Application

  • The 5725 measures, scales, and displays frequency signals found in many process speed and flow rate applications.
  • The indicator can measure the period of the frequency, useful for displaying the elapsed time between events.
  • The 5725D has two SPDT setpoint contacts and a 0/4...20 mA output for process control.
  • The installed display provides IP65 environmental sealing, and additional protection is provided by the optional 8335 splash proof cover.

Technical characteristics

  • 4-digit display with 13.8 mm high, 14-segment LED digits and adjustable decimal point.
  • Indicator is scalable from -1999 to 9999.
  • Scrolling help text makes programming easy.
  • Customizable trigger levels allow measurement of nearly any pulse sensor.
  • Built-in excitation source for measuring NPN, PNP, NAMUR and S0 sensors.
  • Fast response time of 1 cycle + 100 ms, and excellent accuracy of better than 0.05% of selected range.
  • The analog output current on the 5725D can be dampened from 0.1 to 60 seconds, and can handle up to 800 Ohms loop load.
  • The 5725 meets NAMUR NE21 recommendations for high performance in harsh EMC environments.
  • High 2.3 kVAC galvanic isolation, and an excellent signal/noise ratio of > 60dB.
