LBC/pneumatic

Pneumatic line break detection system.

The Fahlke pneumatic LBC offers the user immediate detection of any pipeline fluctuations and allows the fluctuation to be secured immediately in order to automatically prevent continued egress of the line medium.

The Fahlke pneumatic LBC permanently measures a predefined pressure loss rate using the connecting line coming from the pipeline. This provides continuous pipeline monitoring and, when the predefined pressure loss per minute is reached, all connected actuators/valves are switched to their emergency/safety position.

The Fahlke pneumatic LBC can either be integrated directly in the Fahlke MCE control or – as shown here – can be built into a separate control cabinet.

Adjustment range: 0.5 – 2.5 bar/min. (higher values available on request)
Medium: Air, gas
Temperature range: -25 - +70°C (low temperature versions available on request)
Dimensions: approx. 350 x 150 x 150 mm
Mini metering connections: 2

LBC/P designed and integrated into the Fahlke MCE controller technology in modular construction.
