Idler Sound Monitor Module
Overview
Figure 11 - 2.
Microlog with Idler Sound Monitor Module, Earphones, and Microphone with Parabolic Reflector.
Idler Sound Monitor kit components include:
•
The SKF Microlog running the Idler Sound Monitor module (
CMXA MOD
-ISM-
SL
).
•
A high frequency microphone (CMAC 5091) secured in a rugged parabolic reflector
(CMAC 5141).
The impact resistant parabolic reflector focuses the sound to the
microphone and protects the microphone from damage.
•
A Fischer to BNC cable (CMAC 509
3) for connecting the microphone to the
Microlog.
•
Headphones for listening to the processed sounds and alarm tones (CMAC 5403).
•
H
eadphone cable (CMAC 5078) for connecting the headphones to the Microlog.
•
A wind baffle (CMAC 5143) for the microphone.
•
An adapter plate assembly (CMAC 5142) for mounting the microphone / parabolic
reflector to the Microlog.
Important - It is imperative to use headphones when operating this module. The
microphone’s parabolic reflector is directional, and misdirecting the instrument can
vastly alter measurement results. Listening with the headphones as you collect
data greatly improves your ability to “lock onto” the targeted idler rollers’ sound -
to most accurately monitor their condition.
Combining a high frequency microphone with a simple visual display and with
headphones and an audible alarm, the SKF Idler Sound Monitor allows operators to
detect faulty idler rollers with minimal training. The operator simply walks the length of
the conveyor and continuously detects faulty idlers from up to 3 m (10 feet) away.
Since the device can detect faulty idlers on the far side of the belt, there is no need to
walk both sides.
