2.1 Measurement Modes
The EX-V series provides the following four measurement modes: "Bottom-dead-
center mode", "Eccentricity/vibration mode", "Thickness/gap mode" (which are
basic modes for quick operation), and "Manual mode" (which allows users to
perform setting as desired). This section explains the major functions of each
mode.
2.1.1 Bottom-dead-center mode
This mode is used to measure the displacement of the origin position of a machine
with stroke movements such as a press. When the displacement of the bottom
dead center or origin position is out of the preset tolerance range, the sensor
outputs an Alarm signal.
Major applications
• Detecting the bottom dead center position of a press
• Detecting the bottom dead center position of a press-fit machine
• Detecting the bottom dead center position of a welding machine
• Pressure control for a injection molding machine
• Measuring the depth of the recess on a piston head
2.1.2 Eccentricity/vibration mode
This mode is used to measure the roller eccentricity or abnormal machine vibration.
When the amplitude of the runout or vibration is larger than the preset tolerance
limit value, the sensor outputs an Alarm signal.
Major applications
• Measuring roller eccentricity
• Measuring surface plate runout
• Detecting runout due to improper chucking
• Measuring drill bit eccentricity
