Proposed System Configuration

Wireless vibration sensors are installed at locations where pump and motor

vibration can be measured. The measured vibration values are aggregated

into the Wide Area Monitoring System, and the AI (State Change Detection Service)

 learns the vibration values under normal conditions and creates a model.

Whenever there is a change in the vibration values of pumps and motors that

deviates from the normal state, the AI model detects the change. This enables

early detection of changes in the condition of pumps and motors, leading to 

replacement of parts before they fail. By applying this system to cooling water

pumps in various locations in the plant, it is possible to monitor all cooling water

pumps at once to see which ones are showing abnormalities. 

Furthermore, the Wide Area Monitoring System is scalable to enable combined

monitoring of cooling water temperature and pressure, as well as equipment data,

allowing for flexible proposals tailored to each case.

Easy to start using! Wide Area Monitoring System solves 

remote monitoring issues

Facilities that exist in a wide area can be integrated and managed

through remote monitoring.

The cloud can be used to reduce time and costs, and to

efficiently build monitoring systems.

Value through problem solving

By capturing changes in the condition of cooling water pumps and motors

with vibration sensors, cooling water pump parts can be replaced before

failure occurs. This prevents cooling water pump failure and damage to the

equipment to be cooled.

Detecting the signs of cooling water pump failure

in various places in the plant

▲ Cooling water pumps are used in various

places in the plant.

Deterioration of the rotating equipment and

other components that make up the cooling

water pumps can lead to failure of the pumps.

Furthermore, if the cooling water pumps fail

and the cooling water temperature cannot be

maintained, the equipment that needs to be

cooled may also be damaged.

▲ Cooling water pumps are located in various

places in the plant, which require many

man-hours to inspect.

For Safe Use of Product

For the protection and safety of the operator and the

instrument or the system including the instrument, please

be sure to follow the instructions on safety described

in this manual when handling this instrument. In case

the instrument is handled in contradiction to these

instructions, Yokogawa does not guarantee safety.

Please give your attention to the followings.

(a) Installation

• The instrument must be installed by an expert

engineer or a skilled personnel. The procedures

described about INSTALLATION are not permitted for

operators.

• In case of high process temperature, care should

be taken not to burn yourself because the surface of

body and case reaches a high temperature.

• The instrument installed in the process is under

pressure. Never loosen the process connector bolts

to avoid the dangerous spouting of process fl uid.

• During draining condensate from the pressure

detector section, take appropriate care to avoid

contact with the skin, eyes or body, or inhalation of

vapors, if the accumulated process fl uid may be toxic

or otherwise harmful.

• When removing the instrument from hazardous

processes, avoid contact with the fl uid and the interior

of the meter.

• All installation shall comply with local installation

requirement and local electrical code.

(b) Wiring

• The instrument must be installed by an expert

engineer or a skilled personnel. The procedures

described about WIRING are not permitted for

operators.

• Please confi rm that voltages between the power

supply and the instrument before connecting the

power cables and that the cables are not powered

before connecting.

(c) Operation

• Wait 10 min. after power is turned off, before opening

the covers.

(d) Maintenance

• Please do not carry out except being written to

maintenance descriptions. When these procedures

are needed, please contact nearest YOKOGAWA

offi ce.

• Care should be taken to prevent the build up of drift,

dust or other material on the display glass and name

plate. In case of its maintenance, soft and dry cloth is

used.

(e) Explosion Protected Type Instrument

• Users of explosion proof instruments should refer fi rst

to section 2.4 (Installation of an Explosion Protected

Instrument) of this manual.
