Di-440The Modular Analyser



Instrument Concept

Single tool for a range of service, maintenance and inspection applications:

• Condition assessment tool – highlights state of machinery today

• NOT for Predictive Maintenance• Ease of use is critical• Enables collection of VALID data by non-

experts• Should store and record relevant data for the

use of veteran analysts• A service tool NOT a scientific instrument – as

such the user interface should be simple• Should de-mystify the use of an FFT analyser

Di-440 Modules



Conformance Check

• General machine health check using vibration measurement to appropriate standards

• User definable module for conformance standards:– Select machine classes and alarm limits– Allow vibration limits to be set by your

own vibration experts.– Library of pre-defined industry standards

available – Operator feedback: Actual values &

Machine health grading.



Conformance Standards

• Initially available library of pre-defined conformance standards:– ISO 10816-2 Land based Steam Turbines & Generators– ISO 10816-3 Industrial Machines– ISO 10816-4 Industrial Gas Turbines– ISO 10816-5 Hydraulic Power Generators & Pumps– ISO 10816-6 Reciprocating Machines– ISO 8528-9 Reciprocating Driven Generators– ISO 13332 Internal Combustion Engines– BS 4999-142 Rotating Electrical Machines– BS 4675-1 Industrial Machines– ANSI/HI 9.6.4 Centrifugal & Vertical Pumps

• Bespoke application creation service. Let us programme in your specified instrument settings.



FFT Analyser

• Allows simplified checks for common machine faults• Live display of signal spectrum• Phase reading shown as a simple vector diagram



Bump Test

• Easy identification of a structure’s natural frequency.• Can be applied to:

– Crack detection– Structural Mechanical integrity– Determination of resonant (critical) frequencies– Turbine blade testing



Balancing Module

• High precision 1 or 2 planes

• Static or dynamic couple balances

• On screen step by step guide to balancing



Recorder

• Record live vibration signatures e.g. run up, steady state & coast down

• Storage of two channel time data in industry standard (WAV) format

• Email file (via PC) to base for play back, analysis & diagnosis – import into third party packages:

Matlab, DasyLab, DADiSP, Polymate, SignalCalc
