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.
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.
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.
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.
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 can be generated to meet the requirements of the majority of national environmental authoritys’ reporting requirements and include:
Special reports can be configured - Please consult Protea directly
To comply with environmental agency’s protocols the system incorporates three levels of password protection.
