The explosion-proofing mechanical passage indicator is designed and developed on the basis of mechanical passage indicator and its display part adopts cast aluminum alloy housing anti-explosion design to suit explosive operational conditions. It features direct viewing, reliable performance and easy operation, with its display portion deployed with built-in monolithic computer, LC digital display, intelligent control to allow normal time and passage time indicators. It is possible to furnish a transient switching signal of the pipeline cleaner passage time remote transmission.
