Why Online Condition Monitoring?

Easy recording of measurement data - even at difficult-to-reach measurement locations

Reduction of unscheduled shutdowns

Lower personnel costs and time overheads for recording measured data

Immediate alarm notification if condition deteriorates

Telediagnosis by external experts - reachable at any time and from anywhere

Less warehousing of spare parts due to maintenance planning

Operation

Short measurement cyclesPermanently supplied transducers reduce the measurementcycles to a minimum - ideal, for example, for machines withvariable RPMs or changing load.

Convenient remote accessCheck alarms, overall values and status information online- from any PC with an Internet browser.

Evaluation & archiving of dataStraightforward data evaluation, archiving and setting up of themeasurement parameters with OMNITREND PC software

Optional EX protection Analog outputs (4-20mA)

24V power supplyVIBNODE can be connected to an existing 24V power supply (e.g. machinecontrol). No additional AC power line must be laid.
