Shear Beam Strain Gauges BF350-3HA Series

Shear Beam Strain Gauges BF350-3HA Series

Shear Beam Strain Gauges with V-Shaped Grids HA Series are designed to measure shear strain resulting from torque or torsional loading. They can feature either one or two measuring grids attached to a single carrier. In a single-grid configuration, the strain gauge element is oriented at a 45℃ angle relative to the shaft axis. A two-grid shear strain gauge, also known as a V Rosette, has measuring elements set at 45℃ and 135℃. These gauges are commonly used in applications such as engine shafts and drivetrains, where they can be used to calculate shaft power based on strain measurements.]

Resistance: 350,650,1000 Ohm
Operational temperature －30-＋80℃, Temperature compensation range ＋10-＋80℃
Three (3) to Five (5) solder points,with long-term stability.

V-Shaped Grids: The two grid patterns are oriented at a 90-degree angle to each other, allowing them to respond to the complex shear stress in a component.

Wheatstone Bridge Integration: By wiring these dual grids in a full bridge, bending forces that would otherwise be measured by a single gauge are canceled out, ensuring only the shear strain is detected.

Space-Saving Design: The integrated design allows for accurate measurements in applications where space is limited, such as within torque sensors or small load cells.

Torque Measurement: Used in torque sensors to measure the rotational forces on a shaft.

Shear Force Measurement: Employed in shear beam load cells and other weighing devices to measure forces that cause shear stress.

Transducer Design: Ideal for the internal elements of load cells and other sensors requiring accurate shear or torque detection.

Increased Output: A dual gauge configuration can provide a larger electrical output for the same level of strain compared to a single gauge, leading to higher measurement sensitivity.

Self-Compensation: Many double shear strain gauges are designed with self-temperature and creep compensation to ensure long-term stability and accuracy, especially in sensor applications.

Bending Compensation: When used in a proper Wheatstone bridge, these gauges effectively cancel out unwanted bending stress.
