Section 2 :
Equipment Supplied
Strain Gauges come supplied at pre-set readings dependent on the expected magnitude and direction
of strains to be recorded.
Each gauge is supplied with a user specified length of cable moulded to the gauge sensing coil and a
securing clamp. The cable can be spliced to other cables for routing to a terminal location. Cables can
be routed over distances in excess of 1000 metres without degradation of signal.
Each gauge is supplied with a thick walled silicon rubber sleeve over each barrel (see Figure1) to
protect the gauge barrel when it is tied to support bars during mounting.
Although gauges are checked prior to leaving Soil Instruments, damage can occur during transit. It
is suggested that the gauges are visually checked immediately upon receipt. Additionally it is
prudent to check the operation using a vibrating wire readout device to ensure steady readings, if
an audio signal is available on the readout device this can give a good indication of the quality of
the signal.
Prior to installation secure the coil assembly to the gauge using the securing clamp as shown
above.
Before installation, a note should be made of the batch factors for the Strain Gauges for future
data interpretation.
