FAQ

A shaft torque sensor is a device that measures the torque on a rotating system like a motor, crankshaft, or gear. It provides real-time, highly accurate measurements, which are crucial for monitoring and control applications.

Torque on a shaft can be measured using a shaft torque sensor. These sensors are installed directly on the rotating shaft, where they detect and measure the torsional strain (twisting) on the shaft as it rotates under load.

In cars, a torque sensor is typically used to measure engine output torque. This information can be used to optimize engine performance, enhance fuel efficiency, and inform decisions on safety systems.

The two main types of torque sensors are static torque sensors and dynamic torque sensors. Static torque sensors measure torque without rotation (static conditions), while dynamic torque sensors measure torque during rotation.

What Is a Torque Transducer? How to Choose?

Posted on February 26, 2023 by KimGuo11

Torque transducers are essential tools in many industries that rely on precise measurements of rotational forces. These devices play a crucial role in measuring the torque produced by engines, motors, and other rotating systems.
Whether you’re working in the automotive, aerospace, or manufacturing industry, understanding what a torque transducer is and how to choose the right one is crucial for optimizing performance and ensuring accuracy.
In this blog post, we’ll explore everything you need to know about torque transducers, including their types, applications, and factors to consider when selecting one for your specific needs.

What is torque?

Torque is a term used to describe the twisting or rotational force applied to an object. You can think of it as the force that causes an object to rotate around a fixed axis, like a wheel turning on an axle.

Torque is measured in units of force times distance, such as pound-feet or newton-meters.

In everyday life, you might experience torque when tightening a bolt with a wrench or using a crank to turn a wheel.

In the world of engineering and physics, torque plays a critical role in understanding how machines and engines work, and how to measure and optimize their performance.

More about torque definition and calculation.

What Is a Torque Transducer?

A torque transducer is a device that measures the amount of twisting or rotational force (torque) applied to a rotating system.

It’s like a scale for measuring the torque produced by machines and engines.

Torque transducers can be used in a wide range of industries, such as automotive, aerospace, and manufacturing, to optimize performance and ensure accuracy.

There are different types of torque transducers, including strain gauge, magnetoelastic, and optical, which work by different principles to measure torque.

By providing accurate measurements of torque, torque transducers help engineers and technicians understand how machines and engines are performing and make improvements where necessary.

Torque Transducer Measurement Principle

The measurement principle of a torque transducer is all about detecting and measuring the twisting or rotational force applied to a rotating system.

Torque transducers work by using different methods, such as strain gauges, magnetoelasticity, or optical technology, to sense the amount of torque being applied.

For example, strain gauges work by measuring the electrical resistance of a metal strip that changes as it stretches or compresses in response to the applied torque.

The magnetoelastic type, on the other hand, uses a magnet and a magnetic field to sense changes in the shape of a metal element.

In each case, the torque transducer converts the twisting force into a measurable electrical signal, which can be analyzed and used to optimize the performance of the machine or engine.

Types of torque transducers

Type of Torque Transducer	Measurement Principle	Advantages	Disadvantages
Strain Gauge	Uses metal strip to change resistance when twisted	Accurate and cost-effective; Good for low-torque applications	Can be sensitive to temperature changes
Magnetoelastic	Uses magnetic field to measure torque	Highly accurate and durable; Good for high-torque applications	Can be expensive
Optical	Uses light to detect changes in material’s properties	Highly accurate and non-contact; Good for high-speed applications	Can be expensive and sensitive to vibration
Rotary Transformer	Uses two coils and a magnetic field to measure torque	Highly accurate and durable; Good for high-torque applications	Can be expensive and sensitive to temperature changes
Hybrid	Combines two or more principles for more precise measurement	Can offer advantages of multiple types	Can be more complex and expensive

Static / Reaction Torque vs. Rotary Torque

When it comes to measuring torque, there are two main types: static/reaction torque and rotary torque.

Static torque refers to the twisting force applied to a non-moving object, such as a bolt or a nut.

Rotary torque refers to the twisting force applied to a rotating object, such as a motor or an engine.

Static torque measurement is important for applications where a component needs to be tightened to a specific torque value, such as in the automotive or aerospace industry.

Rotary torque measurement, on the other hand, is critical for assessing the performance of rotating machinery and ensuring its efficiency and longevity.

Both static and rotary torque measurement have their own unique challenges and require different types of torque transducers.

Understanding the differences between these two types of torque measurement is essential for selecting the appropriate torque transducer for a specific application.

Stationary Torque Transducer Working principle

The static torque sensor has round shafts at both ends. It is praised by users for its excellent stability, high measurement accuracy, high cost performance and simpler monitoring method.

The measuring elastic body of the sensor does not participate in relative motion. The testing elastic body is subject to relative reaction force. When installing, one end is fixed and the other end is stressed.

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 torsion can be measured by supplying power to the strain bridge.
After the strain signal is amplified, it becomes a frequency signal proportional to the torsional strain through voltage/frequency conversion.
Or directly output standard 4-20mA current signal and 1-5V voltage signal.
