Veeder-Root 7671 Solid State Pulser (100:1) directly controls an electric current with a magnetic field, eliminating moving contacts. Two magnetically sensitive digital integrated circuits and two revolving magnetic disks with supporting hardware generate a pulse train. This pulser provides a single (100 ppr) or dual channel (50 ppr).
Note: The 7671 Pulse Transmitter is UL Listed and CSA certified for use in hazardous locations.
