PULSE TRANSMITTER

Solid state Pulse Transmitter provides fast & accurate signaling for remote indication, totalizing & data monitoring systems. It is mounted 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 in Group IIA & IIB hazardous areas.
• Wide operating range within 1000 metres of receiving instrument.

PRINCIPLES OF OPERATION

The unit consists of a precisely slotted disc rotating through a solid state optical switch which houses an infrared light source & a light sensitive diode. The optical switch detects the passage of the slots on the disc as the input shaft rotates & translates them with the help of an in-built electronic circuit into positive square wave output pulses. One revolution of the input shaft produces 100 pulses at the output.

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.
