Strainsert Load Sensing Actuator Clevis Pins, SPHC Series
The Force Sensing Actuator Clevis Pin 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 clevis pins and clevis bolts
offer precision force measurement and monitoring by replacing existing clevis pins
in hydraulic cylinder/actuator hardware.

The Strain gages are sealed inside small axial holes within the load pin
and are positioned at two locations at the hydraulic actuator 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. In place calibration check
recommended.

| Some Features Include: |
| · Easy Installation: By replacing pins in hydraulic
cylinders with minimum alterations using keeper plates. |
· 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 pin,
by exclusive Strainsert process. |
· Accuracy: Strainsert force sensing actuator clevis pins
have combined error due to repeatibility and non-linearity of less
then 1% of rated load typically. |
