Thickness gauge 2VD
The 2VD thickness gauge is a precise, easy-to-use and professional thickness gauge for measuring the thickness of voluminous nonwovens and comparable products made of paper and plastics according to DIN EN ISO 9073-2 point 5.2 and EDANA 30.5-99 point 4.2 with a maximum thickness of 20 mm (specified in the standard).
The 2VD thickness gauge is a measuring device with horizontal guidance of the pressure stamp. This movement into the measuring zone does not generate any pulse-shaped pressure forces above the specified measuring pressure. The initial static friction that occurs when the measuring point is reached is extremely small at < 15 µNm and does not affect the measuring result. The measurement is always carried out when the pressure stamp and reference plate are plane parallel.
Features:
Sample size: 130 mm x 80 mm +-5 mm pressure stamp: 2500 mm² Reference plate: 1000 mm² Thickness measuring range: 40 mm Scale division value:0,001 mm Measuring pressure:0,020 kPa Repeatability: max. 0,04 mm Measuring point width: 0,04 mm interface: USB / RS232 (Required cable not included) Power supply clock: Battery 2x SR44 or with USB/RS232 cable via PC Power supply: USB-Hub Dimensions: 370 mm x 165 mm x 215 mm Weight approx:15kg | Device description The measuring device consists of a digital micrometer with an integrated pressure stamp and a precision-mounted reference plate. This is coupled to a measuring device that generates signals. The first signal (orange LED) is a proximity sensor, this signal is approx. 0.08 mm (approx. 1/8 revolution of the spindle) away from the measuring point. This is for better operation. The second signal (green LED) is the measuring point. The measuring point has a width of 0.04 mm. At the measuring point, the reference plate and the pressure stamp are plane-parallel. The measuring pressure at the measuring point is exactly 0.020 kPa. The third signal (red LED) indicates that the measuring point has been exceeded. |
Measuring method:
Every time the micrometer is switched on, the zero point must be set.
The "+/-" button must then be set so that the value of the micrometer increases positively when it is subsequently opened. The sample is suspended between the pressure stamp and the reference plate using the needle provided. The sample is measured by slowly turning the micrometer towards the reference plate. The measuring point is reached when the green LED lights up. After the standard waiting time has elapsed, the measured value can be accepted. If the measuring point is exceeded, the measurement must be repeated by opening the sample window again and repeating the approach.
It must be noted that the measurement is always carried out from the right side, i.e. always from the open sample window against the reference plate.

Interface:
The measuring device can be connected to a PC via the standard USB / RS232 interface.
The appropriate data cable can be ordered from us as an accessory.
