Sensor & Technologies Double Sheet Metal Sensor BDK Duo Flex BVD, BVF, BV/S (Ref. no. 13.35-11, -13) Application The BDK Duo Flex sensor is used for non-contact monitoring of sheet metals and is especially suitable wherever it is essential to avoid handling marks on the surfaces. The transmitter and the receiver modules are mounted separately, and so can be easily and quickly installed to become integral parts of your plant or machinery to reliably detect sheets at different locations. Measurement can be made while sheets are moving on a conveyor and ensures the quick and reliable detection of double sheets even when there are large air gaps, for example with textured surfaces such as studded or ribbed sheets. They are suitable for monitoring ferromagnetic sheets with a thickness of 0.1 mm to 2 mm and non-ferromagnetic sheets with a thickness of 0.1 mm to 10 mm for aluminium, or 0.3 mm to 10 mm for stainless steel. BDK Duo Flex consists of a transmitter and a seperate receiver with integral evaluation electronics. The transmitter produces an alternating electromagnetic field which is evaluated by the receiver. The sheet to be measured between transmitter and receiver attenuates the alternating field in approximate proportion to the sheet thickness. The sheet between transmitter and receiver must completely cover the sensor's active sensing face (diameter 38 mm) and extend at least 38 mm around it on all sides. The minimum distance between transmitter or receiver and sheet surface is 10 mm. When mounting, the active sensing faces must be concentric and set at a fixed distance of 50 mm between transmitter and receiver modules. The BDK Duo Flex is fitted with an M12 connector for the power supply and control and signal function. The number of the detected sheets is available at two semiconductor outputs (K0 and K1). There are three LEDs for visual monitoring and for calibration indication. Optional versions with non-linear analogue current-output to assist, for example, threshold value monitoring in a post-connected Programmable Logic Controller (PLC). Calibration initiated by the high active control input Teach-In. It consists of two equal parts (two step calibration). For sheet thickness and sheet type. The evaluated calibration parameters are stored in a non-volatile memory (EEPROM) so that they are available even after a power failure. Note: If LED does not come on after first turn on, please press start signal at PLC. To start calibration, the control input Teach-In must be set for approx. 2 seconds to Hi (high level signal) while Start is Lo (low level signal). The green LED blinks during calibration and is switched off after first calibration step. Yellow LED is switched on. To start the second calibration step, Teach-In must again be set to Hi for about 2 seconds. The yellow LED blinks during calibration and switches off when calibration has finished. Sheet metal must be between transmitter and receiver during either the first or the second calibration step. Sheets of different thickness and type require recalibration. If calibration is started by mistake, it may be stopped before second calibration step begins (see timing diagram Teach-In) by setting the control input Start to Hi for at least 400 ms. The sensor then returns to its previous operating mode. After every measurement the current result (0-, 1-, or 2-sheet(s)) is available at two semi-conductor outputs for further processing in a Programmable Logic Controller (PLC).

As long as this is set to Lo, the sensor is on standby and stores the last measuring result. Measurement is possible as long as the sheet is within the measuring range. For a continuous measurement the control input has to be set to Hi. 6 Teach-In signal Only for Ref. no. 13.35-13 Transmission signal The housing must be earthed with the available earth connection.
