Why measure torque?
The industrial challenges
Mechanical torque is involved in countless processes. In bottling, automotive or pharmaceuticals, controlling it is essential to guarantee safety, quality and compliance.
01
Assembly safety
For parts subject to vibration, tightening must be controlled and traceable.
02
Quality and sealing
Capping and bottling: torque guarantees the integrity of the packaging.
03
Regulatory compliance
Standards and metrological traceability for the pharmaceutical and food markets.

Torque measurement in industry: challenges and applications
Mechanical torque is involved in the manufacture of a great many products. Torque measurement is essential wherever a rotational force must be controlled: screwing on a cap, tightening a mechanical assembly, checking tooling, torque testing in R&D. Too little torque leads to leaks or safety defects; too much torque damages parts or makes opening impossible for the end user.
These checks are essential to meet safety, quality and marketing requirements, as well as regulatory ones, particularly in the pharmaceutical and food sectors.
ACRN offers its torque measuring instruments for three main families of applications:
Packaging and bottling industry
The tightening torque of the cap and bottle system must stay within a defined range: neither too low (risk of leakage or contamination) nor too high (risk of difficult opening or damage to the cap). The torque tester is the reference instrument for this check, through random sampling on the production line. It covers all packaging formats: bottles, flasks, cans, screw pumps, tubes. Discover our range of cap torque testers (NBA, SKILLTORK, SKILLTORK+, REPEATORK).
Tool control and industrial tightening
Torque wrenches and torque screwdrivers used for controlled tightening must be checked regularly. Static torque sensors and screwdriver controllers continuously monitor the torque applied on assembly lines.
Tightening of screws and nuts
In the automotive, mechanical and aeronautical sectors, tightening torque is a fundamental safety parameter. ACRN torque testers check starting, breaking and assembly torques with a resolution of one thousandth of a newton-metre.
How is torque measured?
Torque is the rotational force applied to an object. It is expressed in newton-metres (N.m) or pound-feet (lb-ft). Most current measuring devices are electronic and offer a direct digital reading, data export and network connectivity for traceability.
Several technologies exist depending on the use: bench torque testers for manual checks in packaging, motorised torque testers for tests with optimised repeatability, torque wrenches and screwdrivers for controlled tightening, and static sensors mounted under the screwdriver for in-line production control.
How to choose your torque measurement method?
The choice depends on several parameters: the torque range to be measured (in N.m), the shape of the samples to be held, the test frequency, the need for traceability and the desired level of automation. ACRN supports its customers from needs analysis to implementation: choice of sensor, torque range and gripping accessories, and integration into the existing quality system. Our equipment is designed to be robust, upgradable and repairable, with the longest service life on the market.
Frequently asked questions
FAQ: torque measurement
What is torque measurement?
Torque is the rotational effort applied around an axis: a force multiplied by the length of the lever arm. Measuring torque means checking that a cap, a screw or an assembly is tightened, or opens, within the range set by the specifications.
Torque tester or torque meter: what is the difference?
None: both words refer to the same instrument, the torque tester (also called torque meter). It measures the torque applied to a sample. A torque wrench, on the other hand, is used to apply a defined tightening torque.
How do you measure rotational torque?
The sample (bottle, cap, screw) is held in the torque tester, then the rotation is applied by hand on a bench torque tester, or by a motor on a motorised torque tester for better repeatability. The device displays the measured torque: opening torque (starting, breaking) or tightening torque.
What unit is torque expressed in?
Torque is expressed in newton-metres (N.m), or in sub-multiples such as cN.m for low torques. In English-speaking countries, pound-feet (lb-ft) and pound-inches (lb-in) are also used.
Should a torque tester or torque wrench be calibrated?
Yes: to guarantee reliable and traceable measurements, torque measuring instruments must be checked regularly. ACRN calibrates them in its laboratory or on site, with COFRAC metrological traceability.
