Davis Derby Electronic Equipment and Monitoring Systems for Harsh Environments

Davis Derby is an industry leader in the design and manufacture of electronic control and monitoring equipment and data logging systems for use in harsh environments. We have a wide range of electronic and software engineering design skills, including many years of experience in the design of explosion-protected equipment.

The MineWATCH® product range from Davis Derby provides means of equipment monitoring, control and communications in mining and hazardous/gaseous environments, particularly where intrinsic safety is an issue. All equipment designed for underground use is ATEX M1 certified and designed to the European standards of the CENELEC EN50 series.

The need to increase efficiency without jeopardising safety remains a challenge, which can be met by the introduction of cost effective computer based remote control and monitoring systems. Davis Derby supplies a comprehensive range of equipment to solve all mining control and monitoring problems.

PC21 MINESCADA REMOTE CONTROL MINE MONITORING SYSTEM

The application of computer-based remote control and monitoring systems in mines significantly enhances both safety and productivity by providing mine managers and engineers with the information and confidence they need for the safe and profitable running of the mine.

Davis Derby specialises in environmental monitoring and control systems, including the PC21, Minewide Supervision Control and Data Acquisition (MineSCADA) and battery power supplies for bunkers, pumps, fans and conveyors.

The system is a flexible remote control and monitoring system comprising of three modules, which can be used in combination for a wide variety of applications such as conveyor, pump, fan and compressor control. In addition the PC21 system is suitable for environmental monitoring applications.

Features of the PC21 include:

  • ATEX M1 certified intrinsically safe
  • Distributed intelligence for effective plant control and monitoring
  • Cost effective solution minimises hardware and cable costs
  • Units can be up to 500m apart, enabling the intelligence to be distributed
  • Extremely flexible to allow a wide range of applications
  • Expandable to suit future changes
  • The PLC ladder logic software is user programmable
  • Modules can be reprogrammed on site

The MineWATCH PC21 has three modules, these are the PC 21-1 control module, PC 21-2D display module and the PC 21-2T transmission module.

THE MINEWATCH PC21 GENERAL PURPOSE CONTROL UNIT

The MineWATCH general purpose control unit is intended for various applications, including pump control, fan control, auto-loop control, and hydraulic coupling control or compressor control.

The unit is powered from a separate 12V intrinsically safe power supply, a power supply unit with interposing relays can be bolted directly to the general purpose unit as in the case of the conveyor control unit as previously described if required. This power supply can be used to power several PC21 modules via the cluster CAN bus.
