Kistler introduces strain sensor

Kistler Instruments has unveiled the Type 9234A strain sensor, for use on manual and automatic machine tools ranging from mechanical presses to riveting, clinching and spot welding equipment.

Fixed to the machine frame by a single M6 screw, the sensor is easy to install and use, and measures dynamic and quasi-static stresses indirectly.

The 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 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, to prevent overload damage, monitor riveting, clinching and resistance spot welding processes, for quality assurance and detection of tool breakage or collision in a wide variety of machine tools.

In addition, the sensor is suitable for use in research and development applications requiring ease of installation and precision combined with versatility and reliability.
