  • Page 13: Chapter 1 Introduction

    Chapter 1 Introduction Overview The Thermo Scientific Model 60-12 Speed Sensor is designed and constructed for direct connection to a conveyor tail pulley, snugging roll, or large diameter return roller. The speed sensor employs a brushless pulse generator producing a stream of pulses, each pulse representing a unit of belt travel.

    RPM. The 60-12F is used for speeds from 3 to 30 RPM, and the 60-12G is used for speeds from 10 to 200 RPM. The 60-12 ENC Speed Sensor has a 500 pulse per revolution encoder inside, typically is used on slow RPM applications, and has a range of 0 to 200 RPM.

  • Page 15: Chapter 2 Installation

    4. Thread in supplied stub shaft coupling (part #037711) so that coupling collar bottoms out against tail pulley or snubbing shaft. See Figure 2-1. 5. Insert 60-12 speed sensor into coupling. Be sure to align shaft flat spot with set screws on coupling. Tighten all set screws securely.

    #002931 to couple 60-12 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 17: Restraint Arm Installation

    Restraint Arm Installation 1. Attach restraint arm to speed sensor with two (supplied) 5/16” x 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 18 Figure 2-3 Mounting Illustration Speed Sensor must not be mounted rigid. Use restraint arm and retaining spring. Mechanical stop and spring mount are by others. Attach spring in location such as to give 1/2” spring stretch. All wiring by others in accordance with system field wiring diagram and applicable codes.

  • Page 21: Electrical Wiring

    Electrical Wiring Use the following procedures to make electrical connections: Remove the terminal strip cover (Figure 1-1) and the dust plug from the threaded conduit aperture in the speed sensor housing. Install 1/2 inch flexible conduit to the speed sensor housing. For 60-12C speed sensor, use Beldon 8760 or equivalent, 2 conductor, 18 AWG, shielded, when total length between speed sensor and totalizer is 200 feet or less.

    Figure 3-2 60-12C Output Voltage Model 60-12F Speed sensor Model 60-12F is designed for use in low speed systems (3 to 30 RPM). The 60-12F outputs 200 pulses per revolution, and requires and external power source of 15 to 30 VDC to operate. It contains a two-phase servo generator. The rotor is a 50-slot permanent magnet that is rotated in the stators.

  • Page 29: Chapter 4 Maintenance

    Chapter 4 Maintenance Overview When performing scale calibration, it is a good practice to inspect the shaft coupling 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.
  • Page 30 4.3.3 60-12 ENC Place a DC voltmeter across field terminals 17 (+) and 16 (-) of 60-12 ENC speed sensor. Depending on Model of scale integrator, reading should be 20, 24 or 30 VDC. If no voltage present, check at integrator terminals (see scale integrator manual).
