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
- Flameproof enclosure
- High resolution of 100 pulses per revolution
- Two separate Pulse Trains
- 90 Degree Phase shift between dual Pulse O/P
- Level “A” Pulse security as per IP 252 & API Chapter 5
- Uses Eltomatic, Denmark make Encoder (CE marked, IP65/NEMA4 certified)
- Very low power requirement
PRINCIPLE OF OPERATION
The unit consists of a precisely slotted disc, rotating through a solid state optical switch, which houses an infrared light source and a light sensitive diode. The optical switch detects the passage of the slots on the disc, as the input shaft rotates and 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 and flow rate indicating instruments
- Data acquisition systems
