Electronic counter LUCA-2

Electronic counter LUCA-2 is destined to count the impulses coming from the non-contact or contact sensors. It can distinguish the direction (attribution, subtraction). Read values are counted in two independent units and you can swich displaying of these on the counter display. One of the unit can be set by program for example as the velocity meter.


Electronic counter LUCA-2

Key features:
  • Counting impulses in both directions (attribution, subtraction).
  • Counted in two independent units, one unit can be set as the velocity meter.
  • Parameters and values are showed on the LCD display (units can be switched).
  • Presetting of final counted value and presetting of response by reaching it (impulse duration).
  • Counter Luca-2 is suitable for measuring of length in textile, paper and rubber industry together with measuring wheel OK-III.
  • It is possible to use the counter like approved measuring device - (it can be sealed by metrological inspectotrate after counting constant is set).

There are two inputs for impulses counting. There is the keyboard to input the values and to make settings. Both measured and input values are showed on the LCD display (height of digit 12 mm). There is the voltage of 16 - 24 V to supply sensors, inputs and outputs. There can be up to 4 outputs including 2 relays. All the device is placed into the plastic box with protection IP 66. According to the number of incomimg and outcoming cables there can be bushings done, by the instalation there are no more protection parts necessary.



Parameters of the counter can be modified:

  • by exchanging parts or by program settings by the producer - number of presets, number and type of parameters of input and output, constants, the way to reset (zero), operation mode - two counters or counter and velocity meter
  • by the user in SETUP - setting of the decimal point, ratio between the counters, one-direction counting, both-direction counting, preset duration


In standard configuration LUCA-2 is set to 2 counting units with 2 impuls preset with duration 0,4 s. One counting unit displays 2 decimal places, one counting unit displays integers (constant of ratio: 100).
Counter Luca-2 is suitable for measuring of length in textile, paper and rubber industry together with measuring wheel OK-III. It is possible to use the counter like approved measuring device - (it can be sealed by metrological inspectotrate after counting constant is set).
