  • Page 29: Software

    ADDI-DATA software is based on the principle of a virtual board: it transposes the different functions (e.g. digital inputs, analogy outputs, timer, ...) of all inserted ADDI-DATA boards as the functions of a single (virtual) board. The virtual board features a pool of functions, the functionality of which can be called up without calling a specific board.

  • Page 43: Board Calibration

    Functions of the board APCI-3701 The board APCI-3701 has up to 16 analog inputs. It is typically designed for acquiring measurement signals of inductive displacement transducers. Therefore the board provides all signals required for supplying the inductive transducers. The primary circuit of the sensor is excited by means of a sinus generator.

  • Page 44: Primary Circuit

    APCI-3701 Functions of the board Primary circuit 9.3.1 Sinus generator The sinus generator generates a sinus signal for the excitation of the primary circuit. The frequency and the amplitude are set through software according to the connected sensor type. The frequency can be set with 14 predefined values in a range from 2 to 20 kHz (See Table 4-1).

  • Page 45: Secondary Circuit

    Functions of the board APCI-3701 Secondary circuit The incoming measuring signals are driven through 2 separate 8:1 multiplexers. Each input level is then amplified by a programmable amplifier. The measuring signal is driven through analogue filters (pass band filters) with edge frequencies of 500 Hz and 32 kHz and acquired simultaneously with the feedback signal (return line signal) in the A/D converter.

  • Page 46: Transducer Principle

    APCI-3701 Functions of the board Transducer principle The inductive transducer is basically used for precise measuring travels. It is a travel/voltage sensor, the output voltage of which changes linearly along with the moving ferromagnetic core. The ferromagnetic core moves according to a straight line in a transformator, which consists of a central primary coil and 2 external secondary coils (cylindrical windings).

  • Page 47: Lvdt Transducer (Series-Opposed)

    Functions of the board APCI-3701 9.5.2 LVDT transducer (Series-opposed) The series-opposed transducer features 3 inductive coils, one primary coil and 2 secondary coils. These coils are positioned concentrically around the mobile core and form two symmetrical transformers with respect to the electrical zero point of the transducer.

  • Page 48: Possible Acquisitions

    APCI-3701 Functions of the board Possible acquisitions The board APCI-3701 generates the sinusoidal supply voltage and evaluates the measuring signal. Each channel can be independently acquired (single mode; See Fig. 9-5) The board can acquire the channels in sequences: n sequences can be carried out; 1 ≤ n ≤ 65.535 (See Fig. 9-7) n sequences can be divided in k sequences.
