GE Mark VIeS - Vibration Displacement Application Example; Vibration Displacement Sensor

Vibration Displacement Application Example
In the following figure (Vibration Displacement Sensor), Proximitor voltage inputs to a YVIB application are measured at the
terminal board screws. Assume this sensor is connected to Channel 4 as a VibProx input (no Keyphasor).

Vibration Displacement Sensor
Example Proximitor Specifications
Scale Factor 200mV/mil
Nominal Gap Setting 50 mils
We will configure Channel 4 for the following behaviors:
• Return GAP4_VIB4 and VIB4 signals as mils.
• Set SysLim1GAP4 to LATCH True if GAP4_VIB4 ≥ 55 mils.
• Set SysLim2GAP4 to LATCH True if GAP4_VIB4 ≤ 45 mils.
• Set SysLim1VIB4 to True if VIB4 ≥ 8 mils
• Set SysLim2VIB4 to LATCH True if VIB4 ≥ 15 mils
