BFM® Pneumatic Monitoring System

Know when your connectors are removed!

Wherever you have a flexible connection in a live production system, if the connector is removed at any time, there is always a potential risk that hands can be placed near dangerous moving parts, such as rotary valves and rotating knives.  

Now you can have added peace of mind that you can monitor when a BFM® fitting is removed in these areas with the latest innovation developed by the team at BFM®: the Pneumatic Monitoring System.

It’s a simple-to-install system that comes in a box!

How Does It Work?

The system works by pumping pressurized air between the cuff of the BFM® blue band connector and the spigot.  

Airline 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.

Please note:  the Pneumatic Monitoring System is designed to be used with BFM®'s Seeflex range of blue band connectors.

How do I install the Pneumatic Monitoring System?

The BFM® Pneumatic Monitoring System comes in a box with the spigot connections, the pressure switches (with t-junctions attached), a regulator and a small amount of airline pipe. 

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 (NB: you'll just need to supply wiring and additional air-line & t-junctions as required). You can download the installation guide here.

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