Hand-held Force Gauge L-Bracket Adapters
Calibrating hand-held force gauges in regular calibrat
-
ing machines can be cumbersome and involves a risk
of overloading the gauge. Hand-held force gauges are
normally manufactured for measuring small forces,
which are difficult to generate and maintain in a large
force calibrating machine. A small, sudden increment
in the applied force can result in overloading the
instrument under test and reference standard. Such
incidents can be costly and cause long down times.
The Portable Calibrating Machine addresses this issue
by providing a highly precise force control and elimi
-
nating sudden increments in applied force.
Morehouse offers a set of L-Bracket adapters to
calibrate hand-held force gauges in a Portable Cali
-
brating Machine. The L-Brackets consist of a number
of back-plates, bottom-plates, and treaded adapters
to mount various models of hand-held force gauges.
Each back-plate can be mounted to any bottom-plate
to make different combinations. Each back-plate is
designed with special hole patterns to accommodate
various types of hand-held force gauges.
The force gauge is mounted to the back-plate
through the hole pattern and the back-plate is di
-
rectly mounted to the bottom-plate. Bottom-plates
have a threaded hole at the center with 0.625”-18
UNF-2B thread which is used to install the L-Bracket
and hand-held force gauge assembly directly to the
reference standard load cell in a Portable Calibrating
Machine. Bottom-plates are included with various
mounting hole offsets from the edge. Based on the
type of hand-held force gauge, the proper bottom
plate must be used to ensure the line of applying
force in the calibration set up aligns with the force
gauge’s load line. A threaded adapter is utilized to
attach the loading rod of the hand-held force gauge
to the coupling nut in a Portable Calibrating Machine.
