TA202 Tachometer with calculation functions and 2 Limits

High quality tachometers by IVO, available in many different types shown below. The TA202 is equipped with a mounting plate to install the tachometer in many applications.

Two limits that can be deliberately defined under “P1” and “P2”, allow to monitor production processes.

Two tachometers allow to capture and display, for example, the rotational speed and speed at “F1” and “F2” as well as to use a calculation function programmed by the user that can be selected via “F3” and displayed. It is possible to display ratio, difference, stretching / shrinking, run time, time measurement with start and stop signal, length of period, pulse duration or measurement of pulse rate via the calculation functions.

The TA202 is also equipped with an electronic trailing needle to be assigned by the operator to “F1”, “F2” or “F3”. This maximum memorized value can be selected via “SZ” and thus displayed.

  • Tachometer with 2 adjustable limits
  • Sensor logic can be programmed
  • Pulse valuation can be programmed from 0.0001 to 9999.99
  • Frequencies processed up to 40 kHz
  • Precise measurement due to phase evaluation
  • Measurement according to measurement of lenght of period
  • Interface RS485, RS422, RS232, Analog output
