WBS Type Pump Room Temp. Monitoring And Alarm Device
Product Description
WBS Type Pump Room Temp. Monitoring And Alarm Device
Product Introduction:
This device has been specially designed, manufactured in conformity with 2000 SOLAS Amendment, Chap.Ⅱ-2, Reg.4 amended for protecting the cargo pump room. It has the functions of temp. monitoring, display, alarm and control etc. It is mainly used to monitor and alarm the working temp. of pump room equipments for all kinds of cargo carriers.
Operating Principle:
This device consists of Pt100 type temperature sensors, junction boxes, safety barriers and LED display & alarm panel etc. The device is intended for monitoring the temperature values measured from any number of temperature sensors installed on the each pump. The electrical sensor signals measured from Pt100 temperature sensors are connected to the “pump room temperature monitoring and alarm panel” which provided with temperature display & alarm unit, power supply and power fail alarm as well as high temperature alarm via safety barriers if required. The signals measured from Pt100 temperature sensors are indicated to LED display on the temperature display & alarm unit continuously and the high temperature alarm can be also provided on that unit depending on the configured set-point value.
Features:
*Intrinsically safe design is applicable to all dangerous area.
*Individual adjustable high temp. Alarm for each measuring points.
*Available for any number of measuring points.
*Most advanced electric technology for high reliability and durability.
*Simple construction
*The pumps temperature monitoring and alarm panel gives an audible and visible alarm.
*The individual external alarm can be provided in accordance with customer requirement as optional item
*The bilge level alarm can be provided with this device if required by customer.
Application:
This device is used for continuous monitoring of the temperature values on the bulkhead shaft glands, bearings and pump casings of cargo pumps, ballast pumps and stripping pumps, installed in the cargo pump room and driven by shaft passing through pump room bulkheads.
