Description

The 3300/55 Dual Velocity Monitor provides two channels of continuous on-line machinery vibration monitoring. The monitor accepts inputs from one or two Velomitor® transducers, High Temperature Velomitor Systems (HTVS), or Velocity Seismoprobe® transducers without the need for interface modules. Flexibility is designed into the Dual Velocity Monitor. Many user-selectable options, such as high- and low-pass filter corner frequency options, can be easily (re)programmed in the field with plug-in jumpers
