Position monitoring

The Position Monitoring System (PMS) displays the position of the marine loading arm within its defined operating envelope. The display is a live feed of the actual position of the marine loading arm. The PMS is a stand-alone unit, uses a standard industry PC and is Excel compatible.

How it works

The Emco Wheaton PMS works according to the following principle.

• a pendulum potentiometer located on the inboard arm measures the angle of the inboard arm with respect to vertical
• a pendulum potentiometer located on the outboard arm measures the angle of the outboard arm with respect to vertical
• a direct coupled potentiometer located at the base riser swivel joint measures the slewing angle.

The information from the potentiometers is relayed through a PC, hooked to the local control panel.
