Foil strain gage sensors are the primary sensors in many varieties of transducers and the sensing element in stress analysis; their versatility is unmatched in the sensor world. It is possible to measure strain, weight, force, torque, acceleration, displacement, pressure, number of widgets in a box and even the growth rate of a tree -- all with the same Advanced Sensors Technology strain gage type. The ability to weigh items from a few ounces to over 1M pounds is a common application.
Consider the coffee cup you purchase at the store or use for your morning coffee . Did you ever consider how many times strain gages were used prior to pouring coffee into a cup?
Strain gage) technology, as a key internal component of finished sensor designs, is a long-recognized industry standard. The strain gages are used to detect a change in electrical resistance, occurring in response to an applied force. In addition to their reliability, strain gages are relatively compact and low cost. This has facilitated their widespread adoption into many of today’s force, load, position, pressure, tension, weight, and strain sensor designs. Such traditional designs have typically called for the bonding and soldering of anywhere from one to four individual strain gages within a single proprietary configuration. Among these, the full Wheatstone bridge, a four-strain-gage arrangement, has consistently offered the highest measurement accuracy, sensitivity and extraneous temperature cancellation.
The Micro-Measurements product portfolio with Advanced Sensors Technology includes linear, shear and circular gages, arranged as individual, half-bridge and full-bridge configurations, in ranges from 350 Ω to 20 kΩ, with added flexibility in mounting options. The technology improves grid-to-grid tolerances and matching over traditional strain gage manufacturing techniques, enabling better sensor performance. In the case of full-bridge gage configurations, all intra-bridge connections are integrated directly into the pattern itself, eliminating the need for traditional intra-bridge soldering. The addition of gold-plated solder pads improves solder-joint reliability, while reducing the risks of solder pad oxidation prior to lead wire attachment. These processes further ensure the close matching of grid-to-grid thermal characteristics and bridge circuit thermal output cancellation specifications, both of which are essential to strain gage measurement accuracy.
