The Process Controller STF-1 Expert is a further development of the Process Controller
STF-1 Super Plus and offers following additional advantages.

Auto-Compensation

Auto-Compensation of the riveting parameters S or T dependent on the rivet protrusion

This function produces a proportional increase / decrease of the parameters S or T by a defined percentage ratio of the deviation from U. This function makes riveted modules considerably more tolerant to errors. For the user, this means the allowance of larger dimensional tolerances and thereby a more cost-effective manufacturing process for rivets.

The Auto-Compensation requires a mechanical sensing organ on the riveting spindle that detects the base of the workpiece. Using this measuring unit, derived from a rivet stroke limit switch unit which a patent was applied for in 1996 and which has been developed further in the meantime, unforeseen possibilities become available to you.

Stroke-end-stop-equipment (NHE)

The innovation here is that not only the protrusion of the rivet, but all process data can be recorded and evaluated. The operation and the comprehensibility have nevertheless been further improved. This model and its range of functions set new standards.

This additional function makes the optimised utilisation of the Process Controller STF-1 Expert with a master PLC possible without the RC-20A.
