Torque wrenches are what type of measuring device?

• A. Electronic meters
• B. Precision measuring devices
• C. Pressure gauges
• D. Speed measuring devices

Answer: (B)

Torque wrenches are designed to measure and control the turning force applied to a fastener, so they are precision measuring devices. They provide a calibrated indication of torque, typically in Newton-meters or pound-feet, and are built for repeatable accuracy within a specific range. This emphasis on quantifying a mechanical quantity with tight tolerances is what makes them precision measuring instruments. They aren’t electronic meters, which measure electrical signals; they aren’t pressure gauges, which measure pressure; and they aren’t speed measuring devices, which track rotational speed. Some models may include digital readouts, but the essential purpose remains to measure torque with high accuracy.
