Electrostatic capacitance-type

Example of the measurement
Specifications

By combining the latest developed VE series Electrostatic capacitance-type Gap detector, the Electrostatic capacitance-type Non-contact Displacement Meter VT series can measure the gap/displacement between a measurement target (conductors such as iron, aluminum, copper, and various metal plating) and a sensor with high accuracy without contact.
The gap/displacement between a bottom surface of the VE series sensor and the surface of a target is measured using each of electrostatic capacitance.
There are 4 models of lineup. VT-5210, VT-5710 support 4 kHz of response frequency, VT-5220, VT-5720 support 10 kHz of response frequency. The VT-5700 series is a compact and easy to install.
It is efficient to measure and control shaft deviation and plane deflection of rotating machines such as turbines, electric motors, compressors, and flatness and thickness of conductors such as silicon wafers and hard disks.
Since it is non-contact detection, the rotating or vibrating target can be measured without load.

* VT-5220 has been discontinued.

Features

Wide measurement range from 20μm up to 8 mm
High accuracy: 0.2 %FS (in combination with sensor)
High-speed response to dynamic displacement changes (VT-5220- Max. 10 kHz of response frequency)
Non-contact measurement can be performed without affecting the target.
All conductors can be measured without being affected by color, roughness, reflectance, external light, etc.

Note:
*1: The measurement range refers to the maximum gap between the surface of the sensor tip and the object under measurement.
*2: The surface measurement area of the object under measurement must be larger than the external diameter of the sensor.
*3: The operating temperature range is the temperature range in which the sensor can operate, not the operating range for which accuracy is
guaranteed. The operating range for which accuracy is guaranteed at 23±2°C. The temperature characteristics of the VE series are shown in
the formula below.
