Description –

The Pulse Duration Transmitter converts a 4/20 mADC signal to a periodic time  modulated pulse width contact closure that is connected to a dry wire pair. A Pulse Duration Receiver is connected to the other end of the dry wire pair. It detects the time modulated contact closure and converts it back to a 4/20mADC signal.

The 4/20 mADC signal may be connected to a local display, chart recorder or PLC.

The 4/20 mADC is also connected to the Intergator which converts the 4/20mADC to a proportional contact closure pulse rate which may be used to drive a totalizer, pulse a chemical feeder or be connected to a PLC.
