On solid frame straight side machines,
the preferred strain gage mounting
location is inside the "windows" under
the ends of the crankshaft. A strain
gage should be mounted on the inside
face of each column forming the
"windows" as shown in Figure 31.

6.7 Strain Gage Mounting
Strain gages may be bolted directly to the machine or bolted to intermediate pads welded or adhered to
the machine.
6.7.1 Direct Machine Mounting
1) Select the desired mounting locations for the strain gages.
2) Remove paint, oil, grease, etc., to obtain a bare metal surface slightly larger than the LST-1000
strain gage. The metal surface must be flat and smooth so that the strain gage is not warped and
contacts the surface area evenly when mounted. A mounting surface that is flat to within .0025
inches and with a 250 micro-inch or less finish will give best results. Grind the surface if
necessary.
3) Scribe a line on the metal surface on which the strain gage is to be mounted in the direction of
tension or compression of the structural member. This will be a vertical line on columns or tie
rods of straight side presses and "C" frame machines that are not inclined. On inclined presses,
the scribe marks should follow the inclined angle.
