Marine control instrumentation specialist PSM has developed a new marine certified monitoring system based on its existing VPM central monitors, with an enhanced processing unit capable of receiving input from multiple signal sources.
Scanjet PSM's popular VPM (which stands for Versatile Process Monitor) system comprises a modular and flexible family of tank monitoring and flood detection systems which can be tailored for all ship sizes, ranging from smaller vessels such as tugs workboats and yachts through to larger vessels including tankers, where the system requires a considerable number of input points, and a more comprehensive display is required.
The latest generation Connect system processor can be connected directly via RS485 communication to Scanjet PSM's APT1000 intelligent tank level and pressure transmitters, or via intelligent interface cards which incorporate Intrinsic safety barriers and accept signals from any 4-20mA instrument.
Further interface cards allow connection via HART protocol to Scanjet PSM's Marine approved Radar level transmitters for Cargo tank monitoring.
All signal processing and data calculations are undertaken within the Connect central processing unit, with multiple input ports offering the scope for limitless expandability. Tank tables, trim and heel correction, specific gravity, overpressure, temperature, and all other related parameters are considered to provide accurate real-time display of tank status.
Both local and remote displays are interfaced to the central processing unit via ethernet connection. In effect, the central processing unit acts as a server and the displays as clients, and any display hardware which can run an internet browser may be used to view data. A diverse range of display monitors are available, each with a small processing hub, which allows ethernet communications to be managed without the need for a costly computer at each location.
Information from the Connect system can be displayed in multiple formats, dependent on which is most suited to individual applications, such as tabular, bar graph, tank plan and hybrid views. Tanks may also be grouped with dedicated alarm pages showing warnings and status at all times.
Since connection is by means of IP address it is also possible to remotely connect to the system via internet, either for display of information at a remote location, or for making changes to configuration.
A hierarchy of password protection ensures data can be viewed / amended only by personnel authorised to do so.
Suitable for all tank gauging applications, the new Connect system is Type approved by DNV and also MED certified for use on passenger vessels for flood detection monitoring purposes.
Since the release of the Connect system, Scanjet PSM has already secured a number of orders for applications as diverse as fishing vessels, naval oil tankers and a land-based tank farm, underlining Connect's versatility as a scalable monitoring solution.
