, 350, 1000 and now
5000 ohm quarter-bridges along with half bridge completion as
well.
The small size 1.3 x 0.7 x 0.2 inch (32 x 18.2 x 5.7 mm) allow
for direct installations in tight areas such as medical devices and
printed circuit assemblies. Additionally, at a weight of
only 6 grams, the MRF-Series modules can be installed on rotating
equipment such as drive shafts, draw-bridges, wind turbines, among
other applications. The MRF-Series of BCMs provide other
advantages including minimizing the number of solder connections
required to complete the circuit and decoupling the bridge
completion circuit from any strains present in the underlying
surface.
MRF-Series Bridge Completion Modules employ Vishay foil
resistors which provide an ultra-low temperature coefficient, low
thermal EMF, fast response to current change, and/or low power
coefficient of resistance. This results in a very low resistance
temperature coefficient equivalent to ±0.15με/°F (±0.27με/°C) for
the half-bridge circuits, and ±0.35με/°F (±0.63με/°C) for the dummy
gages, over a temperature range from 0° to +200°F (–18° to +95°C).
Maximum operating temperature range is –50° to +250°F (–45° to
+120°C).
These versatile modules also enables a user to make ¼-bridge and
½-bridge inputs to instrumentation that may not have internal
Wheatstone bridge completion built-in. They are especially
useful when completing the Wheatstone bridge near the strain gage
installation is possible.
