Protir 304L

The ProtIR 304L is a process ready FTIR Mid-IR absorption analyser designed for measurement of liquids or high concentration gas mixes. Based around the proven ABB MB3000 spectrometer, the 304L contains a quickly removable sample compartment accessory with single pass sample cell. Sample cells of pathlength 1 – 12 cm can be loaded into the sample compartment box, together with sampling sensors for pressure, temperature and flow.

The 304L runs a dedicated sampling system control package that is proven over many process and emissions systems. As well as monitoring sample condition (pressure, temperature etc.) the sampling system electronics relays digital and analogue outputs from the system. An integrated PLC can be programmed to give the required automation of sampling (purge valves, sample stream selection) for any given application.

The 304L is run via a dedicated PC, either panel mounted in the analyser cabin or a remote desktop PC. PAS-Pro software collects and analysers the spectral data, as well as providing all the alarm and sampling management for the 304L. Data is available on a dedicated OPC server for retrieval by plant.
