Position monitoring system for marine loading arm
PMS
EMCO WHEATON
Our Position Monitoring System (PMS) is used to display the position of the marine loading arm within its defined operating envelope. The display uses a standard industry PC and is a live feed of the actual position of the marine loading arm.
The PMS is a stand alone unit and works in the following way:
* 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.
* Information from the potentiometers is relayed through a PC hooked to the local control panel
