Semiconductor Gages | Standard | Un-Backed

Standard Semiconductor Strain Gages are made from "P" doped bulk silicon. They have no P/N junction. The Silicon is etched to shape, eliminating the potential for molecular dislocation or cracks, thereby optimizing performance.

Standard Semiconductor UN-Backed Strain Gages are made from "P" doped bulk silicon. They have no P/N junction. The Silicon is etched to shape, eliminating the potential for molecular dislocation or cracks, thereby optimizing performance.

Standard gages are available in three shapes: "Bar", "U", and "M"

Micron Instruments Standard UnBacked Strain Gages"BAR" gages have electrical leads exiting the part from both ends.
It is the gage of preference when cost needs to be minimum. 

"U" gages are two parallel bar gages in series. This gage is physically and electrically connected on one end with the electrical leads exiting the other end in the same direction.
They are about 25 % more expensive than the bar gage.

"M" gages are four parallel bar gages or two parallel "U" gages with the electrical leads exiting in the same direction.  Cost is twice that of the bar gage.
