Capacitive non-contact displacement sensor

VT-5200シリーズ

VT-5200 series displacement meter + VE series displacement sensor

This newly developed capacitive gap detector, combined with a VT series transducer, provides non-contact, high-precision measurement of distance and displacement to a target object (conductive materials such as iron, aluminum, copper, and various metal platings). It measures the gap and displacement between the sensor end face and the target surface from the capacitance of the capacitor formed by the interaction between the object surface and the end face of the VE series sensor electrode. Two models are available: the VT-5210 with a response frequency of 4kHz and the VT-5220 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 load the rotating or vibrating object, nor does it change the vibration mode. Nine types of VE sensors are available, covering measurement ranges from 20μm to 8mm. Capacitive non-contact displacement meter VT-5700 series (compact type for embedded applications) → *The capacitive non-contact displacement meter VT-5220 has been discontinued.

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-5220)
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℃.
