Protea 1000 - Analyser Control Unit
The Protea 1000 Analyser Control Unit (ACU) controls and processes the raw data from up to six Protea Continuous Emission Monitoring systems and generates, displays and transmits concentration readings in customer specified units.
In addition, the ACU can also collect data from third party instruments measuring, for example, dust (opacity), oxygen, temperature, pressure and velocity.
The industrial PC displays gas concentrations on the integral display along with information on sample conditions, diagnostic data and trends. The information can be retransmitted in the form of 4-20mA current outputs (one per measured component), parallel printer interface and optional RS485 serial output.
Analyser Control for Windows™ CEMS Software
Analyser Control for Windows™ is a powerful Protea application designed to run on the Protea 1000 control unit or on a stand-alone PC. The application is capable of controlling up to 8 multi-component analysers and can receive inputs from other devices such as Flow, Oxygen and Dust sensors and can present results in the form required by the Regulatory Authorities.
Networking facilities mean that the software can be installed on multiple LAN connected computer terminals and can be accessed through WAN remote devices.
Auto Zero/Auto Cal CEMS
To comply with various Environmental Agency requirements, in particular US EPA 40 CFR Part 60 & 75, the instrument has to be challenged on a daily basis. Clearly, extractive instruments can be challenged by diverting zero and the test gas into the sample cell, enabling the instrument to be recalibrated and any errors reported. This is also possible in the enveloped folded beam. Normally, the flue gas passes through the sintered panels, filling the in-situ gas cell, where the absorpton of infra red or ultraviolet light takes place.
Periodically, either automatically or on demand, a solenoid valve can be activated by allowing instrument air to be discharged into the in-situ cell, forcing out the flue gas, enabling the instrument to check zero and adjust if necessary. In the same way, certified test gas, traceable to a National Standard, can be introduced into the sample cell, enabling the instrument to check, and if necessary adjust calibration. It is recommended that the auto-zero is carried out on a daily basis, however, experience has shown that calibration verification need only be carried out every three months or so. Under US EPA 40 CFR part 60 & 75, it is a requirement to carry out these checks on a daily basis, If the instrument is outside ±2.5% on either the zero or the span, the instrument is deemed to be out of calibration for that day..
