System Requirement Specification’s and System Design Specification Documentation

R&B Industrial can assist with or carry out the Control/ Automation System; ‘System Requirements Specification’. This specifies the reasons/objectives for providing the system and can be used as reference for project verification/validation. 

Any expected performance benefits e.g. economic gain, quality, production improvements, can be stated together with reference to verification documents, methods, procedures etc. Other benefits should also be stated i.e. safety enhancements, improved or new functionality, resource efficiencies, etc.

Once the SRS has been completed and the project successfully tendered, R&B Industrial can produce a System Design Specification (SDS), based upon the SRS.

  • The System Design Specification (SDS), provides a complete design record of the system based on the following principles:   
  • That every part of the system has been designed to do something and therefore has a function which can be described
  • That all the functions of a complete system can be fully described by breaking the system down into its subordinate parts and also be describing these and their interactions and relationships.
At this point the SRS is ‘frozen’, referred to as Design Freeze. We will then: 
  • provide project scope of supply, schedules and timescales.
  • commence system manufacture, 
  • order in equipment,
  • start software configuration, if required
  • start system build.
We can provide low cost interfaces to the vast majority for sensors, for example:
  • Interface to the majority of thermocouples,  
  • 4-20mA,  0-10V etc. analogue inputs (AI’s) from virtually any analogue sensor.
  • frequency/pulse inputs (I/Ps),  from encoders/ tacho’s etc. (10Hz - 1MHz)
  • analogue outputs 4 - 20mA,  0 - 10V etc. for interface to PLC’s and/or control if required.
  • digital relay outputs, e.g. for local alarm i.e. sensor fail, high temp, level/flow alarm etc.
  • provide signal linearisation and isolation,  simple maths functions i.e. totallizing, limit checking, mass/flow, temperature compensation etc.  Derived signals can then be used locally to control plant and remotely for data acquisition.
  • Digital communications:  Ethernet, RS232 / RS485 and Network Comms. i.e. MODBUS,  to interface directly into a suitable data acquisition package.  Giving capability of linking many remote sensors around the plant, simply into Data Acquisition System.


Dust extraction Constant Airflow Controller

In all dust extraction systems, airflow varies according to filter pressure.  Ideally however the airflow should be kept constant throughout the life of the filter.  As an alternative to a motor inverter control, R & B Industrial have developed a Constant Airflow controller, via modulated damper, as a cost effective and innovative way of controlling the airflow.

Our Constant Airflow Controller is able to maintain a constant airflow by sensing and compensating for filter differential pressure throughout the life of the filter.  This optimises extraction system performance and extends the life of filters.

The Constant Airflow controller can be retrofitted to existing extractor units.  Once installation is complete minimal attention is required.  Additional features can be included, for instance; Remote audible alarm, differential pressure alarm, bin level alarm, high emissions alarm and continuous recording system etc
