Monitoring tool loading on machine tools and assembly machines is essential for quality control and prevention of overload damage; the Type 9234A self-contained strain sensor from Kistler Instruments can be used on a wide range of manual and automatic machine tools, from mechanical presses to riveting, clinching and spot-welding equipment. Fixed to the machine frame by a single M6 screw, the sensor is claimed to be exceptionally easy to install and use for measuring both dynamic and quasi-static stresses indirectly.
A built-in charge amplifier with remote range switching provides an industry-standard analogue +/-10V output and the range can be changed from a dedicated remote control or directly by the machine PLC. Each of two measuring ranges can be adjusted to a specific value or signal curve in 100 steps. The signal can be displayed locally and remotely and used to stop the process via the machine PLC when an out-of-range load or a potentially damaging overload is detected. When required, the output signal can be processed as a relative value or calibrated against an appropriate standard to provide absolute measurements in N or kN.
Mounted on a clean, unpainted area of the machine frame, the sensor can monitor C-frame machine tools, such as presses and automatic assembly machines, for various tasks:
In addition, the sensor is suitable for use in research and development applications requiring ease of installation and precision combined with versatility and reliability.
