A strain sensor comprises an elastic metal substrate (2) with a strain gauge circuit pattern (1) formed on its surface and a beam (3) having the same thermal expansion coefficient as that of the substrate, the substrate being bonded by an adhesive, such as an epoxy resin, to the beam ...
The invention relates to a circuit arrangement for strain-gauge strips, in the case of which circuit arrangement at least four half-bridges are connected in a parallel circuit to a current source, the potentials of the half-bridges are connected together in pairs, and the potential differences ...
With no force applied to the test specimen, both strain gauges have equal resistance and the bridge circuit is balanced. However, when a downward force is applied to the free end of the specimen, it will bend downward, stretching gauge #1 and compressing gauge #2 at the same time: ...

A strain is usually expressed in μm/m (micrometer per meter), also known asmicrostrain, which has the symbolµε. You may also see “mV/V,” which refers to the output in millivolts per volt of excitation. Strain gages need to be excited or driven with a supply voltage in order...

A semiconductor strain gauge bridge circuit device is disclosed to include a bridge circuit (2) of semiconductor strain gauges, a first zero-point temperature compensation circuit (3) connected to one (b) of a pair of output terminals of the bridge circuit and including a voltage-dividing ...
k = 2.2. The gauge was attached to an unstrained device of the design described above using the same epoxy as for the samples, and was then connected to a home-built balanced Wheatstone bridge circuit in a “quarter bridge” configuration. Together with a second (passive) gauge, this ...
Connect remote sense terminals (RS+ and RS-) to the points where the excitation voltage wires connect to the bridge circuit. For additional details on the remote sensing, configuration refer to the NI-9237 Datasheet. Note: You can program the NI-9237 to supply 2.5 V, 3.3 V, 5 V, or ...
