  • Page 4: General Information

    1-1 GENERAL MODEL VM-13V1 Vector Monitor continuously measures the vibration vector (amplitude/ phase angle). The VM-13V1 accepts the phase reference signal (1 pulse/ revolution) and the vibration inputs and indicates the vector data (amplitude/ phase angle) of the selected vibration channel and rotating speed on front panel LED displays.

  • Page 5: Composition

    1. GENERAL INFORMATION VM-13V1 1-2 COMPOSITION As shown in Fig.1.3, the VM-13V1 consisits of the following sections. a) REFERENCE section Generates the reference signal for filtering processing by the input of the phase reference signal (1P/R). b) FILTER section Accepting the vibration input and the signal from the reference part, processes the vector computation.

  • Page 6: Specifications

    VM-13V1 GENERAL MODEL VM-13V1 VECTOR MONITOR accepts vibration transducer inputs (max.11 channels +AUX) and phase reference signal (1 pulse per revolution). It provides a digital readout of selected vibration vector (amplitude and phase angle) and machine speed (rpm), and recorder outputs.
