S. Himmelstein and Company’s square drive reaction torquemeters are designed to meet the demands of calibrating and testing heavy-duty power tools across industries such as mining, construction, and energy production. As the scale of your fastening equipment grows, so must your torque measurement tools, and our torquemeters are engineered to handle the most rigorous applications.
Durable, Robust, and Highly Accurate
Our square drive reaction torque transducers utilise strain gauge technology to measure torsion with precision. These strain gauges are made from high-quality thin wire, which changes electrical resistance in response to compression and extension. Mounted at a 45-degree angle to the rotational axis, the transducers effectively minimise the impact of extraneous forces. The four-gauge Wheatstone Bridge configuration ensures a precise output signal that is directly proportional to the applied torque.
Optimised for Measuring Reaction Torque
Designed for applications involving large square drives, our square drive reaction torque sensors offer exceptional accuracy and reliability. The Model 2208 features a 4" square drive, while the Model 2209 provides a 5 ½” AF square drive. Compact yet powerful, these units are perfect for calibrating and testing high-torque devices used in industries such as energy production, mining, and heavy equipment manufacturing.
Key Features of Our Square Drive Reaction Torquemeters:
- High Capacity: Models 2208 and 2209 can measure up to 3,000,000 lb-in of torque.
- Overload Protection: Rated for up to 200% overload capacity to handle sudden load spikes without compromising accuracy.
- Robust Design: Expertly designed to absorb high extraneous loads in thrust and bending directions, ensuring long-term durability.
- Calibrated for Precision: Calibrated in both clockwise and counterclockwise directions with a combined error of less than 0.25% of range (excluding Model 2208M).
- Temperature Compensation: Maintains accuracy in varying conditions.
- Versatile Operation: Operates on a 15V AC or DC supply with an analog output of 3mV/V.
Our square drive reaction torquemeters deliver the reliability and accuracy you need for testing and calibration in the toughest environments.
