Measurement of torque:
Using strain gauge electrical measurement technology. A strain bridge is formed on the elastic shaft, and the electric signal of the elastic shaft being twisted can be measured by supplying power to the strain bridge.
After the strain signal is amplified, it undergoes pressure/frequency conversion. becomes a frequency signal proportional to the torsional strain. as the picture shows:
Measurement of rotational speed:
The rotational speed is measured by the method of magnetoelectric code disc. Each magnetoelectric disc has 60 teeth. The shaft drives the magnetoelectric code disc to generate 60 pulses per revolution. The accuracy of the speed sensor can reach ±0.1%～±0.5% (F•S).
The speed measurement method of this sensor adopts built-in speed measurement, please indicate whether to monitor the speed signal when ordering!

The selection of the torque sensor range should be based on the actual maximum torque measured. Usually there should be some margin. Prevent damage to the sensor due to overloading.
Calculation formula: M=9550×P/N
M: Torque Unit: N.m
P: Motor power unit: KW
N: Speed Unit: r/min
If the motor you are using is a three-phase induction motor. Due to the large instantaneous torque of the motor starting. It is recommended that the torque range should be selected to be 2-3 times the rated torque.
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 axes of the prime mover and the load relative to the reference plane, so that the coaxiality of their axes is less than Φ0.03mm, and fix the original Motives and loads are 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 between its axis and the axis of the prime mover and the load is less than Φ0.03mm, and fix the torque sensor on the reference plane.
Tighten the coupling and the installation is complete.
A torque sensor is a force measuring device and torque measuring tool. It converts a torque measurement (static, dynamic or rotational) into another physical variable. In this case, into an electrical signal that can be measured, transformed and normalized. As the torque applied to the torque sensor increases, the electrical output signal changes proportionally.
Classification of torque sensors:
Dynamic Torque Transducers / Rotational Torque Transducers
Dynamic torque sensors/rotating torque sensors are used in applications where torque measurement must be performed on rotating shafts, engines or stationary electric machines. In this case, the transducer must rotate on a straight line connected to the shaft. Dynamic torque sensors are equipped with slip rings or wireless electronics that transmit torque signals while rotating (non-contact sensors).
Dynamic torque sensors/rotational torque sensors are often used as test tools for electric motors, torque measurement tools, turbines and generators to measure rotational torque. Shaft-to-shaft rotational torque sensors can also be used for feedback control, monitoring torque, analyzing test bench efficiency, and using strain gauges for torque measurements on rotating shafts.
The dynamic torque sensor/rotation torque sensor is also an important part of the dynamometer. Because it provides torque measurement and angular velocity (RPM), it can easily calculate the output power. So it can accurately calculate the electromechanical efficiency of the motor or engine.
Static torque sensor
In some applications, a static torque sensor can be used to measure the torque measurement made by an in-line rotary sensor (static torque measurement) at the point where the torque is transmitted to the ground.
A reaction torque meter has two mounting flanges (flange-to-flange transducers). One face is fixed to the ground or rigid structural member. The other face is fixed to the rotating shaft or rotating element. Rotation creates a shear force between the flanges. This shear force is captured by foil strain gages attached to the sensor beam. It is converted into electrical current through a Wheatstone bridge.
For a given application, static torque sensors (aka torque sensors) are generally not as sophisticated as rotary sensors. So less expensive than rotary sensors. Static torque transducers are often used as torque calibration tools or torque wrench calibration tools. Static torque sensors can also be used as miniature electric torque screwdrivers, allowing engineers to obtain torque feedback in real-time, or to study the torque applied during assembly.
Non contact torque sensor input shaft and output shaft are connected by torsion bar. There are splines on the input shaft and keyways on the output shaft.
When the torsion bar is twisted by the turning moment of the steering wheel, the relative position between the splines on the input shaft and the keyway on the output shaft is changed.
The relative displacement change of the spline and the keyway is equal to the torsion of the torsion rod, which makes the magnetic induction on the spline change. The change of the magnetic induction is converted into a voltage signal through the coil.
The high frequency part of the signal is filtered by the detection circuit and only the torque signal part is amplified.
Due to the non-contact working method, the non-contact torque sensor has a long life and high reliability. It is not easily affected by wear, has a smaller delay, and is less affected by the deflection of the shaft and axial offset. It has become widely used. Mainstream products of the application.
