Signaling device SLL

Automated processes use intelligent signalling systems to keep you informed at all times about the status of your entire plant and any faults that may arise. You can even install signalling devices for rupture discs that have already been installed. To evaluate the signals, we offer you an isolating switching amplifier with a relay output, which ensures an intrinsically safe quiescent circuit. The potential-free relay contact is used for safe system shutdown or alarming. These hit the reflector on a rupture disc and are registered by the SLL receiver. Both the transmitter and receiver are integrated in the SLL sensor head. When the rupture disc opens, the reflection is broken and a signal is transmitted from the SLL receiver to the connected process control system.
