VVB021 is an IO-Link vibration sensor designed for medium-sized slow-running machines. It is optimised for machines below 300 kW operating between 120 and 600 rpm. The sensor measures vibration velocity, acceleration, crest and temperature. Two configurable digital outputs provide machine alarm functions. IO-Link enables digital configuration and monitoring.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
VVB021 is designed for medium-sized machinery operating at lower rotational speeds. Its application range covers machines below 300 kW. The vibration velocity range extends to 45 mm/s. Acceleration measurement reaches 50 g. This supports condition monitoring of pumps, motors and other slow-running equipment.
The sensor uses capacitive MEMS technology. It measures v-RMS vibration velocity and acceleration values. Crest measurements provide additional information about machine condition. Temperature measurement supports thermal condition monitoring. These measurements can be accessed through IO-Link.
VVB021 provides two configurable digital outputs. The outputs can be configured as normally open or normally closed. IO-Link allows switching points and monitoring parameters to be configured. Short-circuit and overload protection improve output reliability. The stainless-steel housing provides IP67/IP68/IP69K protection.
