SHINKAWA VM-5P3-1-00-00-0/IS0 Phase Marker Module
Overview
The Shinkawa VM-5P3 is a Phase Marker Unit designed for the VM-5 series machinery protection system, converting keyphasor signals from rotating machinery probes into shaped pulses for speed measurement, phase referencing, and diagnostic analysis.
With a 2-channel input and buffered pulse outputs, the VM-5P3 delivers reliable phase reference signals essential for shaft vibration analysis and balance monitoring of turbomachinery in power, oil, and gas applications.
Engineering & Design
The unit accepts keyphasor signals from eddy-current displacement sensors such as the VK-202A and RD-05A targets, with an input impedance of approximately 10k ohm and 2 available channels for redundancy or multi-keyway monitoring.
Signal conditioning shapes the raw keyphasor pulse and drives a 50-ohm impedance buffer output, delivering a clean, stable phase marker to the VM-5 monitor channels for synchronous vibration analysis.
Key Features
