Bulksafe WIAS Benefits Water ingress alarm for cargo holds which is insensitive to product type or build – up. Constant self-checking of detection sensors and ‘live zero’ alarm signal confirms system operational health. Simple menu driven/push button operation with full functional checks available at any time from the bridge (holds empty or filled.) |

‘Bulksafe’
water Ingress
detection monitoring & alarm system (WIAS) draws upon almost 30 years
of PSM’s experience in supplying monitoring and alarm systems in
shipboard liquid levels to provide a robust, reliable, simple to install
and operate solution for this critical water ingress detection in cargo application for bulk carrier
safety.![]()
Bulksafe
water ingress sensors are solid state devices with no float or
other mechanisms to fail, or in-built filters requiring regular
cleaning, they provide a 4-20mA
2 wire output which gives 4mA when the cargo hold is dry.
This ‘live zero’ signal provides an immediate indication of
sensor health, a feature not available to simple switch devices. Any
water ingress beyond the permissible limits which is detected while the tanker is underway will
immediately cause this output signal to rise triggering an alarm
condition.
PSM
Bulksafe
systems require only one sensor per hold to
detect both pre and main alarm conditions, sensor and system
operation may be checked at any time irrespective of hold status by
using a simple test
mechanism built into the deck
termination enclosure. No additional compressed air or water services
are needed to effect this test. Installation
/ retrofit is simple, the sensor is supplied with the required
length of cable and simply mounts within a shipyard supplied pipe,
clamped to the inside of the tank. Where holds have a lower stool
and or a keel duct alternative installations are possible PSM
provide a full range of support fittings and tank penetrations to
suit any requirement, and will be happy to supply suggested
installation drawings. Simplicity of operation is a key feature. The user is guided by a full menu structure and all messages and prompts are provided in plain English on a backlit LCD display. Dedicated visual annunciations provide immediate identification of ‘all clear’, “Alarm, active”, “system fault” and “power-fail” conditions.
Water ingress detection
in cargo alarm conditions also trigger an internal
relay which may be used to drive external remote mounted audible and
visual annunciations. If required repeater displays are available for
remote locations These communicate with the primary display via a 2 wire
RS485 serial link and provides an overview of the entire system status.
This remote display can also be used to acknowledge alarm conditions.
Multiple remote displays can be connected if required.
Each
4-20mA loop is protected using a Zener Barrier.
