WB MAN WET 2CH node
Marposs has designed WB (Wheel Balancer) Nodes for active vibration controls on grinding machines that can be used to compensate for wheel imbalance. The vibration (ACC) and rotation speed (RPM) sesnors can be connected using quick-release connectors. In order to meet the active vibration control requirements in a wide range of applications, various different types of sensors are available:
- ACC - Vibration sensors with axial or radial cable output
- RPM - Inductive, magnetic or optical rotation speed sensors
Each WB Node is manufactured in stainless steel and may be installed directly in the working area (WET area), at a short distance (typically 3 m) from the single sensors. The Nodes convert the analogue signals from the individual sensors to digital signals. In this way it is possible to transfer the values to the system Master via the MMSB (MarpossMeasure System Bus) in digital format, thus avoiding the Signal to Noise ratio quality issues that affect analogue signals, and which are the result of the length of traditional cables.
The WB Nodes can be connected together using the dedicated accessories or, depending on the topology of the network managed by the MMSB, by using the special cables, which have been designed, together with their connectors, to withstand the typical conditions inside the machine working area.
