Leuze electronic has come up with a novel process called Smart Process Gating (SPG) that it reckons makes it more economical, simpler and safer to implement muting processes.
When safety sensors such as light curtains are used to detect unauthorised intrusions in applications such as intralogistics, automotive manufacturing and the packaging industry, a muting process is required to allow legitimately transported goods through the barrier.
Traditionally, this has required the use of additional muting sensors. But in the SPG system, the additional sensors are not required.
With SPG, the first muting signal comes from the process control system, and the second muting signal is generated by the protective field itself. Smart Process Gating requires a detailed knowledge of the process so that the necessary SPS control signals are made available in the expected time window.
As a result, conveyor systems based on Leuze electronic MLC safety light curtains can be made more compact. The risk of misalignment or damage to the sensors is eliminated as are the costs for their maintenance and servicing.
