level settingz MODEL-1592 is a 2CH type vibration monitoring
instrument.
z It contributes to monitoring of multiple points
through space saving and low cost.
z Two alarming points of “Alert” and “Danger” canbe set for measurement values. In case the set
point is exceeded, a relay contact is output.
z The 4-20 mA output is provided for the use of asequencer installed at subsequent stage. Longterm and short-term trends can be investigated bymonitoring the 4-20 mA output.

Vibration monitoring instrument for plant machines
Example of mounting sensors on a
vertical type centrifugal pumpVibration certainly increases as themachine deteriorates.

Image whenhoused in a panelz Predicting maintenance timing by using the vibration
monitor enables laborsaving and planned spot maintenance.
z The machine can be stopped and inspected beforesignificant failure occurs.
z Serious loss due to unpredicted stop of the machine isreduced, thereby providing large benefit.
z With the 2CH type, vibration monitoring at low cost ispossible.
Two sensors are horizontally mounted in the X
and Y directions so as to be perpendicular to
the rotating shaft of a pump.

Examples of implementation

Power generation stations, iron mills, chemical plants, mineral oil refineries, factories, water and sewage facilities, and otherplants overall

Examples of machines

Turbines, fans, blowers, pumps, compressors, jet fans, cooling tower fans, motors, agitators, centrifugal separators, spindles,machine tools, spray driers, other rotating machines, and facilities overall

Vibration monitoring modez Displacement: Recommended frequency range of 5 Hz to several hundreds Hz
As sensuously easy to understand, this mode is used in a wide range of fields. Vibration of a whole machine, such as
unbalance of rotating bodies, is well measured. High frequency vibration cannot be measured.
z Velocity: Recommended frequency range of 10 Hz to 1,000 Hz
JIS B 0906 (ISO 10816) uses vibration velocity as a criterion for evaluating vibration on rotating machines. This mode isuseful as a reliable indicator for facilities diagnosis.
z Acceleration: Recommended frequency range of 10,000 Hz at mostThe acceleration mode is superior in detecting stress waves generated by micro defect, as this mode is sensitive in a domainof the large number of vibration (high frequency). The mode is used for diagnosing local vibrational defect such as damageof roller bearings and chip of gears.
