Capacitive non-contact displacement sensor

VT-5700シリーズ

VT-5700 series / VT-5200 series / VE series

This newly developed capacitive micro-displacement meter combines the VE series capacitive gap detector and the VT series transducer to measure distance and displacement to the target object (conductive materials such as iron, aluminum, copper, and various metal platings) with high precision and without contact.

The gap and displacement between the sensor end face and the target surface are measured from the capacitance of the capacitor formed by the surface of the object being measured and the end face of the VE series sensor electrode installed opposite it.

The VT-5700 series is a compact, low-cost type suitable for embedded applications, and includes two models: the VT-5710 with a response frequency of 4kHz and the VT-5720 with a high-speed response of 10kHz. It is highly effective for measuring and controlling shaft vibration and runout in rotating machinery such as turbines, electric motors, and compressors, as well as warping, flatness, and thickness of conductive materials such as silicon wafers and hard disks.

Because it uses non-contact detection, it does not apply load to the rotating or vibrating object being measured, nor does it change the vibration mode. Nine types of VE sensors are available, ranging from 20 μm to 8 mm in measurement range.

Inquiry

Wide measurement range from 20 μm to a maximum of 8 mm.
Measurement accuracy of 0.2%/F.S. (with converter and sensor combination)
High-speed frequency response up to 10 kHz - fast response even to dynamic displacement changes (VT-5720)
Small and low-cost type suitable for embedded applications
Because it is a non-contact measurement, it does not affect the object being measured.
All conductive materials can be measured - unaffected by the color, roughness, reflectivity, or ambient light of the material being measured.

*1 The measurement range refers to the maximum gap from the sensor end face to the object being measured.
*2 The measuring surface of the object being measured must have an area larger than the outer diameter of the sensor.
*3 The operating temperature range refers to the temperature range in which the sensor can function, and not the temperature range in which linearity is guaranteed. To ensure linearity, please use the sensor at a temperature of 23±2℃.
