Solid State Pulse Transmitter

Solid_State_website_2.JPG

These solid state pulse transmitters provide fast and accurate signaling for remote indication, totalizing and data monitoring systems. They are UL listed and CSA certified for gasoline pump computers and applications that require pulsing of output shaft rotation in hazardous locations.

The output can be either dual channel with 50 pulses per revolution per channel or single channel with 100 pulses per revolution. The dual channel pulse trains can be staggered or overlapping. A staggered output allows errors to be detected on either channel or on both concurrently (power loss to pulser). An overlapping output permits the detection of direction of rotation and errors on either channel but not on both concurrently. The single channel devices are used when greater pulse density is desired and error detection is not required.
