Torque Measurement in Industry: Challenges and Applications
The concept of mechanical torque is central to the manufacturing of a wide range of products. Torque measurement is essential in any application where rotational force needs to be controlled: screwing on caps, tightening mechanical assemblies, tool inspection, and torque testing in R&D. Insufficient torque can cause leaks or safety issues; excessive torque can damage parts or make it impossible for the end user to open the device.
These checks are essential for addressing safety, quality, and marketing concerns, as well as regulatory requirements—particularly in the pharmaceutical and food industries.
ACRN offers its torque measurement instruments in three main application categories:
Packaging and Bottling Industry
The tightening torque of the cap-and-bottle system must remain within a specified range: not too low (risk of leakage or contamination), nor too high (risk of difficulty opening or damage to the cap). The torque meter is the standard instrument used for this inspection, which involves random sampling from the production line. It covers all types of packaging: bottles, vials, cans, screw-top pumps, and tubes.
Tool inspection and industrial clamping
Torque wrenches and torque screwdrivers used for controlled tightening must be checked regularly. Static torque sensors and screwdriver controllers enable continuous monitoring of the torque applied on assembly lines.
Tightening screws and nuts
In the automotive, mechanical, and aerospace industries, torque is a fundamental safety parameter. ACRN torque transducers enable the measurement of starting, breakaway, and assembly torques with a resolution of one-thousandth of a Newton-meter.
What is a torque measuring instrument?
A torque measuring instrument—known as a torque meter, torque gauge, or torque sensor, depending on the context—is a precision device that measures the rotational force applied to an object. Torque is measured in newton-meters (N·m) or foot-pounds (lb-ft). Most modern devices are electronic and offer direct digital readouts, data export, and network connectivity for traceability.
There are several types of torque measurement technology, depending on the application: benchtop torque meters for manual testing in packaging, motorized torque meters for tests requiring optimized repeatability, torque wrenches and screwdrivers for controlled tightening, and static sensors integrated into screwdrivers for in-line production monitoring.
How do you choose a torque measuring instrument?
The choice depends on several factors: the torque range to be measured (in N·m), the shape of the samples to be held, the frequency of testing, the need for traceability, and the desired level of automation. ACRN supports its customers from needs analysis through to implementation: selecting the sensor, torque range, and tightening accessories, and integrating the solution into the existing quality system. Our equipment is designed to be durable, scalable, and serviceable, with the longest lifespan on the market.
