Models 61-12N, 61-12C, 60-12F, and 60-12ENC Speed Sensors must be attached to a pulley shaft which turns at true conveyor belt speed. Normally, the tail pulley shaft or a snubbing roll shaft satisfies this requirement. In installations where the tail pulley or snubbing roll shaft is not accessible, an additional pulley must be installed specifically for the speed sensor.
- 61-12N is used for speeds from 0 to 350 RPM and supplies the output of the generator directly to the totalizer for high speed operation
- 61-12C is used for speeds from 20 to 200 RPM and supplies the output of the generator directly to the totalizer for high speed operation
- 60-12F is used for speeds from 3 to 30 RPM
- 60-12G is used for speeds from 10 to 200 RPM
- 60-12ENC is used for speeds 0 to 200 RPM and has a 500 pulse per revolution encoder inside, typically is used on slow RPM applications
- 60-15UB is an under-belt mounted jockey wheel type speed sensor used where a shaft mount isn’t available
