Heavy duty monitoring equipment for the bulk handling and processing industries

Founded in 1983 Rotech systems manufacture and supply worldwide, high quality, high reliability equipment for monitoring and measuring the speed, position and direction of rotating shafts.

Rotech Systems are the worlds leading manufacturer of high quality monitoring solution products with an unparalleled reputation for reliability, durability and quality.

Major features are tough, strong, heavy duty construction, designed to operate and give years of maintenance free operation in even the harshest industrial environments, quarries, mines, etc. And simple, quick, installation.

Main applications are in the bulk handling and processing industries. Protecting conveyors, elevators, screws, crushers, mixers, etc. Anywhere were slowing down or stoppage will cause product spillage, blockage, etc. and incur downtime, lost production, cleaning up, spoilt product, etc.

Equipment Can Give Visual And/Or Audible Alarms Plus Shutdown Items Of Plant For A Speed Reduction Of Only 5% (Adjustable 5% To 90%)

Protects Against Conveyor Belt Slip, V Belt Slip, Chain Breakage, Mechanical Failure, Stoppage, Blocking, Jamming, Etc.

Industries using rotech: food, textiles, glass, grain, power generators, fertiliser, sand, gravel, roadstone, coal, steel, ore.

Introduction

Wherever materials are transported or processed by conveyors, elevators, screws, crushers, mixers, etc, there are applications for “rotech”. Heavy duty shaft motion sensors/encoders.

Food, Grain, Pharmaceuticals, Chemicals, Sand, Stone, Cement, Ore, Coal, Ash, In Factories, Quarries, Mines, Power Utilities, And Dock Installations Are All Excellent Examples.

A single conveyor may run for long periods without any problems, but not forever, the day arrives when it starts to slip or slow down and unless action is taken quickly to switch off the conveyor, crusher or plant that feeds it then a major spillage can occur.

In a large plant with many conveyors and drives the potential for problems is multiplied by every additional drive element.

1

The costs of clearing up a spillage are not simply the costs of a man with a shovel, this is the tip of the iceberg, they can include:

Damaged belts (Conveyor & Drive, “V”, Flat, Etc.).

Damaged plant & machinery.

Mechanical diggers, front loaders, etc. To clear up grain, sand, stone, ore, coal, etc.

Contamination to food, pharmaceutical, chemical, products, resulting in rejection and waste.

Whilst these costs can be considerable, they can be minor compared to the real cost.The REAL COST is the loss in Production, Throughput and Revenue whilst cleaning up.

Hundreds, even thousands of dollars can be lost for every hour a plant us not producing product.

“Rotech heavy duty motion sensors provide simple, low cost, high reliability protection against these problems.

General Description

The “Rotech” range of shaft monitoring equipment is comprised of a range of heavy duty motion sensors and associated speed relays.

The heavy duty shaft sensor is installed on the end of the shaft being monitored and sends and electrical signal proportional to the speed of the shaft to a suitable control unit.

The control unit can be a “Rotech” speed relay, a programmable controller, a computer, data logger device or other proprietary control equipment.

The alarm level of the control unit is set to just below the normal running speed of the shaft.

In the event of the shaft slowing below the set level, the control unit operates and can be connected to give an alarm to the operator and/or shutdown preceding items of plant.

Advantages of ‘Rotech

‘Rotech’ heavy duty motion sensors and encoders combine many unique design features to give the customer:-

•Simple installation

•High performance

•High reliability

•Price benefits

2

Installation

One hole drilled and tapped into the end of the shaft to be monitored, gives simple, uncomplicated, fast installation.

One type of unit covers all types of drives, conveyors, elevators, crushers, etc. Allowing standardisation of designs, installation and spares.

No target discs to design, manufacture and install.No sensor brackets to design, manufacture and install.No guards to design, manufacture and install.No on – plant adjustment or setting up required.

The ‘rotech’ unit is carried on the shaft and moves with it, it is unaffected by shaft end float, belt adjustment, etc.

Performance

‘Rotech’ motion sensors/encoders are digital pulse generators guaranteed accurate to within 0.5%, they cannot drift and require no checks or periodic calibration.

With pulse output rates from 1 pulse per rev to 360 pulses per rev, drive speeds from 5000 rpm down to 0.03 rpm (2 revs/hour) can be accurately and reliability measured and monitored.

Reliability

“Rotech” units are designed to operate and survive in even the toughest industrial environments, they have been particularly developed for the quarrying and mining industries, however their compact size makes them just as suitable for light industries.

Heavy duty castings, heavy duty sealed bearings and robust fully encapsulated industrialised electronics form the tough strong core of these units.

Extensive use is made of modern engineering adhesives and sealants to double up on the traditional precision assembly methods and ensure even greater reliability.

‘O’ Ring seals on end covers, grease chambers, spring loaded shaft seals and liquid tight flexible conduit and glands complete these units to give outstanding levels of protection and ensure the highest levels of reliability and operational life.

All Rotech units are totally maintenance free – sealed for life!

Price

Installed price is competitive or possibly lower than alternative methods, ultimate in operational life and reliability is an added bonus.

3

Applications

The principle application for “Rotech” heavy duty motion sensor is as a speed or slow down switch on plant and machinery.

They can be fitted to conveyor belts, elevators, conveyor screws, crushers, mixers, valves and any other plant that presents a hazard if it slows beneath its normal running speed.

They should always be installed at the end of the drive system.

