Why Do Linear Drives Require Force Measurement?

Force Measurement

Many industrial processes are switching to linear drives as opposed to pneumatic and hydraulic drives. With this change, it is becoming harder and harder to measure pressure. However, there are alternatives that give machine operators hope. Force measurement is now increasingly relying on force transducers and sensors to measure force. This is because it is impossible to use pressure measurements to take force measurements in a pneumatic unit. First, however, let us understand the basics.

What is a Linear Drive?

A linear drive is a system that creates translational movements. In such a system, the machine elements are driven in a straight line. Linear drives are simple as they use modular systems but can be adapted to fit the needs of the client. They also have the additional advantage of being very versatile.

Understanding Force Measurement

Force is any interaction that changes the direction that an object us taking on condition that is process is not opposed. Objects that have mass can have their velocity changed including objects that were at rest. There are two main ways force is applied namely as a push or as a pull force. One feature of force is that it also has a magnitude.  This refers to how much force is applied to the object. It also has a direction and thus a vector unit.

Why Force Measurement?

Having linear drives offers the opportunity to measure forces directly during the process. Whether the transducer is linked to force flow makes no difference. The transducer can be on the actuator, the motor or even at the point where the force is applied. The reliability of the tests will still be highly accurate. Force measurement is critical in all sorts of applications. From machinery that produce our consumer goods to some of the products, we use ourselves. A good example of force measurement in everyday products is when it comes to springs. These are used in a variety of products including ball pens, automobiles and much more. The ability of these products to work well is dependent on how well force is applied by the springs that are in the product. Quality control experts must carefully measure the force that is released by the springs as it determines the functionality of the products.

Real-Life Applications for Linear Drives

Linear drives are found in a variety of applications. These range from material handling, as well as robotics. They are also found in food and beverage industries as well as agricultural machinery. Manufacturing facilities, especially those that utilize heavy-duty ventilation systems use electric linear actuators to open and close the heavy ventilation systems. Solar farms that have hundreds of large solar panels also utilize linear actuators to tilt the panels. This, in turn, allows for the panels to get maximum exposure to the sun. Without the ability to measure how much force these systems are putting out; it would be very hard for their operators to monitor their performance.
