1. Determination mechanism
The commonly used torsional strain gauge is attached to the ductile shaft to be measured with strain adhesive and forms a strain bridge, which supplies power to the strain bridge. The electrical signal of torsion on the elastic shaft is immediately determined. After the strain signal is enlarged, it becomes a frequency signal with the positive and negative shares of the torsional strain after the voltage/frequency change. The input of renewable resources and the output of signals in the ontology are carried by the common ring transformers with open space in two pairs, so they insist on the role of non-touch renewable resources and signal transmission.
2. Characteristics
1. It can not only measure the uniform motion torque, but also measure the rolling rotation distance;
2. It can not only measure non-static torque, but also determine static torque;
3. High precision and good reliability; Strong anti-interference ability;
4. Light weight, very light, various installation structures, easy to install and apply;
5. It is possible to continuously measure the forward flip torque without constant zero adjustment;
6. There are no damaged parts such as thermal conduction rings, and can operate at high speed for a long time;
7. The high-level frequency signal output by the sensor can be sent to the computer for processing immediately;
8. Measure the strength of the elastomer and can bear 100% of the load.
3. Sensor principle structure
The commonly used torque-measuring sheet is pasted on the ductile shaft of each section of the sauce and forms a variable bridge, which is the fundamental torque sensor; On the shaft, it is determined: (1) the secondary coil of the renewable resource toroidal transformer, (2) the primary coil of the signal toroidal transformer, and (3) the printed circuit board on the shaft, which includes the rectifier stable electrogen, the sense meter expansion circuit, the V/F conversion integrated op amp and the signal output circuit.
