Strain sensors monitor welding
21 March 2014
Leading manufacturer of resistance welding technology, Sciaky Electric Welding Machines, is using Kistler piezoelectric strain sensors to meet the demands of the aerospace industry for the precise monitoring of the welding process.

The Kistler strain sensors are easier to fit, simpler to replace, more reliable and longer lasting than the load cells previously used.
Unlike a load cell, the piezoelectric strain sensor measures the force at the electrodes indirectly by reference to the strain on the main body of the machine. The conversion from strain to force is achieved using a Kistler Type 5073A single channel industrial charge amplifier which is mounted on the machine remotely from the sensor.
