The VM-21 is a fully digital, programmable dual channel vibration monitor for on-line systems. It is intended to make:
-
Measurements and indication of voltage signals from different sensors.
-
Measured level comparison to pre-programmed thresholds and vibration severity indication with bar graphs and color.
-
Analysis of changes in vibration - indication of monotonous vibration increase and rapid changes in vibration.
-
Simultaneous analysis of high frequency vibration as an indication of bearing wear. Indication of HF vibration increase.
-
Supply analog output from accelerometers to data collectors and vibration analyzers for detailed analysis.
-
Produce alarms or other actions with integrated relays (two per channel with programmable action).
-
Provide 4-20 mA output for each channel.
DREAM (Diagnostic Rolling Element Analysis Module) for Windows is a complete software system for condition monitoring, automatic condition diagnostics and condition prediction for rotating machines. DREAM for Windows is designed to work with a number of data collectors and is capable of working as a continuous monitoring and diagnostic system in it's on-line mode.
DREAM is used for:
-
long-term predictions of a machine's condition and forecasts of the minimum safe operation period of the machine
-
predictive maintenance planning
-
collection and storage of machine condition data for further processing and reporting
form and load route information and unload data from portable instruments
-
set up and control measurements for on-line measurement systems
-
collect and save the machine condition data for further processing and reporting
Features:
- automatic condition diagnostics and long-term condition prediction
- issuing of recommendations for machinery maintenance based on actual machine conditions
- advanced level of reliability for detailed condition diagnostics and life forecasts
- detection of faults in the incipient stage of their development;
The VibroTek and VAST provide a full range of systems for field balancing from light systems using up to 3 balancing planes and up to 8 measurement points to professional systems with almost no limits.
The main features of the systems are as follows:
- measurement process monitoring that allows you to reduce machine runs
- program algorithms to get required balancing accuracy using the minimal number of planes and trial runs
- diagnostics of the shaft line problems which can reduce balancing efficiency
- estimation of balancing efficiency during calculations
Several options are available for VBal including:
- balancing during run-up or coast down
- balancing by relocation of non-removable balancing weights
- balancing without tacho probe
