Load Cell Electrical Wiring

Load Cell Electrical Components, Connectors, and Wiring Standards

Interface provides technical specifications, pinouts, and wiring documentation for load cells, torque transducers, multi-axis sensors, and instrumentation for each product. Achieving high-accuracy measurement data depends completely on the integrity of the electrical connections between the sensor and the instrumentation. Simple wiring errors or incorrect pin mapping can result in inverted data, thermal drift, or irreversible damage to components in the data acquisition system. Interface Support offers Electrical Wiring and Diagrams resources, including cable, connector, and assembly wiring colors and references.
6 Axis Load Cells 101

6-Axis Load Cells 101

Interface 6‑axis load cells measure forces along three perpendicular axes and the corresponding moments (torque) about those axes. 6-axis sensors are monolithic flexure instruments equipped with specialized strain-gage bridges. The design is engineered to maintain high stiffness while isolating complex loads into independent electrical signals. Standard-capacity sensors utilize six full-bridge channels, while high-capacity models may employ twelve bridges to increase structural integrity and signal resolution. 6-Axis Load Cells 101 reviews the technical performance and features of the advanced load cell used to acquire more data for complex test and measurement programs, including robotics, aerospace testing, automotive components, energy, and medical equipment designs.
Crosstalk

Controlling Crosstalk in Multi-Axis Force Measurement Systems

Interface details the mechanical considerations and best practices for managing crosstalk. Using multi-axis sensors, crosstalk occurs when a load applied strictly to one axis produces a parasitic signal in another. For Interface instrumentation and sensor systems, managing this requires minimizing mechanical coupling at the flexure and applying mathematical compensation through precision electronics.
Hysteresis 101

Hysteresis 101

Interface defines hysteresis as the algebraic difference between the load cell's output at a specific load when approached from an increasing direction versus a decreasing direction. Hysteresis represents a physical limit of the sensor's design. Hysteresis is typically expressed as a percentage of Full Scale (%FS) on a sensor's data sheet or calibration certificate. Learn more about this vital characteristic in Interface's Hysteresis 101.
2 AXIS 101

2-Axis Load Cells 101

Interface 2-Axis Load cells accurately measure forces or torques in two perpendicular directions simultaneously, all from a single, integrated device. The bi-axial sensors include multiple, isolated strain gage bridges within a single sensor body. While a single-axis sensor uses one bridge to measure force along one axis, such as tension or compression, a 2-axis sensor employs additional bridges to produce separate, independent output signals for the orthogonal axes. The primary technical advantage of a 2-axis multi-axis design is the ability to acquire comprehensive, richer data about force interaction from a single measurement point.

INTERFACE 101 3 AXIS LOAD CELLS

3-Axis Load Cells 101

Interface 3-Axis Load Cells measure forces along three mutually perpendicular axes: X, Y, and Z. Interface offers 3-axis load cells with varying capacities, dimensions, and specifications to measure force and torque. The multi-axis sensors require no mathematical manipulation for standard 3-axis force measurements as each signal directly correlates to a specific measurement direction. These advanced load cells are used in aerospace, medical, automotive, automation, robotics, manufacturing and product testing applications.
