The strain sensors are said to be easier to fit, simpler to replace, more reliable and longer lasting than the load cells previously used.

With experience spread over 80 years and an impressive worldwide customer list, which includes most of the leading automobile and aerospace companies, Slough-based

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.

In addition to fitting the sensors to new welding machines, Sciaky now retrofits the Kistler strain sensor whenever the old-style load cell needs replacing. According to Sciaky MD, Louis Kunzig, the strain sensor is now fitted as standard to all Sciaky Resistance welding machines supplied for aerospace applications and for critical applications, such as manufacturing steering components, in the automobile industry.
