Torque measurement

What is a torquemeter ?

A torquemeter is a highly precise instrument used to measure torque. Torque refers to the rotational force applied to an object, measured in Newton-meters (Nm) or foot-pounds (lb-ft). It is often used to describe the rotational capacity of a motor or gear system. How torque is measured varies, with devices ranging from analog to electronic, though most are now electronic.

What other names are used for torquemeter ?

This measuring system may also be called: Table torquemeter, torquemeter or bottle torquemeter.

In which sectors are they used?

Torquemeters are primarily used in the packaging industry. For instance, during bottling, the applied torque on the bottle-cap system must be carefully adjusted. If the torque is too low, there’s a risk of leakage or contamination, and if it’s too high, it could lead to difficulty in opening or damage to the cap. Torquemeters allow for precise measurements of torque in various applications, such as:

• Cosmetics: Used for perfume bottles with screw-on pumps (perfumes, creams, lotions, etc.).
• Food industry: Applied to milk, soda, mineral water bottles, or any container sealed with a cap, including tamper-evident ones.
• Pharmaceutical industry: In products like medication bottles sealed with safety caps or child-resistant closures (CRC).
• Wine industry: Used by wineries for measuring torque on wine bottles with screw caps, particularly suited for mobile bottling control.
• Chemistry: For testing closures on containers (e.g., oil cans or pesticide bottles) and electronic cigarette refills.
• Manufacturers of packaging materials (plastic, glass, wood): Used in quality control for items like bottles, caps, and pumps.

In various industrial sectors, how torque is measured plays a critical role in applications such as:

• Controlling the torque on torque wrenches or torque screwdrivers for tightening tasks.
• Testing rotational components like lipstick mechanisms or automotive parts (e.g., windshield wipers, drawers, or armrests).
• Assessing the torsion of components in mechanical systems.

What are the advantages of ACRN torquemeters?

In various sectors, torque measurement needs differ greatly. By working with our industry experts, we will assess all your challenges. We analyze your product variety and shapes to propose interchangeable and quick tightening systems. We select the right torque range for the sensor and ensure precision. We also provide best practices on how to measure torque consistently, and advise on accessory use to ensure accurate torque measurements.

Our equipment is durable, upgradeable, and repairable, offering the longest lifespan on the market.

In recent years, we’ve carried out several projects to integrate torquemeters into quality control processes to support the digitalization of factory quality control (traceability, data integrity). Our equipment and experts are ready to meet your needs for measuring torque.

How does a torquemeter work ?

The principle of a torquemeter is to measure the unscrewing torque of bottles, flasks and samples taken at random from the production line.

For the values to be respected, there are torque measurement charts that depend on the cap and diameter. We can provide you with the usual torque measurement specifications to help you acquire the right equipment.

Is the torque test easy to deploy?

This test is widely used in the food, cosmetics and pharmaceutical industries, as well as by screw and spirits manufacturers/packagers. It’s easy for operators to use and inexpensive to deploy.

What else does a torquemeter do ?

These torque testers are also used to test torque wrenches and other types of tooling. Please contact us if you’d like to set up a torque wrench test with a standard torquemeter, and we’ll be happy to set up a typical setting taking into account your measurement range and other parameters.
