The large-scale utilization of a thing has advantages and disadvantages of its existence, for example, torque sensors have benefits and disadvantages in the development process. Torque sensors, also known as torque sensors, torque sensors, torque sensors, torque meters, are divided into two categories: dynamic and static, of which dynamic torque sensors can also be called torque sensors, non-contact torque sensors.
The following is a brief introduction to the advantages and disadvantages of torque sensors.
First, the advantages of torque sensors
With the continuous improvement and development of the automatic control system, the reliability and response speed of the torque sensor has put forward higher requirements. Torque sensors show the following development trends.
1, the test system is being miniaturized digital, intelligent, virtualization and networking direction.
2, from a single function to multi-function development, including self-compensation, self-correction, adaptation, self-diagnosis, remote setting, state combination, information storage and memory;
3、Development in the direction of miniaturization and integration. The detection part of the sensor can be miniaturized through rational design and optimization of the structure, and the IC part can integrate as many semiconductor parts and resistors as possible into a single IC part, thus reducing the number of external parts.
4, static testing to dynamic online testing direction;
Second, the shortcomings of the torque sensor
The success of the telemetric torque meter lies in overcoming the two shortcomings of the electric slip ring. But there are also three disadvantages.
One is susceptible to the use of electromagnetic waves in the field. Two is because it is battery powered, so it can only be used for a short period of time. The third is that attaching the structure to a rotating shaft tends to cause dynamic balancing problems at high speeds, and is therefore more prominent at small distances and on small diameter shafts. The digital torque sensor absorbs the advantages and overcomes the defects of the above multiple methods, and designs two sets of resolver based on the deformation sensor to realize the non-contact transmission of energy and signal. The transmission of torque signal has nothing to do with rotation or not, nothing to do with the size of the rotational speed, and nothing to do with the direction of rotation.
Third, the main features of the torque sensor are as follows:
Dynamic torque and static torque can be measured. The stability of that check is very good, the anti-interference performance is very strong, and the precision is very good. It does not need to adjust 0 every time when it measures, and it can measure positive and negative torque continuously. Its signal output can be operated by you, you can choose pulse wave or waveform-square wave.
Wide measuring range. There are standards from 0 to 1,000Nm to choose from, and certain non-standards such as 20,00NM, 100,000NM, 100,000NM, etc. can be customized using special range customization. Volume is very small, heavy sensor can be used independently from the secondary instrumentation, only need to be provided by the socket pin number of 15V, -15V power supply can be output with impedance and positive relationship is proportional to the impedance of the pulse wave or other square wave frequency signals, very light, very easy to install.
