SI-LAS Series_SI-LAS-HL: High Level Alarm System, SI-LAS-OF: Overfill Alarm System, SI-LAS-HO: High Level & Overfill Alarm System

Product Description

The system consists of Local Sensor, Main Alarm Panel, Horn & Rotating Light and I.S. circuit Safety Barrier (in case utilized in hazardous areas). When the magnetic float moves upward to the alarm level, the hermetically sealed magnetic reed switch within the stem will be opened and will initiates an alarm. When the magnetic float moves down to the range of normal condition, the reed switch will be closed (non-alarm position) and alarm will be deactivated., 1. Local Sensor of High Level Alarm System (SI-RS-HL) or Overfill Alarm System (SI-RS-OF): This system generates signals if the level of cargo reaches 95% (HIGH LEVEL ALARM) or 98%(OVERFILL ALARM) of a tank capacity by being installed at the upper part of a cargo tank., 2. Local sensor of High Level & Overfill Alarm System (SI-RS-H0): This system is installed at the top of the cargo tank, and if the capacity of the tank goes up to 95% then the alarm makes a warning. And if the High level alarm reaches to 98%, then Overfill alarm makes a warning., 3. Alarm Unit for Remote High Level and Overfill Alarm Monitoring: It provides visible and audible alarm by receiving high level alarm or overfill alarm signals from a local sensor., 3. Horn & Rotating Light: A device generating alarm lamp and alarm signal with supplying level alarm signal of cargo tanks., 4. Safety Barrier: For a local sensor installed in a hazardous area,
