Explosion-proof Overflow Overfill Static Grounding Control System – Road Tanker Depot

Used to monitor and protect in petroleum and chemical plants, petrol stations, oil depots and tanker assembly and disassembly depots etc.  Provides overflow static protection and quantitative loading system interlocking control. Avoid overflow accidents and ensure safe static grounding

Performance Features

◆ The controller enclosure is flameproof type, reliable explosion-proof performance.

◆ Static grounding clamp has tank car identification function, ensure its installed on tank car correctly, not other electric conductor, with no-spark type grounding clamp, no spark produced when equipment impact.

◆ Static grounding clamp has resistance inspection and liquid level monitoring function, provide local and remote audible and visual alarm and interlocking signal for “static” and ”overflow status”, which is convenient for operator to find out problem and avoid overflow accident.

◆ Grounding body resistance has inspection function, ensure reliable grounding of system, when electrostatic grounding is bad or grounding loop resistance >10Ω, provide alarm warning.

◆ With voice and LCD function, the intensity of the sound is 70~120db (the distance is 30cm).

◆ Relay signal output for DCS pump (valve), when grounding is not normal, cut off the operation, audible and visual alarm can still be remote controlled, remind operator the real-time status of on-site grounding.

◆ Red LED shows warning, green LED shows normal working, yellow LED shows standby status.

◆ Grounding clamp uses alloy aiding thimble, with the features of high hardness, good electric conduction, strong breaking paint and rust power, etc. ensure good grounding monitoring device.

◆ Grounding clamp is helix tube shrink design, with the capacities of strength anti-pull, anti-drop, etc.

◆ It can intelligently detect whether the human static voltage is conducted, when the human static voltage is in a dangerous value,sound and light alarm.
