Glossary

Definition
Biasing is useful for eliminating the effects of gravity (tool weight) or other acting
forces. When the bias function is used, the software collects data for the forces
and torques that are currently acting on the sensor and use these readings as a
reference for future readings. Future readings will have this reference subtracted
from them before they are transmitted. Bias may also be referred to as "zero out"
or "tare"the sensor.
Defines a specific measurement or sensing range for a given sensor. Calibration
is also the process of measuring a transducer's raw response to loads and
creating data used in converting the response to forces and torques.
Any load that is not purely in one axis.
The software standard that the customer device uses to apply features to the
sensor and for the sensor to report data, for example: EtherCAT, RS422, and
Ethernet.
See Sensing Reference Frame Origin.
How fast data can be output over a network.
A force is a push or pull action on an object caused by an interaction with
another object. Force = mass x acceleration.
Full-Scale, refers to the limits of a given calibration or sensing range.
Force/Torque.
The resultant force vector comprised of components F
A source of measurement error caused by the residual effects of previously
applied loads.
A separate plate that attaches the sensor to another surface. Interface plates are
often used if the bolt pattern on the sensor doesn't match the bolt pattern on the
robot arm or customer tooling. The interface plate has two bolt patterns, one on
either side of the plate. One side is for the sensor. The other side is for the robot
arm or customer tooling.
Ingress protection rating "64" designates protection against dust and splashing
of water. An IP64 rating does not guarantee protection when a user submerges a
device in water or any type of fluid.
A customer supplied device such as a personal computer, robot, or
programmable logic controller (PLC) that is compatible a specific communication
interface.
Commonly referred to as "accuracy", "measurement uncertainty" is the worst-
case error between the measured value and the true load. The measurement
uncertainty is specified as a percentage of the full-scale measurement range for
a given sensor model and calibration size. This value takes into account multiple
sources of error. The sensor's calibration certificate lists the measurement
uncertainty percentage. For more information, refer to Section 2.2: Measurement
Uncertainty in the Frequently Asked Questions (FAQ) document located at:
https://www.ati-ia.com/library/documents/FT_FAQ.pdf.
When an external object such as customer tooling or utilities contacts a sensor's
surface between the sensor's mounting side and tool side.
An interface plate that attaches the sensor to a fixed surface like a robot arm.
Not Applicable
The condition where more load is applied to the transducer than it can measure.
This will result in saturation.
