Lights up when conditions are normal Monitoring (and at incipient liquid leak detection) First stage: Lights up at incipient liquid leak detection Initial detection (non-safety output) (and at abnormal leak detection) Report the occurrence of an incipient liquid leak to the production supervisor Use as a warning and perform equipment maintenance after removing any work in progress. (Initial detection output) Incipient liquid Warning leak PLC, etc. Display Sensor By quickly detecting even small liquid leaks (incipient leaks), personnel can perform preventive maintenance Ensure productivity or plan maintenance, thereby reducing both downtime and damage to work in progress. Second stage: Liquid leak detection (safety-critical output) Lights up at abnormal liquid leak detection Emergency stop Sensor Stop instruction (Liquid leak detection output) Relay, etc. Motor, etc. In the event of a high-volume liquid leak (an abnormal Ensure safety liquid leak), the target equipment is stopped immediately to ensure safety. The SQ4 can also be used alone. The SQ4 can also be used without a controller, allowing the bene ts of two-stage detection to be added to existing equipment by augmenting or replacing existing detection systems.