On a conveyor and elevator they should be installed on the tail drum, tail roller, snub roller, gravity take up roller or any roller that is driven by the conveyor belt itself.

Any slowing down of the drive motor, gearbox, drive chains, drive belts, or the conveyor belt slipping, etc, will result in the conveyor belt and the selected drum/roller slowing down which will be detected by the encoder.

All elements of the conveyor are therefore monitored.

The heavy duty shaft sensor should, unless special circumstances apply, never be fitted to the drive roller or drum.

On conveyor screws the heavy duty shaft sensor should be installed to the non-driven end of the screen.

Other Applications

Shaft sensors can give information on the speed, angular position, direction and number of revolutions completed by a rotating shaft.

Via racks, screws, slides, etc all of these functions can be translated into linear functions.

Although its use as a speed switch is the principle application of “rotech” heavy duty motion sensors, they also fulfil a wide range of other applications in many types of industries.

Installation – Electrical –refer to page 6 for typical installation commissioning and testing information

1. Always complete the mechanical installation before commencing the electrical installation.

2. Install a suitable junction box within 300 – 600mm of the Motion Sensor/Encoder.

3. Gland – Off the flexible conduit of the Motion Sensor/Encoder in the junction box and connect the 2 or 3 wires to suitable terminals.(The flexible conduit and cable are supplied over-length they can be cut back and shortened as required)

4. Connect suitable wires and cable to route the motion sensor/encoder signal back to the control panel.

Important

The maximum distance recommended between the Motion Sensor/Encoder and the controlpanel is 1000 yards.

Armoured or screened cable should be used id the cable is routed in the vicinity of powercables.

Do not route the Motion Sensor/Encoder signal through multi-core cables carrying othersignals or voltages.

5. Alternative Installation

An alternative method of installation is to house the Control Module/Speed Relay etc. in a slightlylarger terminal box.

A mains signal (typically 110Vac) can then be switched on by the control module and then routedvia multi-cores; unprotected cables etc. back to the control panel.

Electrical Connection Options

Refer to pages 9-10 for details of Rotech motion sensors and encoders electrical output optionsavailable.

7

Other Applications

Motion Sensors/Encoders are used extensively in many different industries for a wide variety of applications.

Besides measuring the speed of a rotating shaft, they can determine direction of rotation, angular position, and the number of revolutions or parts of revolutions completed.

Using screws, slides, racks & pinions these angular functions can be translated into linear or length functions.

The following are the more popular applications that ‘Rotech’ Heavy Duty Motion Sensors/Encoders are utilised for.

Speed Indication

Used in conjunction with a Digital Panel Meter to display RPM or linear speed of a Conveyor Belt.

Length Measurement

Used in conjunction with a Counter unit and either a roller or wheel of known circumference, to measure cut-off lengths, total throughput, or to position material for a process operation.

Direction Indication

Using a ‘Rotech’ Heavy Duty Motion Sensor/Encoder with dual quadrature outputs, direction of rotation can be determined.

This is most frequently used to detect if a heavily loaded conveyor starts to run backwards.

VS 4000 SeriesVibration Sensor Relay

Application InformationWhy Accept Anything Less?ROTECH FOR RELIABILITY!

From a pilot introduction starting in 2000, Rotech Systems now have over 200 VS 4000 Vibration Protection Systems inoperation.

Most modern screens are designed with the benefit of computer simulation and can therefore cope with a wide rangeof operational conditions.

Variations in feed rates and composition of the material being fed to a screen (wet, sticky, etc.) can however in somecircumstances result in an excessive amount of material being on the screen.

If as a result, the rate and speed of vibration of the screen slows down, even temporarily, problems can occur veryquickly.

Material continues to be fed to the screen at the normal rate but the slowdown causes the discharge rate to be reduced, a marginal overload can quickly enter a runaway situation with the material arriving at the screen causing an every increasing overload and further slowdown, the discharge rate is then further reduced and the overloadincreases exponentially.

Mechanical Failure – “V” Belt damage or the intervention of the screen drive motors electrical overload is often the first thing the operator will know that all is not well!

Overloaded screens and feeders, V belt damage, spillage, cleaning up, etc. and their associated downtime and lost production can now be a thing of the past.

Key elements in the design brief were:-Quarry environment construction to ensure long term reliability, easy installation and simple setting up.

A ‘Rotech’ vibration sensor, fitted to screen, monitors its rate of vibration and will operate an alarm or switch the in – feed conveyor off if the screen slows down.

Accuracy is such that even a drop in speed of 5% for a few milli – seconds can be detected and action taken almostinstantaneously.

On V – belt driven screens, the screen drive motor can be switched off the instant any slippage occurs, preventing costly damage to belts.

The VS 4000 Vibration sensor is housed in heavy duty aluminium housing with all internal components and cable connections fully encapsulated.

It is supplied complete with a heavy duty galvanised angle bracket that is simply bolted or welded to the side of the screen or feeder. A heavy liquid tight flexible conduit is then looped to a convenient electrical junction box and the signal

routed by standard PVCSWA cable back to the main control panel.The associated SR 4000 Speed Relay Control Module has a single dial that is turned to locate the actual running speed of the screen / feeder and then set to just below this speed.

Typically on a screen / feeder vibrating at 750 throws per minute the speed relay is set to 725, if the speed drops below this level the SR 4000 speed relay operates in less than 10 milli – second.
