ISO 2372 Dual Channel Touch Screen Piezoelectric Vibration Sensor
Vibration Meters Handheld
Introduction
The vibration analyzer HG3002 is specially developed for the field
portable application. It not only meets the requirements of
portable vibration collection, but also realizes the powerful field
data collection and equipment fault analysis function. It has a
very high cost performance. Vibration analyzer is an indispensable
intelligent instrument for condition monitoring, vibration
analysis, and fault diagnosis and data collection in factories. It
is also an effective assistant for equipment management and
maintenance to realize predictive maintenance.
Vibration analyzer is simple to operate, suitable for equipment
maintenance personnel, spot inspection personnel, inspection
personnel, production personnel and other groups of people to use,
the application is very common, with data measurement, recording,
analysis and other functions, timely detection of equipment
vibration fault and make a judgment.

Mechanical equipment fault analysis
According to the actual situation, through a variety of analysis
methods, can turn a subclass of diagnostic equipment’s fault (base
of the loose, unbalanced, shaft bending, axial crack, resonance,
surge, oil film vortex, oil film oscillation, rotating stall, the
rotor and stationary pieces of friction, rotor interference fit
interference, seal gap and instability). Bearing faults (bearing
wear, bearing pitting corrosion, bearing oil shortage), gearbox
faults (gear wear, gear eccentricity, gear pitch error is too
large) and other mechanical faults.
For the flow bearing and gear system, the monitoring of high
frequency pulse signal is the most basic requirement, our company
provides a special dimensionless index detection, you can quickly
confirm the rolling bearing base gear system fault, and determine
the degree of failure.
Application of equipment
Vibration analyzer is suitable for measuring the vibration of
various rotating machinery and equipment. It is a general type
instrument and meter. It can measure fans, motors, compressors,
steam turbines, and machining centers, winding machines, crushers,
grinders and other rotating machinery and equipment.
