Standard Force Sensing Shackle Load Bolts, RCP Series
The Force Sensing shackle bolts are unique strain
gage transducers utilizing the internal strain gage transducer
process developed by Strainsert and used also in their Flat Load
CellsŪ and Tension Links. These shackle bolts
offer precision force measurement and monitoring by replacing existing pins or
bolts in standard Crosby anchor and chain shackles.

The Strain gages are sealed inside small axial holes within the load pin
and are positioned at two locations at the shackle interfaces. In order to
sense only those strains which are induced by the shear forces at
these two sections, the strain gages are positioned and oriented with
great precision, at a neutral plane relative to one specific direction
of pin loading.
The four strain gages (two at each location) are electrically
connected to form a full bridge, the signal from each strain gage being
additive so that the bridge output is proportional to the sum of the loads
transmitted by the shear planes of the pin. The circuit typically includes
temperature compensating, signal trim (optional) and balance resistors
terminating in suitable connector socket or integral cable, and potted
with a sealing compound inside the gage hole, for enhanced environmental
protection.
Standard models include detailed calibration
data up to 500,000 lbs. Higher capacity calibration data is available at an additional
charge. An in-place calibration check is recommended.

| Some Features Include: |
| · Easy Installation: RCP and SCP series replace
standard Crosby or Skookum shackle bolts/pins respectively. |
· Durability: Due to self protecting nature of
strain gage installation sealed inside small holes. |
| · Precison Load Sensing:Complete strain gage
bridge circuit bonded and sealed inside small hole along longitudinal axis of bolt,
by exclusive Strainsert process. |
· Accuracy:Strainsert force sensing load or clevis
bolts have combined error due to repeatibility and non-linearity of less
then 1% of rated load typically. |

The clevis pins or clevis bolts are extremely durable under even the most severe conditions and working environments.
These products have a wide range of applications, have a long
operational life. and are currently used on many installations where force
measurement in a shackle application is required.
