SS12LA VARIABLE RANGE FORCE TRANSDUCER
SS12LA Sample Setup
SS12LA Variable Range Force Transducer
Force transducers are devices capable of transforming a force into a proportional electrical signal. The SS12LA
variable range force transducer element is a cantilever beam load cell incorporating a thin-film strain gauge.
Because the strain elements have been photolithographically etched directly on the strain beam, these transducers
are rugged while maintaining low non-linearity and hysteresis. Drift with time and temperature is also minimized,
because the strain elements track extremely well, due to the deposition method and the elements’ close physical
proximity. The SS12LA also incorporates impact and drop shock protection to insure against rough laboratory
handling.
Forces are transmitted back to the beam via a lever arm to insure accurate force measurements. Changing the
attachment point changes the full scale range of the force transducer from 50g to 1000g. The beam and lever arm
are mounted in a sealed aluminum enclosure that includes a 3/8" diameter mounting rod for holding the transducer
in a large variety of orientations. The SS12LA comes equipped with a 2-meter cable and plugs directly into the
MP3X module.
The SS12LA mounting rod can be screwed into the transducer body in three different locations, two on the top
and one on the end surfaces of the transducer. The mounting rod can be placed in any angle relative to the
transducer orientation. The SS12LA can be used in any axis and can be easily mounted in any standard
measurement fixture, including pharmacological setups, muscle tissue baths and organ chambers.
The SS12LA has 5 different attachment points that determine the effective range of the force transducer. These
ranges are 50g, 100g, 200g, 500g and 1,000g. The point closest to the end is the 50g attachment point, while the
point closest to the middle is the 1,000g attachment point.
Two
S-hooks
are provided with the SS12LA; one has a .032" diameter
wire and the other has a .051" diameter wire. The smaller hook is to be
used for the 50g, 100g and 200g ranges. The larger hook is intended for
the 500g and 1000g ranges. The larger hook is intentionally a tight fit to
generate a downward pull vector. To further increase proper readings,
keep the unit level and align anything that hangs off the hook straight
beneath it rather than at a sideways angle.
