How to choose the torque sensor reasonably

        The sensitivity of the torque sensor is specific, when the precise measurement is a unilateral amount, and its specificity requirements are high, then you should choose other directions of the torque sensor sensitivity is small, if the precise measurement is multi-level space vector, the lower the sensitivity of the cross-type torque sensor is required the better. The characteristics of the torsion sensor should be made taking into account the application requirements.

        Torque sensors are one of the basic electronic components that are indispensable in the industrial automation manufacturing industry. The enhancement and improvement of its characteristics is a top priority for most people. The dual nature of the product can take into account the provisions of the consumer, this has long become the majority of torque sensor production and manufacturing business reception necessary to solve the research problem. Because the current stage of the current market torque sensor in the structure and basic principles are different. How to reasonably choose the torque sensor according to the specific purpose of accurate measurement, the overall goal of accurate measurement and the geographical environment of accurate measurement is the most difficult point to be solved at the beginning of a certain amount of accurate measurement. When the torque sensor is established, the matching precision measurement method and precision measurement machinery can also be established. The success or failure of accurate measurement results depends to a great extent on whether the selection of the torque sensor is reasonable. The general choice of torque sensor must have the following six points of specification.

1.>Establishing the type of torque sensor based on the overall goal of precision measurement and the geographic environment of precision measurement

        To carry out a specific precision measurement work, the first to fully consider which basic principle of the torque sensor, which must be established after analysis of various factors in the field. Because, even if the precise measurement of the same scalar, there are a variety of basic principles of the torque sensor can be used, which is more suitable for the basic principles of the torque sensor, it must be based on the characteristics of the precise measurement and the use of torque sensor specifications to fully consider the following specific difficulties: ① specifications of the detection range ② measured location of the torque sensor capacity requirements ③ measurement method for the capacitive grid or non-contact ④ signal lead over method, cable TV should be energetic touch accurate measurement ⑤ torque sensor from, China or imported, whether the price can receive love, or the need for independent research and development.

2.> The choice of sensitivity

        Generally, in the range of torque sensor line, hope that the higher the sensitivity of the torque sensor, the better, because only when the sensitivity is high, the value of the output signal in line with the precise measurement of the change is relatively large, which is conducive to digital signal processing. However, it should be noted that the high sensitivity of the torque sensor, with the precise measurement of irrelevant external noise is also easy to penetrate, will also be increased by the system, harming the measurement accuracy. Therefore, the torque sensor itself should be required to have a high frequency stability to minimize the interference signal introduced from the outside.

        The sensitivity of the torque sensor is specific, when the precise measurement is a unilateral amount, and its specificity requirements are high, then you should choose another direction sensitivity of small torque sensor, if the precise measurement is multi-level space vector, the lower the sensitivity of the cross-type torque sensor is required the better.

3.>Phase-frequency characteristics

        The phase frequency characteristics of the torque sensor management decision to be measured accurately in the frequency range, as far as possible in the allowable frequency range to maintain accurate measurement specifications without distortion, in fact, the response of the torque sensor will have a certain time delay, hope that the lower the delay time is the better.

        Torque sensor phase frequency characteristics of high, the measurable signal frequency range is wide, and due to be hurt by the characteristics of the structure, the mechanical system of the moment of inertia is very large, as there is a low frequency of the torque sensor measurable signal frequency is low.

        In dynamic and accurate measurement, the characteristics of the signal (stable, transient, random, etc.) should be based on the characteristics of the reply to prevent the error that leads to too much.
