At pressure gauge , a transformation is occurring, with linear drives taking the area 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 is necessary to implement force measurement using force transducers/force sensors. Force measurement through pressure measurement in a hydraulic unit or pneumatics is not possible. A typical example because of this is linear drives.
Force measurement: the initial situation
A linear drive is a drive system leading to a translational movement. Machine elements or system parts are accelerated in a straight line. It seems sensible to provide force measurement in such drives, since a transformational change is currently happening: Hydraulically and pneumatically powered drive elements are receiving 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: the advantages
This change supplies 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 on the motor, on the actuator or at the point 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. That is also among the reasons why tecsis, as the force measurement specialist within the group, is renowned for innovative quality solutions in metrology and sensor technology. With the various force transducer solutions, from the standard 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 and punches, presses and welding tongs can even 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.
