Force measurement in linear drives

At present, a transformation is taking place, with linear drives taking the place of pneumatic and hydraulic drives. Here, there is absolutely no longer any scope for measuring pressure. However, WIKA has another solution: Force measurement.
Hydraulic or pneumatic cylinders are increasingly being replaced by electrical propulsion technology. For this, however, it’s important to implement force measurement using force transducers/force sensors. Force measurement through pressure measurement in a hydraulic unit or pneumatics isn’t possible. A typical example for this is linear drives.
Bottom Line : the original situation
A linear drive is really a drive system leading to a translational movement. Machine elements or system parts are accelerated in a straight line. It seems sensible to offer force measurement in such drives, since a transformational change is currently happening: Hydraulically and pneumatically powered drive elements are getting replaced with a combination of electric motor and mechanical thrust units. These modern drive systems are kept simple via modular systems but can, nevertheless, be adapted to individual customer applications with little effort. They also feature a higher level of versatility. However, pressure measurement is not any longer possible here.
Force measurement: advantages
This change offers the perfect opportunity to measure forces directly in the process. Force measurement can be utilized with practically any linear drive. For the complete measurement of the forces, it doesn?t matter where within the force flow the force transducer is integrated. This could be directly on the motor, on the actuator or at the idea of force application. Force could be identified reliably at any point in the force flow.
The F2301 force transducers are ideal for force measurement in linear drives
Force measurement: WIKA products in application
For force measurement, thin-film sensors from WIKA?s volume production are employed, which are welded onto the measuring tubes of the force transducers. This is also one of the reasons why tecsis, because the force measurement specialist within the group, is renowned for innovative quality solutions in metrology and sensor technology. With the different force transducer solutions, from the typical to the miniature tension and compression force transducers, the optimum solution can be found for every application. This might involve controlling joining forces on electrically powered spindle presses, or monitoring the overload protection in lifting cylinders. The robotic arms of gripping and clamping robots along with punches, presses and welding tongs can be measured. With the successful application for the EU ?Clean Sky 2? project, the sensors also meet up with the extremely high safety requirements of the aviation industry.
