Proximity sensor
VK Series
ACOEM
It measures the shaft radial vibration or axial displacement of rotating machinery without contact. This is the most appropriate sensor to measure the shaft vibration of rotating machinery supported by plain bearings and is frequently used to monitor the vibration of turbine generators and compressors.
In addition, the VK system can be used in an explosive gas atmosphere due to its intrinsic safety construction.
