Five reasons for force measurement

May 2022 Editor's Choice Maintenance, Test & Measurement, Calibration

Wika has been an internationally-recognised partner for all measurement tasks for many decades. The company’s product portfolio includes pressure, temperature, force and level measurement, as well as flow measurement, calibration and SF6 gas solutions.

In the following article, the company takes a closer look at the measured variable of force. These five reasons show why force measurement is of particular importance.

Reason 1: Protection of people and machinery

Protecting people from harm is the highest priority in any workplace. Likewise, the machinery should remain undamaged in order to minimise downtime and repairs. In this context, force measurement ensures a safe working environment, especially through overload protection. In cranes, for example, this prevents heavy loads from falling. With construction machinery and robots, on the other hand, uncontrolled machine movements are prevented. This makes it possible to work safely and completely harmlessly next to and with machinery. In production lines, the machinery is prevented from pulling, pushing or pressing unchecked, which could result in destroying both components and itself. Another example is port logistics, for which Wika offers a globally unique, certified system.

Added value: A safe working environment.

Reason 2: When ensuring system stability and production safety, just collecting data is not enough

The correct measured values are also required to be able to monitor processes seamlessly. Using force measurement in linear drives, for example, improves process control as well as automation, while simultaneously ensuring quality. Force measurement also provides the right data for the correct functioning of brakes and drives, conveyors, presses and weighing systems. A crucial point here is to reduce running costs. The higher the quality of the measured data, the better the data analysis. The planning of a tool change is thus more precise, so that changing it too early does not cause increased costs In addition, unplanned maintenance will no longer cause longer downtimes. The savings in consequential costs alone pay for it many times over.

Added value: Full process control.

Reason 3: Optimisation of production conditions

The savings potential, and thus the maximisation of profit, have already been mentioned in the previous section. Only through the optimal use of materials and machinery can margins be increased. A key issue in manufacturing plants is machine availability. In addition to reducing downtime, the focus is on minimising maintenance costs. A good example of this is welding tongs. Here the contact force of the electrodes can be precisely monitored by using tension/compression force transducers. In this way, optimum quality is permanently guaranteed, and at the same time wear is minimised. Higher profits can also be achieved through saving time, for example, when containers are weighed ‘on the fly’.

Added value: Maximum profits.

Reason 4: Improving product quality and saving materials

The use of force measurement in welding tongs – as explained in the section above – is a very good example of improving product quality as well as saving materials. Force measurement provides the right data for the most accurate process control. As a result, machine tool wear is only minimal. In addition, force measurement offers many other areas of application. For example, spreading fertiliser where this action is adapted to the soil conditions is one way to save material. This also protects the environment. Furthermore, it is advantageous to know the supporting forces acting on mobile cranes. The vehicle’s centre of gravity can thus be precisely calculated, which means that the safety margin can be reduced. In this case, loads can be lifted further, while accidents due to slipping or tipping can be avoided.

Added value: Lowering costs.

Reason 5: Ensuring quality

Finally, the use of force measurement also offers many advantages in the area of quality assurance, which has already been touched upon. On the one hand, the machinery can be optimally controlled by registering the force. On the other hand, by recording the values, live as well as saving them for later use, conclusions can be drawn for specific batches. In addition, the most precise force measuring instruments meet the highest requirements, for example, in materials testing machinery or in medical engineering. Wika also offers a DAkkS-accredited calibration service for force measuring instruments.

Added value: Exact measured values.
