Smith Flow Control’s SmartTrap+, is a product which incorporates signals from sensors into a pigging interlocking logic sequence. For operators needing to ensure higher levels of process safety, the SmartTrap+ is an ideal solution.

By incorporating traditional mechanical key interlocking with process sensor information, this ensures all vessels are safe to access and helps to reduce accidents and downtime.

SmartTrap+ incorporates permissive signals and a door lock proximity switch (4-20mA) as standard. The signals can include (but are not limited to) pressure, flow and level detection, as well as the ability to connect to an online pig signaler to confirm pig launched / received signals.
