  • Page 18: Application

    Introduction Unpacking and Inspection Application The speed sensor is coupled to a rotating shaft which drives a generator inside the housing. The Model 61-12 C Speed Sensor has a usable range between 20 and 200 RPM. The frequency of the speed sensor output signal is exactly proportional to shaft speed and provides the required speed input to a Integrator/Totalizer.

  • Page 19: Chapter 2 Installation

    Chapter 2 Installation Overview The Model 61-12 C Speed Sensor 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.

  • Page 20: Figure 2-1. Method A Installation

    Installation Overview Figure 2-1. Method A Installation Method “B” If customer's tail pulley shaft has a 5/8" diameter stub shaft extending from it and is concentric with the centerline of the driving shaft, use part #002931 to couple 61-12 speed sensor to tail pulley shaft. (Refer to Figure 2-2.) This coupling is not supplied with the speed sensor but may be purchased separately from Thermo Fisher Scientific.

  • Page 21: Restraint Arm Installation

    Installation Restraint Arm Installation Restraint Arm 1. Attach restraint arm to speed sensor with two (supplied) 5/16" x Installation 1-1/4" bolts. See Figure 2-3. The restraint arm should be mounted in a direction that will allow the sensor restraint arm to twist against the mechanical stop and in the direction of belt travel.

  • Page 29: Chapter 3 Operation

    Chapter 3 Operation Overview The speed sensor element employs a brushless, pulse generator which produces a stream of pulses, each pulse representing a unit of belt travel. The frequency of the pulse stream is proportional to true belt speed. The pulse output signal is fed to the Integrator/ Totalizer.

  • Page 31: Chapter 4 Maintenance

    Chapter 4 Maintenance Overview When performing scale calibration, it is a good practice to inspect the shaft cou- pling for tightness. Also verify that the restraint arm is free to move. If arm has worn a slot in the restraint stop and the restraint bar cannot float back and forth as well as against the spring, corrections should be made.
