In our daily life, we may encounter various types of sensors, among which torque sensors are one of the more common types. However, for many non-professionals, they may not know much about torque sensors, so they will have many questions. Today, we will answer some common questions about torque sensors for you.

Question 1: What is a torque sensor?

A torque sensor is a device that can measure torque. It is usually composed of an elastic body, a strain gauge, a measuring circuit and other parts. In a mechanical system, a torque sensor can be used to measure the torque of a rotating shaft, thereby helping people understand the operating status and performance of the mechanical system.

Question 2: What is the working principle of a torque sensor?

The working principle of a torque sensor is mainly based on the bridge principle of a strain gauge. When an elastic body is subjected to torque, the strain gauge on it will deform, causing the resistance value to change, thereby causing a change in the output voltage of the bridge. By measuring the change in this voltage, the magnitude of the torque can be inferred.

Question 3: What are the application scenarios of torque sensors?

Torque sensors are widely used in many fields, such as in the automotive, aviation, energy, chemical, textile and other industries. It can be used to monitor the torque of the engine, the braking torque of the brake, the torque of the drive shaft, and so on. At the same time, in small devices such as electric bicycles and power tools, torque sensors can also be used to measure and control the working status of the system.

Question 4: How to choose a suitable torque sensor?

Choosing a suitable torque sensor requires considering many factors, such as measurement range, accuracy, stability, environmental conditions, and so on. Generally speaking, it is necessary to select suitable models and specifications based on actual needs and budget. At the same time, factors such as installation and ease of use also need to be considered.

Question 5: How to use and maintain the torque sensor correctly?

Correct use and maintenance of the torque sensor is an important prerequisite for ensuring its measurement accuracy and stability. First, during installation and use, avoid the impact of mechanical collision and strong vibration on the sensor; second, it is necessary to regularly check whether the electrical and mechanical connections of the sensor are normal; finally, avoid exceeding the maximum measurement range of the sensor during use.
