Actuators with built-in wireless sensors help improve machine productivity

Ewellix, formerly SKF Motion Technologies, has redesigned its high performance CASM-100 and LEMC actuators with built-in wireless sensors that can detect force and temperature.
According to the company, it has developed the new actuators, which deliver forces up to 82kN and speeds of 1m per second, to provide real-time, accurate information that improves machine productivity. These feature integrated force sensors within the body of the actuator to provide a precise measurement of the torque being delivered from the motor through the internal ball or rollerscrew, even when the actuator is stationary. In addition, the sensor acts as a temperature monitoring device that activates an alarm if the actuator is at risk of overheating.
This configuration provides operational information in real-time, which can be communicated to higher level control systems. As a result, the company explains, it is possible to improve overall performance and productivity, with greater safety.
Both types of actuators are available in multiple combinations covering a wide range of applications. The built-in sensor enables measurements to highlight how space and energy savings can be achieved through downsizing attachments.
This leads to an overall cost reduction of the production line, while still delivering safer manufacturing processes. A further advantage of having the Ewellix IoT-ready actuators with sensors is that when converting from a hydraulic system to an electro-mechanical one, it is easier to specify the correct sized actuator for the job, the company explains.
