Milltronics TASS

4/30 Siemens WT 10 2009

n Overview

Milltronics TASS is a compact low-profile, wheel-driven return belt speed sensor, ideal for use on mobile crushers and in con-stricted spaces.

n Benefits

Rugged design

Easy, low cost installation

Compact, low-profile speed sensor

IP65 rated

n Application

Milltronics TASS speed sensor operates in conjunction with a conveyor belt scale, providing signals to an integrator (Milltron-ics BW100, BW500, or SIWAREX FTC) which computes the rate of material being conveyed. The trailing arm speed sensor mon-itors conveyor belt speed, with the output signal transmitted by cable connection to the integrator.

Easily installed close to the belt scale assembly, the TASS pro-vides a signal generated as the wheel rotates on the return belt. Pulses are generated by the internal proximity switch detecting the rotation of the five spoked wheel. The TASS is mounted to the static beam of the belt scale or to a structural cross member via a pivoting bracket assembly.

The TASS is a compact, low-profile, rugged speed sensor, most often used on mobile crusher applications where space is lim-ited. The TASS output can be applied to any Milltronics belt scale integrator.

n Overview

Milltronics RBSS is a high resolution, wheel-driven return belt speed sensor.

n Benefits

Rugged design

IP65 rated

Easy, low cost installation

Accurate belt speed detection

n Application

Milltronics RBSS monitors conveyor belt speed, with the output signal transmitted by cable connection to the integrator (Milltroncs BW100, BW500, or SIWAREX FTC).

Easily installed close to the belt scale assembly, the RBSS pro-vides a signal generated as the wheel on the sensor rotates on the return belt. To secure this cost-effective unit in place, position a cross bar between stringers - either just before or after a return belt idler, or use the optional mounting bracket. The weight of the RBSS ensures positive rotation of the wheel in the middle of the return belt, and pulses from the magnetic sensor are generated by the rotation of the 60 toothed speed sprocket driven by the wheel.

The RBSS output can be applied to any Milltronics belt scale in-tegrator.

Milltronics MD-36


4

n Overview

Milltronics MD-36 is a general purpose and hazardous rated shaft-driven speed sensor.

n Benefits

Standard aluminium or optional stainless steel versions avail-able for corrosive environments

Hazardous area approved (MD-36 and MD-36 IS aluminum)

High resolution, suitable for low or varying shaft speeds

Bi-directional for either clockwise or anti-clockwise belt travel, eliminating errors due to vibration

Pulley shaft or motor shaft-driven

n Application

Milltronics MD-36 speed sensor operates in conjunction with a conveyor belt scale, providing a signal to an integrator (Miltronics BW100 or BW500) which computes the rate of mate-rial being conveyed.

The sensor is directly coupled to the motor or pulley shaft to en-sure accurate belt-travel readout, eliminating problems caused by belt slippage or material build-up.

The MD-36 converts shaft rotation into a pulse train of 36 pulses per revolution using high precision dual optocouplers. The digi-tal signal is transmitted as speed input to any Milltronics integra-tor for calculation of belt speed, flow rate and totalized weight.

This high resolution speed sensor provides a frequency signal proportional to the shaft speed, enabling low or varying shaft speeds to be read accurately. The quadrature type circuitry in the MD-36 non-IS models prevents erroneous speed signals due to vibration or shaft oscillation.

The MD-36 is easily mounted and is bi-directional for either clockwise or anti-clockwise rotation.

n Design

Mounting1)

Machining on tail/bend pulley shaft per Detail A (by customer) to accommodate Siemens Milltronics speed sensor when tail or bend pulley is not supplied by Siemens Milltronics. Arresting bracket is an anti-rotation device only and must not secure or support the speed sensor. Bearing life would be greatly reduced if speed sensor is not free to float. Use anti-rotation spring to prevent mechanical oscillation of speed sensor. Grease mating surfaces to prevent seizing.

MD-36 mounting

n Overview

Milltronics MD-256 is a high resolution shaft-driven speedsensor.

n Benefits

Light and rugged design, IP65 rated

Compact and economical

Easy, low-cost installation

Accurate belt speed detection

High resolution, suitable for low or varying shaft speeds

Bi-directional for either clockwise or counter-clockwise shaft rotation

n Application

Milltronics MD-256 speed sensor operates in conjunction with a conveyor belt scale, providing a signal to an integrator which computes the rate of material being conveyed. At only 1.22 kg (2.68 lbs), it is one of the lightest and most durable units ever de-veloped for monitoring conveyor belt speed. With its rugged cast aluminium housing, it is suitable for outdoor installation, and its low weight prolongs bearing life.

It is directly coupled to a rotating tail or bend pulley shaft to en-sure accurate belt-travel readout, eliminating problems caused by belt slippage or material build-up. The MD-256 converts shaft rotation into a pulse train of 256 pulses per revolution using a high precision rotary optical encoder. The digital signal is trans-mitted as speed input to any Milltronics integrator for calculation of belt speed, flow rate and totalized weight.

This high resolution speed sensor provides a frequency signal proportional to the shaft speed, enabling low or varying shaft speeds to be read accurately. The quadrature type shaft en-coder prevents erroneous speed signals due to vibration or shaft oscillation. The MD-256 is easily mounted and is bi-directional for either clockwise or anti-clockwise belt travel.

SITRANS WS100


4

n Overview

SITRANS WS100 speed sensor is a compact, medium-resolu-tion, pulley shaft-driven belt speed sensor with magnetic mount-ing. It is ideal for aggregate and mineral processing industries.

n Benefits

Small, light-weight

Good resolution for accurate measurement, suitable for vary-ing shaft speeds

Long bearing life

n Application

SITRANS WS100 speed sensor operates in conjunction with a conveyor belt scale, providing a signal to an integrator (Milltronics BW100 or BW500, or SIWAREX FTC module) which computes the rate of material being conveyed. It is lightweight at 1.22 kg (2.68 lbs) and durable, for easy installation and pro-longed bearing life.

The WS100 converts shaft rotation into a pulse train of 8 pulses per revolution. These pulses are typically fed into a Milltronics belt scale integrator. The integrator interprets the pulses and uses them in the calculation of belt speed, flow rate, and material totalization. In non-belt scale applications, the WS100 can be used to monitor rotational speed when directly connected to a PLC.

The WS100 IS (Intrinsically Safe) version contains an inductive proximity switch which transmits the pulses via a Switch Isolator for hazardous area locations.

n Design

The input shaft on the SITRANS WS100 is coupled to the rotating shaft on a belt-driven pulley with a tapped hole, and is externally supported. The units flexible arresting strap stops it from rotat-ing with the shaft, without causing bearing stress, and can be fit-ted to any rigid member close to the sensor.

When mounting, ensure the unit and the pulley shaft are concen-tric to avoid stresses on the units bearings.

For mounting using the magnetic connector, ensure the face of the rotating shaft on the belt driven pulley is flat, and has no burrs or damage that may prevent flush mounting of the mag-netic connector. Attach the SITRANS WS100 speed sensor to the shaft; the magnetic connector will center itself as the belt driven pulley rotates.
