Industry Applications
The Vibro Meter 913-402-000-012/A2-E045-F0-G00 is suited for continuous vibration monitoring on turbomachinery, pumps, and compressors in oil & gas, petrochemical, and power generation facilities. Its Ex i rating allows safe installation in Zone 0/1 explosive gas environments. For example, in a gas turbine train, this proximity probe measures shaft displacement even when exposed to high-frequency power from an IQS900 signal conditioner, ensuring early detection of bearing wear or imbalance.
Maintenance & Reliability
To maximize the service life of your Vibro Meter 913-402-000-012/A2-E045-F0-G00, implement regular inspections of the integral cable for cuts or abrasion. The IP68 rating allows submersion, but in practice ensure the self-locking connectors remain hand-tightened. Although the transducer can survive short-term temperature spikes above 180°C, prolonged exposure will accelerate drift. Environmental factors such as aggressive chemicals are mitigated by the FEP sheath option. By following these checks, you reduce unplanned downtime and extend replacement intervals.
Selection Guide & Purchasing Advice
Before ordering, verify that your signal conditioner is compatible with the high-frequency power source requirement (IQS900 series). The extension cable length is fixed at 4.5 m ± 450 mm, so measure your installation distance. If additional mechanical protection is needed, consider the optional flexible stainless steel hose (specify option F=0 in this variant).
