Torque measurement tools and sensors are common in most industries. These play a massive role in helping operators determine a machine’s friction and rotational conditions. If you’re wondering which torque sensor type to choose for your industry, here’s a quick guide to help you out.
How Torque Sensors Work
Before understanding the differences, pros, and cons of various torque sensors, it’s critical to understand how these transducers work. Torque sensors are highly effective transducing devices that provide a physical variable as an outcome of torque measurement.
In other words, these sensors convert measurements like a torque machine’s dynamic, rotary, or reaction into a variable or electrical signal that an operator can ultimately further measure, convert, and assess.
An increase in torque application escalates the sensor’s performance by changing the electrical output resulting from the meter. These sensors play a critical role in measuring a machinery’s force and capacity to carry various loads.
Rotary Torque Sensor
Rotary torque sensors are also referred to as dynamic torque sensors and are used in areas that require torque measurements for rotating objects. These include rotating engines, spinning shafts, and stationary motors.
The sensor is attached to the shaft so that it can take accurate measurements by rotating with it. Operators use wireless electronics or slip rings to fit the sensor with the machinery so the sensor can adequately covert the readings into electrical signals by rotating consistently.
Rotary torque sensors are highly common for torque auditing and testing in industries with equipment like motors, turbines, and generators. In fact, these devices play a key role in measuring machines’ rotational torque.
Reaction Torque Sensor
On the other hand, static or reaction torque sensors are excellent for massive industrial applications. In other words, industries employ reaction torque sensors for heavy-weight equipment testing or to receive readings from non-moving parts. These sensors work perfectly for machines with limited or no angular motions.
It’s critical to have in-line torque measurements to make the best use of reaction torque sensors. These devices help determine a torque’s friction development, test various structures in mechanics, and assess breakage moments.
