We have two available Pneumatic Monitoring System options, each with different compliance standards.
• Suitable for most operating environments
• Waterproof & dustproof
The system works by pumping pressurized air between the cuff of the BFM® blue band connector and the spigot.
Air-line sensors immediately detect if this outward pressure is released as the connector cuff begins to get pushed inwards anywhere around the connector when it is being removed, setting off an alarm and/or shutting off any moving parts below.
The control system can be arranged for multiple connectors to aid in monitoring larger installations.
Counters visibly show when the seal is not correct and the system can also be used as a positional sensor to ensure all connectors in a large plant are installed correctly at all times.
To install the system, a small hole (no larger than 3mm (7/64") in diameter) needs to be drilled in between the two ridges of each spigot. The spigot adaptors are then welded on and the system can be screwed in place and wired up to the appropriate control room system (Note: you will need to supply wiring and additional air-line & t-junctions as required).

Testing: We have tested a single Pneumatic Monitoring System on spigots up to Ø350mm. For spigots Ø400mm and over, we advise installing additional sensors. Please contact us for specific recommendations on this.
