Istec VibSys® – continuous vibration monitoring for every pump, fan and motor
VibSys is a compact DIN-rail vibration monitoring system and cloud gateway from Istec. It brings continuous condition monitoring to balance-of-plant machines that today only get a manual check every few weeks. Supplied in Finland by MK-Controls Oy, Istec distributor.

Not limited to Istec sensors
Istec VibSys is not tied to Istec-branded vibration sensors. Compatible IEPE accelerometers from other manufacturers can be used. Sensor selection should match the machine speed, frequency range, temperature, environment, mounting method and measurement objective.
Condition monitoring and integration
- Continuous machine-condition monitoring
- Four vibration inputs for compatible IEPE accelerometers
- Machine-side data acquisition and predefined extractions
- Local plant integration, including Modbus TCP
- Connection to Istec Sphere for vibration analysis where specified
- Distributed architecture for pumps, fans, motors, gearboxes, compressors and other rotating machinery
Condition monitoring—not machinery protection
VibSys is intended for condition monitoring, trending and diagnostics. Safety-critical machinery protection, overspeed trips and shutdown functions should use appropriate dedicated protection systems.
Sensors, accessories, integration and Istec Sphere subscriptions are scoped separately unless specifically included in a quotation.
Firmware: current VibSys units ship with A01 firmware. The upcoming M40 firmware adds more functions through a normal firmware update – Istec has informed that the hardware stays the same.
