The newly developed VE series capacitive gap detector combined with the VT series converter is a capacitive micro-displacement gauge that measures the distance and displacement to the measurement target (conductors such as iron, aluminum, copper, and various metal platings) with high precision and non-contact.

It measures the gap and displacement between the sensor end face and the target surface from the capacitance of the capacitor formed by the surface of the measurement target and the end face of the VE series sensor electrode installed opposite it.

The VT-5700 series is a compact and low-cost type suitable for embedded applications, featuring two models: the VT-5710 with a response frequency of 4kHz and the VT-5720 with a high-speed response of 10kHz. It demonstrates its power in measuring and controlling the axial vibration and surface runout of rotating machines such as turbines, electric motors, and compressors, as well as the warpage, flatness, and thickness of conductors like silicon wafers and hard disks.

Due to non-contact detection, it does not impose a load on the measurement target that is rotating or vibrating, and it does not change the vibration mode either. The VE sensor is available in nine types for measurement ranges from 20μm to 8 mm.

Features

  • Measurement range from 20μm to a maximum of 8 mm, wide range.

  • Measurement accuracy of 0.2% of full scale (F.S.) with a combination of converter and sensor.

  • Max 10 kHz high-speed frequency response - High-speed response to dynamic displacement changes (VT-5720)

  • Small and low-cost type suitable for embedded applications.

  • It does not affect the measurement target for non-contact measurement.

  • All conductors are measurable - they are not affected by factors such as color, roughness, reflectivity, or external light.

*1 The measurement range indicates the maximum gap from the sensor's end face to the measurement target.
*2 The measurement surface of the target object requires an area larger than the sensor's outer diameter.
*3 The operating temperature range refers to the temperature range in which the sensor can function, but it is not the temperature range where linearity is guaranteed. To ensure linearity, please use at a temperature of 23±2°C.
