Micro-Measurements®, part of the
Vishay Group, have a new, optional pre-attached Teflon leadwire for its CEA- and WK-series strain gauges, Option SP35, in support of high-temperature stress analysis requirements to +400°F (+204°C).
A key benefit in the specification of pre-cabled gages for stress analysis is their efficiency during installation. With this new option, Micro-Measurements has extended this benefit into higher application temperatures. New Option SP35 includes ten feet (three meters) of 30-AWG, twisted, etched Teflon leadwires (330-FTE). The etching ensures that any protective coatings applied over the installation will bond and seal to the cable. Gauge leadwires are pre-attached via solder to the CEA- and WK-series strain gages, allowing them to support specific requirements to +350°F (+177°C) and +400°F (+204°C), respectively. Their three-wire quarter bridge configuration cancels any potential cable thermal output which may occur in response to temperature changes.
Option SP35 is ideal for the support of higher temperature stress analyses of automotive and aerospace components, or of any other structural material. It is particularly useful for higher temperature composite materials testing, eliminating the need for soldering on the test article, and thus the possibility of heat damage to sensitive surfaces.
In addition, Option SP35 has no impact on strain gage resistance tolerance or strain range specifications, allowing for continued seamless integration into the application environment. At the same time, it offers a viable leadwire solution with simplified installation requirements. With these combined features, Option SP35 now allows a customer to specify both Micro-Measurements CEA- and WK-series strain gages into an expanded number of higher temperature applications, particularly those where the limitations of traditional pre-gaged vinyl insulated cabling had previously limited their use.
