Double Sheet Metal Monitor BDK Compact BDK/I-1.4 (Ref. no. 20.21-03) Sensor & Technologies Features Compact Double Sheet Metal Monitor for the connection of one sensor for single-surface contact measurement of ferrous (Fe) sheets. Easy handling and teach-in-programming. Double Sheet Metal Monitor BDK/I-1.4 (BDK Compact) can be used wherever you need to be sure that ferrous metal sheets do not exceed a specified thickness (double sheet). Measured sheet thickness can be provided for processing in a control system (PLC) with semiconductor relays for “0, 1, or 2 sheet(s)” message or as an analogue value. The Double Sheet Metal Monitor has a sturdy plastic housing. The ready-made connecting leads permit quick and easy connection of the metal thickness sensor. A 9-pole M23 connector allows to connect the power supply, the controlling signals and the analogue output. The sensor can be mounted into the suction cup of the gripper or into a monitoring station. For measurement, the complete sensing face of the sensor must be covered by the sheet. The metal thickness sensor DSP for single-surface, contact measurement is used to monitor sheets for double thicknesses in the range 0.15 to 4 mm. During measurement, an excitation coil generates a strong magnetic field. The sheet is briefly drawn towards the coil and magnetised to saturation. A sensor coil measures the magnetic flux, the evaluation device linearises the measured value and transforms it into an analogue signal. Measurement can be started by an external signal or pressing “Start” on the control panel. When a continuous start signal is applied, measurement is carried out every 500 ms. Teaching the thickness of the current reference sheet is carried out using the control panel or by an external Teach-in signal. During this procedure three measurements are taken automatically. The resulting sheet thickness is stored as reference value. If a thickness more than 1.3 times that of the reference sheet is measured, “Double sheet” is signalled. If the measured thickness is less than 0.5 times that of the reference sheet, “No sheet” is signalled. If a double sheet is detected, the switching output for 1 sheet changes from Hi to Lo. For the operation there are four operator keys on the control panel: Start Manual start of a measurement - Decrement limit value or calibrate zero value + Increment limit value or calibrate end value Teach Teaching of the reference sheet In addition, 5 LEDs indicate the result of the current measurement.

Sensor & Technologies Double Sheet Metal Monitor BDK Compact BDK/I-1.4 (Ref. no. 20.21-03) Commissioning When the device is used for the first time or after changing any component in the system, the system, and thus the measuring range, must be recalibrated. When using the DSP-54sg-2s sensor, this is done by teaching the zero setting (measurement without a sheet) and the end value with a 4 mm calibration sheet. When using the DSP-36sg-2s sensor, teaching is performed with a 2 mm calibration sheet. Calibration will be performed as follows: Remove the sheet from the sensor and press the “-“ key...
