OPSIS - Model 400 -Emissions Monitoring, Process Control System
An OPSIS System 400 always contains emitter, receiver, optical fibre, and analyser. The system is offered in three different technical versions: System 400CS where the light along the monitoring path is sent directly through the gas channel ("Cross Stack"). System 400FL where the monitoring path is placed in a bypass line with fast gas exchange ("Fast Loop"). System 400HWE where a small flow of gas is extracted at the monitoring point and led via a heated hose to the monitoring path where the gas concentration is analysed ("Hot Wet Exctractive").
In all cases, the length of the monitoring path is typically 1-2 metres, but it is often possible to use both shorter and longer sections. The choice of design depends on the conditions at the monitoring site. Read more about the systems further down the page.
Regardless of the design, the systems can be extended with additional gases, more measuring paths, and also sensors and other accessories, both when ordering and afterwards. In many cases, a single monitoring system can monitor the concentrations of all relevant substances.
We also offer System 400 packages for monitoring the concentrations of some specific substances:
- System 400BASIC: A 400CS system calibrated to monitor the levels of SO2, NO, and NO2, suitable for basic emissions monitoring at combustion facilities.
- System 400EXT: A System 400BASIC supplemented with the capability to measure the concentrations of CO and H2O.
- System 400WASTE: A System 400EXT with the addition of HCl measurement. The system is particularly suitable for monitoring emissions from waste incinerators.
- System 400HG: Basically a System 400HWE equipped with a converter and calibrated for the monitoring of both total mercury (THg) and elemental mercury (Hg0). Also this system is well suited for emission monitoring at waste incineration plants.
OPSIS monitoring systems based on cost-effective, non-contact technology provide high availability of representative data. The systems have low energy consumption and require minimal maintenance.
