MALVERN, Pa.--(BUSINESS WIRE)--
Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay
Foil Resistors brand (VFR) has released a new video that explores using
VFR Bulk Metal® Foil commercial off-the-shelf (COTS)
resistors to calibrate and maintain the accuracy of precision
temperature measurement systems utilizing resistance temperature
detector (RTD) sensors. The short video demonstrates the selection and
use of foil resistors to simulate physical parameters in the calibration
of RTD-based temperature measurements, and how the ultra-low-TCR
precision resistors are nearly immune to drift over temperature and
time, serving as the ideal reference to check against the RTD under any
operating condition. With Bulk Metal Foil resistors, RTD-based systems
can be recalibrated in harsh environments and hold their accuracy for
several years.

RTD measurement instrumentation must maintain calibration regardless of
the end user or application. Ultra-precision temperature accuracy is
required for extended periods of time in a variety of extremely harsh
environments, such as oil platforms, deserts, and the Antarctic.
Resistors used in these applications must be rugged and impervious to
heat and humidity, with low absolute TCR to simulate perfectly the value
of the RTD at defined temperatures. Traditional standard resistors,
however, are expensive, fragile, and do not provide the accuracy
required.
The demo video highlights the characteristics of VFR's Bulk Metal Foil
resistors for RTD calibration. RTD-based systems can be recalibrated
with precision foil resistors instead of expensive certified physical
standards, even in extreme operating environments. Rugged,
tight-tolerance foil resistors with TCR of only 0.2 ppm/°C from -55°C to
+125°C and a long-term stability of 2 ppm per year (worst case) can be
supplied to the exact resistance necessary to duplicate platinum,
nickel, and copper temperature sensors at critical temperatures.
Available with a hermetic seal 0066or ruggedness, the compact resistive
devices can be trimmed to unique resistance values. Any conceivable
ohmic value to six digits is available with an absolute tolerance to
±0.001%. Due to the devices' convenient built-in calibration factor,
these values can be provided in only a few days at a low cost.
