Protea 2000

“P2000 is an infra-red (IR), duct or stack-mounted Analyser, designed to provide In-Situ analysis of up to six gas-phase emission components.

A typical system comprises of a stack mounted Analyser, an integral Calibration Module and a Control Unit with options which include a powerful In-Situ Heater and a stand-alone Analysis Software package.



P2000 uses the reflective beam principal to directly measure process gas as it enters the in situ sample cell.

Unlike higher maintenance extractive systems, Protea’s patented, sintered metal technology removes the need for gas filtering or sample conditioning.

The P2000 analyser requires very little maintenance and achieves a class-beating availability of over 98% in demanding applications.

The Control Unit can support multiple analysers from the Protea range.

Principles of Operation

Analyser: The P2000 analyser operates on the proven, single beam, dual–wavelength IR principle. Mid IR Pulses, at two specific wavelengths per monitored component, are transmitted through the sample cell. The ‘measure’ pulse is partially absorbed by the gases being measured while the ‘reference’ pulse remains unaffected.

Up to eight wavelengths are available, sometimes sharing reference wavelengths, allowing up to six gas-phase component concentrations to be monitored simultaneously. Uniquely, the operation, zero and calibration are “fully challenged” in that all operating modes use the same optical path and system components.

Auto Verification: The integral Auto Verification Unit provides a zero-check on the system by filling the sample probe with clean, dry instrument air. Similarly, it performs a span-check by filling the sample probe with certified span gas.


In-Situ CEMs Control Unit

In addition to collecting data from Protea’s P2000 and P5000 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 e.g. Kg/hour. The analyser communicates via a serial data link to the control unit, which can be located up to 1200m from the CEMS. 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.
