1. Introduction:
What is a Six-Axis Force/Torque Transducer?
A device that measures the outputting forces and torques from all three Cartesian coordinates (x, y, and z). A six-axis force/torque transducer is also known as a multi-axis force/torque transducer, multi-axis load cell, F/T sensor, or six-axis load cell.
The loads applied to a Brans sensor are quantified into six components. The diagram below shows the three forces and three moments that are measured as they are applied directly or indirectly (through an attached object) to the top surface of the sensor.
Forces Fx, Fy and Fz are the force components. The forces are named according to the axes of a conventional x, y, z-coordinate system. Each component is therefore looked at as positive or negative along the x, y and z axes. In the diagram, the arrows point toward the direction of positive or compressive force along each of the axes. Fx and Fy are the horizontal or shear force components. Looking at the connector, the Fx axis is oriented from right to left and the Fy axis is oriented from front to back away from the connector. Fz is the vertical force component and points down.
Moments Mx, My and Mz are the other three components. Moments are rotations around the same x, y and z axes and they follow the right hand rule.
Together the six components can be used to examine the complex forces being exerted upon the sensor.
This one can be modified or customized to meet your requirements. Similar to our entire multi-component load cell series, this model is manufactured in China and utilizes metal foil strain gauge technology.
The BRANS Multi-Axis Force/Torque Sensor system measures all six components of force and torque. It consists of a transducer, interface electronics and cabling.
Transducer
The compact and rugged monolithic transducer uses silicon strain gages to sense forces. The transducer's silicon strain gages provide high noise immunity and allow high overload protection, which is standard on all models.
2. Applications:
- Mainly used for force control in milling or grinding machine, rototic polishing and other industrial measuring system, production of high accuracy components, assembling; Measuring and controlling for all directions
3. Product Highlights:
(2) High signal-to-noise ratio: provide a signal 75 times stronger than conventional foil gages. This signal is amplified resulting in near-zero noise distortion.
(3) Prompt delivery of standard F/T models.
(4) Custom F/T transducers can be designed and built to your specifications.

Built-In Capabilities
The Net F/T, DAQ F/T, Controller F/T, and TWE F/T each provide a variety of powerful functions:
Tool transformations translate and/or rotate the F/T reference frame.
Demo software allows configuration and basic data logging capabilities.
Biasing provides a convenient way to offset tool weight.
Increased system throughput is possible by reducing the number of axes of output. (Not applicable to the Net F/T or TWE F/T.)
Threshold detection eases integration into industrial applications (Net F/T and Controller F/T only).
We are happy to work with your design needs - providing a custom design if warranted for varying capacities (between X-Y and Z), higher temperature capability, or OEM/private labeling if needed.
