The day to day
construction
of buildings,
highways, bridges and much of the world’s infrastructure
relies on cement, and the reliability of the plants to
produce this product continuously for world consumption.
From limestone to clinker to cement, there is a never
ending chain of shovels, trucks, crushers, conveyors,
kilns, ball mills, and numerous other pieces of rotating
equipment providing a high quality and long lasting
material for today and tomorrow.
Inside these cement plants the equipment is subjected
to heavy use, dirty environments, and in the case of the
kiln, temperatures that can reach 1500°C. The rotational
equipment of the cement plant utilizes both rolling
element bearings and sleeve bearings as the application
dictates. CM (Condition Monitoring) programs are put in
place to monitor the vibration of the bearings throughout
the plant, and improve the reliability of the overall process.
•4-20 mA Process Monitoring using loop power
sensors will provide operations with the overall
vibration level of the machine so that it can be
trended and alarmed using the in plant DCS, PLC,
or SCADA systems.
•Dynamic Vibration Analysis using
accelerometers will provide detailed information
on the frequency and amplitude of vibrations
generated by the machine.
•A combination of Dynamic Vibration Analysis and
Process Monitoring will provide operations and the
vibration analyst with the tools they need to maintain
daily production quotas.
Process Monitoring will require permanently mounted
loop power sensors like the LP202, LP204, LP252, or
LP254 series that output a 4-20 mA signal proportional
to velocity. A durable cable like CB111 (Yellow Jacketed
Teflon®) or CB206 (Stainless Steel Armored Jacket)
combined with the V2N (CB111 only), B2N, or A2N
connectors over molded on the cables will provide reliable
connectivity back to the PLC, DCS, or SCADA systems.
Dynamic Vibration Analysis can be in the form of
portable or permanent measurements. In the case
of portable vibration analysis, you will need a data
collector, accelerometer, mounting magnet, and data
collector cable with the break-away safety feature.
If you are using on-line vibration monitoring,
permanently mounted accelerometers like the AC102,
AC104, AC192, or AC194 will provide dynamic
vibration signals that can be analyzed to identify
the fault frequency and amplitude of the fault or
condition of the machine. A durable cable like CB111
(Yellow Jacketed Teflon®) or CB206 (Stainless Steel
Armored Jacket) combined with the V2N (CB111
only), B2N, or A2N connectors over molded on the
cables will provide reliable connectivity back to
the on-line vibration monitoring system.
CB111
A combination of Dynamic Vibration Analysis and
Process Monitoring will require accelerometers
to measure the dynamic vibration, and a 4 wire
transmitter (SC200 series) to convert the dynamic
signal to 4-20 mA output for trending and
alarming on the DCS, PLC or SCADA systems.
In this application, if the control room notes a
change in the amplitude of the vibration via
the 4-20 mA signal, the analyst can use the
dynamic output of the transmitter to identify
the frequency fault and determine what is
wrong with the machine.
CB206
The SC200 series can even accommodate
dual output sensors. The TA131, TA102,
TA104, TA184, TA133, and TA135 provide
dynamic vibration and temperature inputs
to the SC200 series. The SC200 series signal
conditioner will then transmit the overall
vibration and temperature as 4-20 mA signals to
the DCS, PLC or SCADA systems. Combining
vibration and temperature measurements in
a single sensor, at one location, provides a
permanent and reliable assessment
of the overall condition of the machine.
