Torque Sensor
A torque sensor measures and monitors the torque applied in a rotating system. They are often used in engine, crankshaft, gearbox, transmission, & rotor. The torque required to break down a rotating shaft is called static torque. Whereas, the torque required to rotate the shaft of a motor is called dynamic torque. It is easy to measure static torque. A dynamic torque measuring device has to take some other effects (hydraulic, electric, or magnetic) into consideration as well.

Common Components and Technology Used in Torque Sensors
Strain Gauges
These are the most common components in torque sensors. Strain gauges are thin wires or foil patterns applied to a surface. When torque is applied, the strain gauge deforms, causing a change in its electrical resistance. This change in resistance is measured and correlated to the applied torque.
Rotating Shaft
In many torque sensors, a rotating shaft is used to transmit torque from the source to the sensor. This shaft is usually made of a durable material like steel and is designed to withstand high torque loads.
Signal Conditioning Circuitry
To accurately measure the small changes in resistance or other properties caused by torque, torque sensors often include signal conditioning circuitry. This circuitry amplifies and processes the sensor signals before they are sent to data acquisition systems for further analysis.
Housing and Mounting Mechanism
Torque sensors are typically housed in sturdy enclosures to protect them from environmental factors and mechanical stress. They also include mounting mechanisms to securely attach them to the system being measured.
Torque sensors operate based on the principle of measuring the deformation caused by applied torque. When torque is applied to a sensor, it induces a twist or strain in the material. This deformation can be quantified using various technologies:
Strain Gauge Sensors: These are the most common type of torque sensors. They consist of a shaft with strain gauges attached. When torque is applied, the shaft deforms slightly, causing a change in resistance in the strain gauges. This change is measured using a Wheatstone bridge circuit and converted into an electrical signal.
Magnetoelastic Sensors: These sensors utilize changes in magnetic fields caused by applied torque to generate an electrical output.
Optical Sensors: These use light to measure changes in position or angle due to torque.
Surface Acoustic Wave (SAW) Sensors: These sensors measure minute changes in surface strain using acoustic waves, providing high sensitivity and accuracy.
According to the connection form of the shaft and the length of the torque sensor, determine the distance between the prime mover and the load, adjust the distance between the axis of the prime mover and the load relative to the reference plane, so that the coaxiality of their axes is less than Φ 0.03mm, The concentricity shall not exceed 0.1mm, and the prime mover and load shall be fixed on the datum plane.
Install the couplings on their respective shafts.
Adjust the distance between the torque sensor and the reference plane so that the coaxiality of its axis with the axis of the prime mover and the load is less than Φ 0.03mm, and fix the torque sensor on the reference plane.
Fasten the coupling and the installation is complete.
Routine Care for Sensor Accuracy
Calibration
Regularly calibrate your torque sensors to ensure their accuracy and reliability. Calibration standards vary by industry, but generally, an annual check is recommended.
