Standard Semiconductor Strain Gages are made from P doped bulk silicon. They have no PN junction. The Silicon is etched to shape, eliminating the potential for molecular dislocation or cracks, thereby optimizing performance. BAR gage has electrical leads exiting the part from both ends. It is the gage of preference when cost needs to beBased on piezoresistive effect, the semiconductor strain gauges (ScSG) from BCM SENSOR are made from ptype silicon wafers, and are manufactured in two series: Nseries in which the ScSG is made without backing, and Bseries the ScSG with backing. applications of semiconductor strain gauge

For measurements of small strain, semiconductor strain gauges, so called piezoresistors, are often preferred over foil gauges. A semiconductor gauge usually has a larger gauge factor than a foil gauge. Semiconductor gauges tend to be more expensive, more sensitive to temperature changes, and are more fragile than foil gauges.

In this case, the measuring element is directly deposited onto the measurement point under a vacuum by the vaporization of the alloy constituents. The applications are restricted to theapplications of semiconductor strain gauge This static strain gauge module is designed for DC strain measurements in a variety of applications, such as machine monitoring and control in industrial environments and structural monitoring. The NI cFPSG140 gives users programmable

Free Applications of semiconductor strain gauge

Typically, semiconductor gages are first considered for an application where low strain conditions or severe overload requirements are present. Essentially, in areas where a foil strain gage is not suitable, or perhaps simply not ideal, a semiconductor strain gage offers advantages with its high gage factor. Semiconductor gages can also be applications of semiconductor strain gauge
