Detailed Product Description


Solid state Pulse Transmitter provides fast & accurate signalingforremote indication, totalizing & data monitoring systems. Itismounted directly on Flow Meter output shaft.


DESIGN FEATURES

  • High resolution of 100 pulses / revolution, dual channel
  • Very low power requirement.
  • Low driving torque places minimum load on Flow Meter shaft.
  • Not affected by line vibration.
  • Explosion proof housing certified by CMRI, Dhanbad, India for use inGroup IIA & IIB hazardous areas.
  • Wide operating range within 1000 metres of receiving instrument.

PRINCIPLES OF OPERATION


Theunitconsists of a precisely slotted disc rotating through a solidstateoptical switch which houses an infrared light source & alightsensitive diode. The optical switch detects the passage of theslots onthe disc as the input shaft rotates & translates them withthe helpof an in-built electronic circuit into positive square waveoutputpulses. One revolution of the input shaft produces 100 pulses attheoutput.



APPLICATIONS

  • Operating remote Electronic Counters to indicate Flow Meter throughput.
  • Operating Preset Counters to control preset quantities through the Flow Meter.
  • Operating flow recording & flow rate indicating instruments.
  • Data acquisitions systems.
