Protea Analyser Control Units

System Solutions

The Protea Analyser Control Units form the hub of an advanced Continuous Emission Monitoring System.

In addition to collecting data from Protea’s advanced range of Emission Monitoring Analysers, it is configured to receive data from complementary devices, e.g. Dust / Opacity, Oxygen and Flow. This enables the system to display gas concentrations on a normalised basis and, if required, in mass units eg Kg/hour.

Protea Analyser Control Units
  • Measurement value in digital and analogue form
  • Alarm configuration and levels
  • Alarm status
  • Normalisation (equivalent correction for carbon dioxide or oxygen)
  • Wet / dry basis reporting
  • System diagnostic alarm with access to specific detailed displays
  • Autozero / calibration status
  • Analyser connection status and analyser-specific status panel screens for each instrument
Protea S-PC Software

Protea S-PC Software – Supplied to run on a conventional PC

The Analysers communicate via a serial data link to a PC running Protea S-PC software which can be located up to 1200m from the CEMS. To facilitate ease of operation, the intuitive software is designed to utilise either a pointing device or touch screen for all operator functions. The Protea S-PC is capable of supporting up to six Protea Analysers with associated third party devices.

Panel / Trend Screen

Panel / Trend Screen

Up to eight channels of historical data from any instrument are presented in X-Y chart form. On the right hand side of the chart is the identification of each measured component, its scale, the colour of the trace and the measured value.

The date and time at which the measurement was taken is indicated in the Measurement Time box in the lower right hand corner of the screen.

This time will initially be the current time (Now) but by use of the Time Scale scroll and mouse control, a dotted cursor can be moved to any part of the screen for any time and the measured value at the point selected. The Averaging Period box allows the rolling average of the measured value to be varied. Additional trend screens can be added by the User.

Test Screen

The data from each analyser is displayed on an individual test screen. The screen displays data from each measured signal, including any offset, and the current calculated concentration. In addition, it displays the analyser temperature, sample temperature, sample pressure, and up to four input signals from external sources, such as particulate, oxygen, velocity, and a set of channels derived from these measured channels.

Protea P-PC Controller

Protea P-PC Controller

This unit has been specifically designed to be located in industrial environments where conditions are not conducive to the use of a typical office PC.

The hardware consists of an IP65 / NEMA 4X enclosure containing a high-grade, sealed touchscreen panel PC with optional 4 – 20mA I/O.

Analyser Controls are intuitive using a touch screen (optional keyboard or pointing device) to switch between windows and menus.

Reports

Reports can be generated to meet the requirements of the majority of national environmental authoritys’ reporting requirements and include:

  • Calibration status report (zero and cal report)
  • Trend reports
  • Hourly, daily, and weekly averaging reports
  • Excursion report

Special reports can be configured - Please consult Protea directly

Security

To comply with environmental agency’s protocols the system incorporates three levels of password protection.

System capability

  • Supports up to six Protea analysers each with up to four third party inputs
  • Network ready allows data from multiple Protea 1000 to be displayed
  • MODBUS – Four wire RS485 Full Duplex, Standard MODBUS Slave on a plant supervisory Protea S-PC
  • WAN capability, allowing remote access for reporting and site support

I/O (Standard)

  • Print Function – USB & parallel printer port
  • Data Dump Facility – USB memory stick
  • LAN – Ethernet two ports 10 / 100 / 1000 Mbps
  • OPC/ODBC connectivity

I/O (Optional)

  • Current Input / Outputs 0 - 20 mA / 4 - 20 mA, each galvanically isolated from ground and from each other. Normally only fitted with the same number of outputs as the number of Protea ranges, third party instruments connected to the system can also be allocated outputs
  • Relay Outputs Volt-Free 28V dc 1A (n/c or n/o selectable) for channel alarms, analyser `fault’ relay, and for other functions
  • Digital Inputs 24V / 20mA logic or Contact closure detection Link Selectable
  • PROFIBUS – slave connectivity (optional)
