2. Software features:
a. FFT analysis capability with high resolution # 1800 lines minimum..
b. Trend data (discrete and dynamic data records), Alarm/Event data (discrete and dynamic data records), Transient data (discrete and dynamic data records)
c. Analyze the parameters using defined FFT frequency spectrum bands with tracking filters to extract machine failures as the following’s failure modes: Unbalance, Resonance, Misalignment, Mechanical looseness, Bearing degradation, Pump cavitation, internal pump hydraulic problems.
d. When an event trigger input is received, the module shall retain a historical data record of overall vibration levels and programmable frequency band vibration levels plus the last frequency spectrum for each channel. The data record must contain at least 40 discrete and 64 dynamic data samples each channel taken at a time interval that is programmable down to one second and retained until reset. The data shall be accessible either locally or via the communication network when utilizing appropriate software.
e. Static Measurements must include: Eccentricity, differential expansion, eccentricity, thrust, road drop.
f. The software must present a complete picture of the pump with fault frequency calculator, statistical based alarms, rule based diagnostic. Graphics must be easy to understand. Long term storage ( in an open database -MS SQl) of all measured and calculated parameters – to provide predictive maintenance , historical trending and diagnostics.
3. Data Interfaces : OPC Server: Including OPC server for data output (Export), OPC Client: Including OPC client for data input (Import)
